Nutritional
Supplementation For GoatsBy Robert L. JohnsonGood nutrition is equally important to all living things, yet
although many studies have been made on the feeding of cattle,
sheep, horses, swine, dogs, cats and birds, the minor economic
status of the goat and the folklore about its dietary habits has
caused little research to be done on its basic differences and
particular needs. The modern dairy goat has been bred to produce
a great quantity of milk in proportion to her body weight, yet
she is descended from, and carries the characteristics of, her
wild ancestors that roamed vast land areas, selecting for their
needs from a great variety of browse and forage plants, getting
no supplemental grain, and producing just enough milk to feed
their kids for a couple of months. Natural selection favored goats
that were tough, hardy, and resistant to disease. We have penned
this creature in a comparatively small area, thus exposing her
to very limited browse (if any) and to concentrated parasite burdens,
and we have bred her to produce superabundant quantities of milk.
Unless her diet is adequate in both quantity and quality, we are
asking the impossible of her; and opening the doors to poor health,
disease, lessened production and shortened life span.
Conventional wisdom and modern books on dairy goats treat them
as animals with productive life spans of 7 or 8 years. Many goats
do not even survive that long, although old magazines, books and
records show that goats in the past lived 12 to 18 years, often
productive to the last. Good nutrition will do much to offset
the ill effects of our relatively un-natural husbandry methods
and breeding efforts. It is important to remember that our modern
high-production dairy goats have nutritional needs that are not
easily met, especially on conventional diets of hay, too much
grain, salt blocks and water.
There are a few major considerations to ponder, prior to delving
into a nutritional-supplement program.
First: nutrition is not a cure-all for all ills of animals
and man. Good nutrition will help prevent many disease problems
from arising in the first place; for the immune system of an organism
weakened by deprivation obviously is not functioning effectively.
But nutritional deprivation is not the sole cause of disease.
Genetics plays a big role; some animals are born with inefficient
immune systems, different degrees of assimilation and feed-conversion
efficiency, and/or predisposition to certain ailments. Goats are
kept under a great variety of husbandry methods, some of which
may induce stresses, increase the chance of accidents, or expose
the goats to concentrated burdens of disease-producing organisms
(or poisons) that overwhelm their defenses. When one is promoting
something new, it is natural to emphasize the merits and downplay
the demerits, in the attempt to persuade the unconvinced. Then
when the person taking the new supplement becomes ill, or is not
helped, it is perhaps human nature that he would conclude that
the new product was of no merit, and further trials are often
abandoned. Thus many nutritional therapies that might have worked
do not get the chance–especially as we Americans, being impatient
folk used to instant results (such as taking an aspirin and getting
immediate pain relief) are not used to the slower response times
of some nutritional therapies. When you're anxious about a sick
animal, desire for fast results is understandable. One must always
remember that antibiotics and drugs act in different ways from
nutritional elements - the former act on the symptoms; nutrition
acts systematically to restore health and optimum systemic function.
On the other hand, to use nutritional therapy alone in the face
of active disease requires a good understanding of what ailment
one is dealing with, as well as the actions of the various nutrients.
Vitamins and minerals given in moderate to large doses as adjuncts
to other therapy are one thing and such treatment is supportive
and beneficial. To use supplements alone in massive therapeutic
doses, without additional treatment, is quite another; in certain
ailments use of such treatment involves the risk of losing the
animal. Thus one must exercise good judgment as to when to try
home treatment including nutritional therapy, and when to seek
professional help. Remember always that vitamins, minerals and
amino acids all work together and in a delicate balance;
to use massive doses of one or two is to upset this balance, and
there are but few times when this is indicated. It is always easier
to prevent disease than to cure it; prevention is the purpose
of nutrition - a well-nourished goat will have a healthy immune
system which will speed healing and fight off most bacterial and
viral invaders; after these have overwhelmed the defenses and
produced sickness, additional help may be needed.
Second--The economics of animal-keeping plays a decisive
role in terms of decisions as to the kinds of food supplements
and treatments to employ. In large herds, such as commercial goat
dairies, the time and cost invested in feed supplements and treatments
must of necessity be more limited, and the herdsperson doubtless
has already established basic parameters for his stock, including
the decision to cull animals that are "poor doers" or
always coming down with something, whatever their other merits,
and to spend within a budgeted amount for feed supplements and
treatments. On the other hand, breeders with some very valuable
breeding stock, or the family with a few much-loved pet goats,
may devote whatever time, money and attention the health and treatment
of their animals requires. Most of us fall somewhere in between
the two extremes--but whatever we wish or expect from our goats
will determine the amount we are willing to invest in them. If
you are happy with a goat that milks well for 5 or 6 years and
you have plenty of replacement stock, you may conclude that your
animals can get by on lower-cost, lower quality feeds, without
'elaborate, expensive' additives. If you are interested in developing
a line of stock that will live, milk and kid happily for 12 to
16 years, you will benefit and make progress toward your goals
by investigating, studying and applying nutritional supplementation.
Nutritional supplements are used in three ways--as dietarysupplements to build and maintain health and hopefully
prevent the onslaught of disease; as supportive treatments,
in combination with other therapies, and alone in therapeutic
doses as the sole treatment. The subject of nutrition is too complex
to attempt to completely cover in an article such as this; thousand-page
books on the subject exist that still leave unanswered questions,
and research is still ongoing. This article is intended to provide
basic information on the known nutrients and practical instructions
to the goatkeeper. We'll omit reference to therapeutic treatments
save for a couple of safe examples, and will concentrate on brief
descriptions of the vitamins and minerals, their functions in
goats, and their provision beyond amounts normally provided in
feeds, hays and browse.
The MineralsWe will discuss the minerals first, since goats have the highest
requirements for minerals of all ruminants on a body weight basis;
and as we breed our goats for greater milk–production, we
obtain animals whose mineral requirements have increased to the
point that it is difficult for them to obtain sufficient to meet
their needs from pasture, hay, and the standard dairy/grain rations
that the majority of us feed. The goat's metabolic rate is higher
and the area and capacity of the caprine rumen is larger in proportion
to body size than that of the cow, sheep or horse. In most books
on goatkeeping you will read that in the early stage of lactation,
a high-producing dairy goat cannot obtain enough protein, energy,
fibre and minerals to meet the demands of the udder, and thus
she draws on her reserves, stored in her bones, to make up the
deficit. She can only do this if her mineral "bank"
is substantial, her bones well-mineralized, and if her diet has
included the necessary minerals in the right proportion, along
with the vitamins and other dietary factors that allow for complete
absorption and utilization of the minerals she does receive.
By nature, goats are browsing- not grazing- animals.
Two reasons for this stand out: (l) the goat with its proportionately
larger digestive system is more subject to parasite attack, and
Nature teaches the goat to reach up for its food, out of
the way of the harmful stomach, intestinal and lung worms that
can do much damage. (2) The goat's high mineral requirements are
not satisfied by grass, which is very low in mineral content;
weeds, herbs and other forage plants, bushes and trees furnish
greater amounts or minerals than any of the grasses. Goats will
eat grass, but usually must be starved for vitamin A and other
nutrients that grass does contain, (as well as having no browsing
alternative) before they will. This is a dependable marker - the
success of one's mineral supplementation program can be measured
by putting goats out on grass pastures with few or no weeds or
other browse--if the goats' requirements are being met, they will
largely ignore the grass. Our own grassy hillside pastures offer
little more than a place to roam and play for our goats, and we
must mow the grass periodically or the goats let it grow up waist-
high. Only the young kids will nibble the grass as they experiment
with solid feeds; and the fresh flush of grass in the spring is
a welcome change of diet for the adult goats that are bored with
hay after a long winter. (We mow anyway, to keep the grass short
and thus enable the sun to destroy some of the parasites.) But
we daily let our goats out into a wooded area near a small creek
where honeysuckle, weeds, trees, thorn bushes, vines and blackberry
brambles grow, and they are hardly out the gate until they are
gorging on this mineral-rich, parasite-free browse. If you are
looking for animals to keep grass mowed for you, think sheep.
The goat is instinctively intelligent enough to know its requirements
and to select for these from the feedstuffs available to it. However,
most American dairy goats are kept under conditions where it is
difficult for them to meet their nutritional needs. Unless they
have access to large areas of mixed browse, their usual diet consists
of commercial dairy mixes, many of which have ingredients of unknown
qualities; hays, in many cases obtained from depleted or over-fertilized
lands and/or made primarily from single types of grasses instead
of the varied mixtures goats prefer; and often nothing more than
a salt block provided. These fall far short of providing the nutrients
in the variety and quantity that dairy goats, especially, require;
the inevitable results are off-flavored milk, loss of production,
ill health, and shortened lives.
We will not attempt here to do more than briefly list and describe
the minerals and their functions--this has been done and done
well, many times over; the information is available in a variety
of publications. Probably the best book on the subject is Feeds
and Nutrition by Ensminger and Olentine; a huge 1,417-page
volume that will tell you everything you ever wanted to know and
then some, about animal nutrition. Hundreds of other publications
discuss nutrients and their actions in animals and Man. Anyone
who intends to keep more than a couple of pet goats should search
out and read the 3rd edition of the late David MacKenzie's
classic book Goat Husbandry (Faber and Faber) which contains
the best condensed discussion of the goat and its mineral requirements
that we know of; then turn for more detailed information to Ensminger
& Olentine. This writer has stretched himself out over Feeds
and Nutrition for years and, as with MacKenzie's book, still
always finds tidbits not noted before.
The purpose of this article is to give practical instructions
to the goat-breeder in how to improve the diet and the health
of his/her goats. Let's begin with some don'ts. Be sure
that you:
(1) Do not feed salt or minerals in block form. Blocks
cannot supply the quantity of nutrients goats need; goats have
been known to break their teeth trying to work with blocks; and
some mineral blocks can become toxic if allowed to get damp or
wet. Blocks are also not balanced for the requirements of goats.
Loose salt, baking soda and mineral mixtures are a must!
(2) Do not feed any feed, protein or mineral/vitamin block
containing urea. Check the labels carefully–urea is
toxic to goats. Avoid any that contain animal by-products.
(3) Do not feed any salt, mineral or vitamin mixtures that
have flavor-enhancers added to induce consumption. We want to
make use of the goat's natural ability to select for its needs.
A sick animal, one off feed or a kid being taught to eat mixes
may need a little such tempting to get it eating; other than that,
goats' own instincts can be trusted.
(4) Do not feed minerals or other supplements out of containers
that have been used for other chemicals or that have been painted.
Salt and salt/mineral mixtures are very corrosive and will attack
all metals save stainless steel; also, the soldered joints of
some containers contain lead–and lead is an ingredient that
is not natural in the goat's diet. The goat has no instinctive
warning system against lead–in fact, goats seem attracted
to lead and lead oxides (which have a sweetish taste) as a child
is to candy. Plastic and wood, glass, or stainless steel are safe
to use.
So much for the warnings. The most important thing you can
do to meet the mineral requirements of goats is to install a mineral
feeder with multiple compartments in which you put a variety of
supplements that are always available to the goats, free-choice.
After numerous trials, Pine Cone Valley has evolved a mineral
and supplements feeder that works well. It consists of two parts:
a frame, and a 10- compartment removable tray. The feeder can
be hung on the barn wall, or, with legs added, can be free-standing.
Its slanted roof prevents kids jumping and sleeping on it. A block
placed in front allows small kids access to it. Plans are included
at the end of this article. The one described has space for ten
different products, though we usually use it for five, putting
the same things in two compartments each. Of course it may be
made longer to accommodate larger herds. Since some goats are
more timid, in large herds it is better to have two or more such
feeders and hang them in different places, than to enlarge a single
feeder. It is important not to put the feeder in an inside corner,
as some goats will feel trapped and will avoid it when more dominant
herd members are present.
The feeder is a simple carpentry project, built from wood.
So-called "one-inch" commercial boards of planed pine,
maple, sycamore or poplar, (actually 3/4" thick) are used.
The frame can be nailed or screwed together, preferably with glued
joints; one end is slotted so the tray can be withdrawn for cleaning.
Use unfinished lumber not stained, painted or treated (most
wood preservatives are poison–that's how they work; by killing
micro-organisms) especially for the tray, which the goats will
lick when compartments are empty. If you insist on painting the
frame, use latex or other lead-free paint. Paint is not
really required. Goats will push and shove to get at the supplements,
especially when you refill the tray, so be sure construction is
strong–wood screws and glued joints are best. You can fill
the compartments through the front.
The only drawback to the wood tray is that it becomes sodden
and damp and yet can't be washed out unless you use waterproof
glue in the construction. In lieu of the tray you could substitute
the inexpensive square or rectan-gular plastic food containers
available at most supermarkets, modifying the feeder's base size
to accommodate those you found. If price is no object, you can
have a fabricating shop make a tray with compartments for you
out of stainless steel.
An absolute minimum supplementation program for all
goats of any breed or type–including brush goats–is
to offer free-choice:
(1) Loose salt–ordinary table salt, iodized, is fine. We
use salt available in grocery stores. Best is mineral-rich sea
salt, but it is usually much more expensive.
(2) Bicarbonate of soda–also available from your grocer.
(3) Kelp or seaweed meal, or a good complete mineral mix including
all the trace minerals.
But the more milky the goat's pedigree, the more it will benefit
from a greater range of individual supplements from which it can
select.
Goats require, in varying quantity according to age, breed,
time of year, state of health, and individual differences:
(1) Iodine. Needed by the thyroid gland for the production
of thyroxin, an hormone which controls the rate of body metabolism,
iodine is often undersupplied in many parts of the world. Goiter–enlargement
of the thyroid gland–is Nature's way of trying to make enough
thyroxin with an insufficiency of iodine in the feed. Stillbirths
or weak kids, kids born hairless, and twins born with a live buck
and a stillborn doe are symptoms of severe iodine deficiency.
Some experienced breeders feel that iodine requirements in the
high-producing dairy goat are greatly underestimated; breeding
for high production is breeding for a larger and more active thyroid
gland. Loose iodized salt is available from any grocer; obtain
a package of organic iodine--EDDI (ethylenediamine dihydroiodide)--and
mix 1 pound of it with 25 lbs. of iodized salt; offer free-choice.
(2) Calcium (Ca) and (3) Phosphorus (P) are essential
major nutrients required in considerable quantity. Calcium is
required for bone and tooth formation, muscle contraction, blood
coagulation, cell permeability, and the production of milk. Phosphorus
is likewise required for bones and teeth; it is also involved
in energy metabolism, and a host of other bodily and cellular
functions. Calcium and Phosphorus act together, however, and it
is difficult to discuss them individually. The goat requires an
overall balance of calcium to phosphorus in the ratio of 1.25
or 1.5 to 1, and this is not easy to obtain--all foodstuffs have
both minerals but in widely varying quantities and ratios. In
very general terms, hays are calcium-rich, grains and food yeasts
are high in phosphorus--but the ratio varies widely. Some alfalfa
hays have Ca/P ratios as high as 17:1! Excesses of either must
be avoided. Too much calcium causes stiffness, joint problems
(nutritional arthritis) and an apathetic attitude. Excess P is
the major cause of urinary calculi in bucks, usually caused by
giving them the lower-quality low-calcium hays, along with feeding
them much grain. MacKenzie calls calcium a "brake" and
phosphorus an "accelerator." An excess of P is unlikely
in natural browse (it is in rather short supply in nature) but
in an artificial diet (too many concentrates) it could be oversupplied
and cause high-strung, fidgety goats that look well, eat well,
then kid and die! Since we want to be certain that our goats can
balance their Ca/P intake, we supply milking does with Monosodium
Phosphate or Dicalcium Phosphate free-choice which gives them
a chance to balance any hay/grain combination fed to them. A lack
of either can cause rickets in young stock, osteomalacia (which
literally means 'bad bones') in adults. Sufficient vitamin D is
required for calcium assimilation; adequate vitamin D can allow
ruminants to tolerate a wider Ca/P ratio. Excess magnesium decreases
calcium absorption. Excess calcium reduces absorption and utilization
of zinc. Over 70% of all the minerals in the goat body are Ca
and P; 99% of the calcium is present in the bones and teeth. Other
good sources of Ca & P are bone meal, deflourinated phosphate,
and of course, milk.
(4) Iron (Fe) is part of hemoglobin, the compound that transports
oxygen to all the cells. Iron-deficiency anemia is characterized
by red blood cells that are smaller than normal.
(5) Copper (Cu) is required for the proper metabolism
of iron, and is essential in enzyme systems, hair development
and color, bone development, reproduction and lactation. Excess
copper is toxic (levels above 250ppm) but deficiencies are indicated
by fading hair coats, light hair growth, nervousness, lameness
and swelling of the joints, and a type of anemia called 'salt
sick.' In areas where molybdenum levels are high, extra Cu is
required.
(6) Cobalt (Co) is involved in hemoglobin formation
also, as well as being a component of vitamin B-12. The three
(Fe, Cu, & Co) work together and in feed additives, supplements,
and injections, all three are found. Anemia is common in goats
that are carrying a burden of parasites. Goats have particularly
high requirements for cobalt, which is essential for the synthesis
of vitamin B-12. These three minerals build red blood cells, and
are needed in greater quantities in the "kept" or domestic
goat, who is more subject to intestinal parasites than his feral
or wild relatives who keep on the move and never browse the same
area twice. Kids have higher requirements for iron and copper
also, as milk is a poor source of both and thus one often sees
kids nibbling dirt, trying to get the iron & copper they need,
which would normally be OK in the wild, but in domestication they
are getting a load of parasites in the process! Iron is available
in the form of iron oxide, ferric ammonium citrate, ferrous sulphate,
ferrous fumerate, and in other forms; the best is ferric ammonium
citrate which is well-absorbed. Iron oxide is very poorly absorbed.
Since copper can be toxic, this is one reason for the importance
of not adding flavorings to mix-tures that contain copper, possibly
causing over consumption. Molasses, particularly blackstrap, is
rich in iron; an excess supplies too much sugar, however, for
it to be the sole iron source.
(7) Potassium (K) is another absolutely essential mineral
that becomes of greater importance in goat diets as we increase
the amount of grain fed, and/or increase the protein in the ration.
Potassium influences carbohydrate metabolism, muscle activity,
and various other functions and a deficiency may cause growth
retardation, general muscle weakness, diarrhea, distended abdomen,
emaciation and depraved appetite; eventually death, usually from
heart failure, follows severe deprivation. Roughage usually contain
ample potassium; vinegar in the drinking water is a good source
of potassium; and potassium chloride is available--your grocer
sells an (expensive) version of it called "lite salt"–but
animal-feed-grade potassium is also available. It is put out free-choice
as obtained. Apples are excellent sources and goats usually relish
them; one might well re-word the old saying to "an apple
a day keeps the veterinarian away." Often you can obtain
bags of small apples inexpensively; some grocery stores may even
give you apples (and other fruits and vegetables) that are past
their prime and being discarded. Protein pulls minerals, especially
potassium, from the tissues, hence one of the dangers of high–protein
diets.
(8) Salt--sodium chloride--(NaCl) is needed in great
quantity by all ruminants and goats are no exception; everyone
knows that--right? Maybe the amount they need is not so
well understood, though, since people still put out salt blocks--a
bit of incorrect goat folklore that dies hard. Iodized salt from
the grocery store is as good as any; mixed half and half with
ice cream salt, or pickling salt, it doesn't cake quite as badly
as the fine granules of table salt–but if you use ice cream
salt, be sure to add EDDI for iodine. Excess salt is human diets
is considered very unhealthful; but ruminants, being strict vegetarians,
are different–remember that, while vitamins and minerals
act the same in goats, other animals and people at the cellular
level, there are some great differences in the requirements for
these from species to species–for one thing, people are not
biological vegetarians, (we are omnivores) and not bred to produce
copious quantities of milk, eggs or hair! Sodium and Chlorine
are the most important items that regulate the osmotic pressure
and acid-base balance in bodily fluids. Thus they control the
transfer of all nutrients to the cells, the removal of wastes,
and the maintenance of water balance in the tissues. Salt deficiency
can cause reduced growth, poor feed utilization, weight loss in
adults, and reduced production. Salt toxicity is primarily caused
by restriction of water intake.
(9) Sulfur (S) is a precursor of some amino acids (cystine
and methionine), and is a component of biotin, thiamin and co-enzyme
A; thus it is important in carbohydrate, energy and lipid metabolism.
Increasingly, goat breeders are becoming aware of its beneficial
effects in goat health. Sulfur licks are available from feed stores;
these can be broken into small pieces with a hammer and put in
a compartment of the mineral feeder--they are about 1% sulfur
and 99% filler. Some of these are sufficiently soft so that they
can be put out in lick form and the goats will obtain the little
bit they need which is the one exception to the rule of "no
blocks." You can get pure powdered sulfur, which can be offered
free-choice (in small amounts, so it won't become unpalatable)
from the drugstore.
(10) Selenium (Se) is much in the news lately. It acts
in combination with vitamin E and in some cases each can "pitch-hit"
for the other, but no one knows exactly what all its functions
are. Selenium can be toxic; a tiny bit is essential but one must
not overdose. Some trace mineral mixes contain selenium; also,
food yeasts are rich in selenium in organic and readily assimilable
form. We rarely give Bo-se injections nor recommend them for routine
use except in particular circumstances–i.e. where white muscle
disease and/or poor buck fertility has been a herd problem, or
forages are known to be deficient. Recent studies have shown that
Bo-se is poorly absorbed, and is gone from the system in 12-14
days–the kidneys work hard to excrete the excess following
the injection, and the goat is not much better off. (However,
Bo-se is traditionally given as an IM injection; we have always
given them sub-Q for slower absorption - maybe these studies used
them IM also.) Tiny amounts regularly in the feed and provision
of trace minerals provide a continuous usable supply. High-protein
rations tend to protect against selenium toxicity. Bucks in heavy
service require extra selenium. 200-300mcg Se per goat, usually
in trace mineral mixes at 20-30 ppm, is believed at present to
supply adequate amounts. Some parts of the country contain high
levels of Se in the soil, and thus grains and hays grown on such
soils can cause toxicities–including blind staggers, sloughing
of hooves, anemia, grinding of teeth, excess salivation, paralysis,
blindness, and death.
(11) Magnesium (Mg) is essential for normal skeletal
growth, and as an enzyme activator; it keeps calcium from being
deposited in joints and soft tissues. "Grass staggers"
or grass tetany is caused by a lack of magnesium; symptoms include
nervousness and irritability, loss of appetite; eventually convulsions
and death ensue. A complete goat trace mineral mix must contain
magnesium. High-protein diets increase magnesium excretion and
can cause deficiencies. Magnesium is the 'red cell' of plants
and usually better supplied in ruminant diets than human foods;
our brief discussion of it is not, however, intended to minimize
its importance–it is a major essential mineral. A calcium/magnesium
ratio of 2:1 to 1:1 in foods is considered normal.
(12)-(13)-and so on. More? Yes; periodically, studies are released
showing the activity of and necessity for, other minerals, usually
in very tiny amounts but nonetheless essential. These includeManganese, essential for bone formation, growth and reproduction;Zinc, needed for bone development, protein synthesis; and
mobilizing vitamin A out of storage in the liver; Silicon,
involved in the mineralization process; Molybdenum, which
stimulates the action of rumen organisms; Chromium, which
regulates the activity of the pancreas and glucose metabolism,
Barium, Boron, Fluorine, Lithium,
Tin, Vanadium, and many others, including many whose
exact functions in human and animal nutrition are not yet fully
understood. Most of these are available in sufficient quantities
in natural browse and hay; and are not added to trace mineral
mixes; in some cases excesses are the problem rather that shortages–selenium
in some areas; molybdenum in others; fluorine in some water sources.Kelp Meal is relished by goats, and is a rich source
of all the known trace minerals including the many whose needs
and functions are not fully understood. It is high in calcium,
and if offered, food yeasts should be fed to enhance absorption;
especially if alfalfa hay is being fed also.
The important point is that all vitamins and minerals work
together. Just as a complete house cannot be built with nails,
shingles, and concrete blocks, so a whole goat cannot be made
with only some of the nutrients supplied.
(14) Bicarbonate of Soda–not exactly
a "trace mineral" but a necessary free-choice substance
to keep in front of goats at all times. The goat's rumen pH--the
acidity–alkalinity balance–must be kept within narrow
limits. Grain makes the rumen highly acid as do some illnesses,
and the result is the dying-off of the rumen microflora, that
digest and utilize the food eaten by the goat. This starts a vicious
cycle–poor absorption of badly-needed nutrients, then even
more depressed appetite, eventually leading to acidosis. Many
finicky eaters and metabolic problems can be cured simply by offering
a buffer such as bicarb. Your grocer has bicarbonate of soda (Arm
and Hammer baking soda, for example) available.
In the mineral feeder or "cafeteria" we put the following:
(1) Loose salt, with EDDI added if rock salt is included,
(2) Bicarbonate of soda,
(3) A complete mineral mix, with extra potassium chloride if feeding
high-protein grain to heavy milkers,
(4) Dicalcium phosphate or monosodium phosphate, straight or mixed
half and half with loose salt,
(5) Kelp meal. Also, we vary the contents of this from time to
time. After putting out new-cut alfalfa hay, we offer a live-cell
yeast (Diamond V brand) to supply additional phosphorus and nourish
the rumen microflora; which helps prevent bloat.
When first putting out the free-choice supplements, begin with
only a small amount of each, to check on consumption and to prevent
spoilage until the goats accept them. The tray compartments will
hold a lot of minerals. Some of these, especially the loose salt,
may "skin over" on top if you fill the compartment full,
especially in humid weather, and the goats will be reduced to
licking as if it was a block; small quantities added frequently
will be consumed before this can happen. You can break this "skin"
with a knife or screwdriver. Initially, some goats may refuse
some of the minerals that are new to them; give them time–usually
no more than a week is required until they become accustomed to
the new "goodies." It is fascinating to watch them at
the feeder. Each one has a different set of preferences and requirements
and they will move from item to item, back & forth. After
the first week, if you have one or more that still consume extraordinary
amounts of certain supplements, don't be alarmed; this simply
indicates how badly they may have been needing them. Most of the
suggested supplements have salt in them, which acts as a limiter
to consumption.
Part Two: The VitaminsIn this section we discuss the vitamins, which are dispensed
to goats in a different manner from the minerals. In this article,
as in any of the many books on nutrition, animal and human, vitamins
are discussed individually. The specific functions each vitamin
is known to have are pointed out, and often in books charts of
food-stuffs are included with the vitamin and mineral content
of each given. This may be helpful in determining what nutrient
or nutrients might be useful in solving health problems, and correcting
deficiencies. However it is important to keep in mind at all times
that the actions of all vitamins and minerals in the body are
synergistic–a four-dollar word meaning that they work best
together. Suppose you have a job assembling lawn-mowers. One company
supplies you with engines, another with wheels, a third with the
metal frames, and a fourth supplies the cutting blades. One week
you get 10 engines, 10 frames, 28 sets of wheels and 8 blades-obviously
that week you can only build 8 lawnmowers, even though you have
extra engines and frames and a big surplus of wheels. If you got
100 or 1,000 extra wheels, you still couldn't build any more lawn-mowers
until you got the rest of the parts. So it is with the vitamins
and minerals–great excesses of some won't compensate for
a lack of others; all are essential to a healthy animal or person,
whose every body cell is supplied constantly with all the nutrients
it needs. The goatkeeper is not likely to see clear-cut single-nutrient
deficiency symptoms in his or her herd. Some deficiency symptoms
are even difficult to create experimentally in the laboratory.
The literature is full of case histories that seem contradictory.
Say, for example, a goat was diagnosed as having a vitamin-A deficiency,
and subsequently given a high–potency injection of a commercial
A/D preparation; yet no change or improvement was noted. Then
later, given a much lower-potency oral dose, she makes a dramatic
recovery. What does this mean? That particular goat may not have
been able to utilize the injected form of the vitamin–or
possibly the batch was outdated or spoiled–or her assimilation
efficiency from the gut was very high–or the injected dose
was in fact working over a period of time, but the oral dose got
the credit! Not easy, this type of research!
The vitamins are more "fragile" than the minerals–more
subject to denaturing by the effects of light, heat and exposure
to air, long storage, etc. The vitamin content of plants varies
day to day, season to season; at some growth stages, plants are
very high in some vitamins while at other times their content
of the same vitamins may be negligible. The making of hay is a
delicate (and chancy) operation if nutrients are to be preserved;
bale too soon and it will mold; too late and the sun will destroy
vitamin A, some B vitamins, and C. Seasonal changes, soil type
and use of fertilizers have their effects on the nutrient contents
of plants. Thus it is no more "un-natural" to heavily
supplement your goats with vitamins and minerals than it is to
breed high-producing dairy goats in the first place!
Vitamins are divided into water-soluble and fat-soluble types;
we'll deal with the fat-soluble ones first.
(1) Vitamin A (retinol) is a colorless fat-soluble
substance (actually a long-chain alcohol) with many functions
in the body. Perhaps its main one is the maintenance of the health
of the epithelial tissues-the respiratory, urogenital and digestive
tracts, and skin. It is needed for bone growth and night vision.
Vitamin A is an animal product–plants manufacture precursors
known as carotenes or provitamin A, which the body transforms
into vitamin A. This transformation is not 100% efficient; less
than 35% of the carotene is changed to vitamin A in healthy animals
and Man. (You hear a lot about carotenes in human nutrition in
the media now, as studies have shown that there is a link between
carotene consumption and cancer prevention.) There are several
forms of carotene, but the form with the highest vitamin-A activity
is beta-carotene. Synthetic forms of vitamin A are acetate
and palmitate which are usually supplied in injectable vitamin
A preparations. Most of us are familiar with cod liver oil as
the major A supplement form for humans, but being an animal product,
it must not be given to goats!
Vitamin A is extremely heat-sensitive, and is destroyed by
oxidation. Good sources of carotene are green, leafy hays not
over a year old, lush green pastures & browse, green and yellow
peas and corn, whole milk, and best of all, carrots, from which
the name comes. Deficiencies can cause night blindness, reproductive
failure, stunted growth, loss of weight and appetite, sterility,
and loss of defenses against diseases that gain admission by the
epithelial tissues. Vitamin A can be stored in the body, but young
kids have little storage capacity; when disease strikes, stored
A is rapidly depleted.
Vitamin A is one of the very few that can cause problems if
given in excess, yet the amount required by goats is not clear,
and is subject to change on a day-by-day basis. Carotene excess
is no problem; goats convert the needed amount to A and excrete
the rest, so since several thousand units of A are believed to
be needed daily, and growing kids, high-producing does and sick
goats require greater amounts, we prefer to supplement with carotene
rather than synthetic/injectable forms. Again, you can often obtain
discarded carrots and carrot tops from grocers.
Vitamin A's infection-fighting ability makes it very valuable
to use for any goat disease. It will not interfere with the action
of any medication, and is valuable as supportive therapy; while
you're waiting for the vet to arrive, you can give an injection
of A (250,000 units for a young kid up to 1,000,000 units for
a large doe or buck). Since A is stored, one repeats these injections
no more frequently than once every 7-8 days, or as the vet instructs.
(2) Vitamin D ergocalciferol (D2) or choleocalciferol
(D3) has been called the "sunshine" vitamin for years,
and animals that spend much of their time outdoors will get most
of the D they need from the action of sunlight on their skin.
D is essential in the assimilation and utilization of calcium
and phosphorus; it is necessary in bone development, normal blood–clotting
and heart action. Less D is required when Ca and P are in balance
in the diet. D deficiencies cause rickets in young animals and
osteomalacia (literally "bad bones") in mature ones.
Synthetic D is routinely (and unwisely) added, by law, to milk
for human consumption (400 i.u. per quart). Excess doses of D
can produce problems–deposition of calcium in joints and
soft tissues, the cardiovascular and urinary systems. Sun-cured
hays and irradiated yeasts are good sources of D; plants contain
the precursor of D2. Injectable forms of A with D are available;
the D is beneficial to goats in lactation that have high requirements
for Ca and P and thus for D to aid in Ca/P utilization. Goats
kept indoors in confinement require a little supplemental D. But
injectable A and D should never be given more than once every
month for prophylaxis - the problem being that to date it has
been impossible to find an injectable source of A alone without
the D included, and who wants a goat with solidified lungs from
too much D? (This would take a great excess of D given over a
long period of time.)
(3) Vitamin E (tocopherol) has come under the
spotlight in recent years due to its effects on reproduction and
prevention of heart disease. It acts as an anti-oxidant, thus
small amounts are often added to feed mixes to prevent spoilage;
as a preventer of the formation of scar tissue, and in animals,
aids in vitamin C synthesis. It is involved in some amino-acid
metabolism, and acts in combination with selenium to protect cells
from the detrimental effects of peroxidation. (Confused? Well-maybe
this will help; E and selenium each take a different approach
to the peroxidation problem; E will correct some aspects that
selenium won't, and vice versa, so both are needed, and as with
all nutrients, they work best together.) Most of us have heard
of white muscle disease and many of us give Bo-Se injections to
prevent this, and assure proper muscle development in kids; A.I.
technicians saturate bucks with selenium and vitamin E prior to
collecting semen; selenium is necessary for the formation of semen.
There are 5 different tocopherols, but the alpha form is the
one most active in the body, and that dose potency is measured
from. How much is required is a subject of debate. People interested
in nutrition take hundreds, even thousands of units daily, to
promote scar-free healing of injuries, protect the heart muscle,
and in the hope of improving libido, (which E does not help, but
zinc does; though E does affect reproduction.) In goats, some
mastitis organisms change normal milk-secreting tissue to scar
tissue; there have been a few reported experiences of the reversal
or mitigation of this by massive doses of vitamin E. Since E reduces
the need of the cells for oxygen, in these days of air pollution,
extra E would benefit man and animals alike. Excess doses are
non-toxic.
E is supplied in the plant germ and germ oils, wheat especially;
in sun-cured hays and green plants. We give extra E to any goat
that shows a positive reaction to the CMT test, and we have given
1,000 i.u. twice daily to does with mastitis or off-flavored milk.
Since goats don't like powdery feeds, we administer large dosages
by piercing the capsules of E available at health-food stores
and squeezing the contents into the goat's mouth or on their grain.
E has a tendency to raise blood pressure in animals not used to
it, so initial intake should be small, (not over 1,000 i.u.) and
doses increased over a period of time. Vitamin E has been used
quite successfully to clear up off- flavored milk; the treatment
is to give 1,000 iu once a day for the first couple of days, then
increase the dose to 2,000; usually by the end of the second or
third day the milk will clear up. Give at this level for a week,
then withdraw; if the problem returns, administer E again. We
have heard of E being infused into the udder of a goat with mastitis;
we've not tried this, but obviously it would have to be done after
the mastitis had been treated and the causative organism killed;
E might prove to be a wonderful food for the mastitis pathogen!
Such would be risky even then but if someone has an old doe with
an udder full of scar tissue from past bouts of mastitis and wants
to try experimenting, infuse 2,000 or more i.u. daily after milking
and let us know what happens! If the scar tissue has not been
present for years, it should eventually dissolve under the E treatment.
A better way to accom-plish this would be to mix vitamin E with
80% DMSO (dimethyl sulfoxide) and apply topically to the udder
every four hours for a few days. In all such cases, E should be
also supplied by injection or orally. E oils are excellent to
apply to burns, to abraded, chapped or roughened skin, and to
cuts or suture sites after they have begun to heal, to prevent
scar tissue formation.
(4) Vitamin K (menadione, or K3) is a heat-stable,
light-sensitive vitamin that is essential for its involvement
in the clotting of blood. Lack causes hemorrhages, prolonged clotting
time, even death in severe cases. However, it is synthesized in
the digestive tract of animals and Man, and is rarely added to
animal feeds, in small quantities only. It need not concern goatkeepers;
it is present in pastures and hays, and it should not be
taken except on the advice of a veterinarian, who might use it
in treating an animal that had ingested the rat poison Wafarin
(which kills by causing internal hemorrhages) or for animals that
had prolonged oral antibiotic therapy, which alters the rumen
microflora and causes losses of vitamin K; or prior to (or after)
surgery.
The fat-soluble vitamins are capable of being stored by the
goat's body and these stores drawn upon for use as needed. But
the water-soluble vitamins are not stored, and are required in
the diet every day, if health, even life itself, is to be maintained.
To some degree, these vitamins are synthesized in the digestive
system of the goat; provided the precursors are available in the
diet for them to be synthesized from; however this mechanism is
easily upset by such things as stress, moldy feed, the invasion
of disease-causing bacteria, etc. and recovery from illness is
considerably sped up by inclusion of extra vitamins and minerals
in the diet of the ailing goat. More importantly, as an ounce
of prevention is worth a pound of cure, so it is better to be
certain that sufficient vitamins and minerals are present in the
diet of the healthy goat, as a fortress against disease. Nutritional
supplementation is good insurance; the well-fed doe is better
prepared to withstand extra stresses, heavy lactation, pregnancy
and kidding; the buck, the demands of heavy service. It is always
better to prevent than to treat!
The water-soluble vitamins are primarily the B-complex family
and C. These vitamins work closely together and rarely is it necessary
or desirable to increase feeding or injecting one member of the
B family over the others.
(1) Vitamin B-1 or Thiamin is the compound
that was discovered to prevent beriberi in people and polyneuritis
in birds, in 1927. Its effect on the central nervous system has
resulted in it being called the "morale vitamin". It
is necessary for the breakdown of carbohydrates, for growth, muscle
tone, digestion and assimilation of food and stabilization of
appetite. Thiamin deficiencies can cause fatigue, loss of appetite,
labored breathing, gastric distress including cramps, indigestion
and constipation, and depressed growth. B-1 is water-soluble,
thus absorption is rapid and efficient in the large and small
intestines. It is very sensitive to heat and air. Good sources
of thiamin are wheat germ and middlings, bran, corn germ, linseed
meal, soybean meal and especially the food yeasts.
Thiamin injections are on occasion given to treat specific
conditions, such as to aid in repair or prevention of polioencephelomalacia,
nerve damage caused by fulminating diseases, or the consumption
of moldy hay or grain. However, large doses (over 50 mg) of thiamin
hydrochloride--the usual injectable form--should be administered
slowly, as anaphylactic shock reactions, though rare, have been
reported; check the potencies of the thiamin content of any B-complex
injectable you plan to give. Orally, thiamin is non-toxic; any
excess amount would simply be excreted; but oral pure thiamine
is degraded by rumen bacteria and may not be absorbed - this is
believed to be true of all the vitamins of the B-complex.
(2) Vitamin B-2 or Riboflavin is involved
in the breakdown of carbohydrates, fats and proteins, and the
production of energy. It is necessary for cell respiration and
maintenance of good vision, skin and hair. While Riboflavin is
heat-stable, it is readily destroyed by light and alkalinity.
Deficiencies are non-specific; lack of it can cause re-tarded
growth rates, poor feed conversion, lesions of the mouth and tongue,
dermatitis, and poor hair coat. Good sources are dairy products–milk,
whey, buttermilk–and alfalfa hay, peanut meal, leafy forages,
and food yeasts.
(3) Vitamin B-3 or Niacin is the anti-pellagra
vitamin, present in the healthy body in larger quantities than
any other vitamin. Niacin is the most stable of the B-vitamins,
and consequently amounts remain in foodstuffs, largely unaffected
by light, heat, air, etc. It is vital to the nervous system, the
synthesis of sex hormones, the formation and maintenance of skin,
tongue and digestive tissues. Poor circulation is often a niacin
deficiency; likewise diar-rhea, mouth lesions and enlarged hocks.
There are three synthetic forms: niacinamide, nicotinic acid and
nico-tinamide, which function as well as niacin in most of the
body's uses of niacin, though not all. Niacin is found in sunflower
seeds, wheat bran, rice bran and polishings, and yeasts (the best
sources) though forages and other grains have a moderate amount.
(Meat, especially organ meats, are excellent sources for humans.)
(4) Vitamin B-6 or Pyridoxine plays a
number of important roles in the body--the breakdown and utilization
of feeds, nervous-system maintenance, the production of red blood
cells and antibodies, the release of glycogen from the liver for
energy, the balance of sodium and potassium, and the synthesis
of RNA and DNA. Pyridoxine is sensitive to light, though stable
to heat. The need for B-6 increases during pregnancy, lactation,
and old age. B-6 is well-supplied by soybean meal, sunflower seeds,
wheat and yeast; alfalfa is a moderate source, as are other grains.
Molasses, included in most dairy feeds, is a good source.
(5) Vitamin B-12 or Cyanocobalamin is
one B-vitamin that goatkeepers eventually hear about, as the "appetite-stimulating"
vitamin; injections of B-12 are given to get goats back on feed.
It is the only vitamin that is linked to minerals; cobalt must
be present in the goat diet in order for B-12 to be synthesized.
B-12 is a fragile vitamin, sensitive to light, heat, acids and
alkalis; and virtually the only good sources in feeds for goats
are the yeasts and alfalfa; most plants don't contain any appreciable
amounts–meats are the best human sources, but for goats,
synthesis in the intestines is the normal source. Only very small
amounts are required and the dosages for animals and humans are
measured in micrograms.
(6) Biotin, once called vitamin H, like thiamin contains
the element sulfur. Light and heat don't seriously affect Biotin,
but strong acids and alkalis can destroy it. No deficiency symptoms
are unique to Biotin, although as with other B-complex vitamins,
deficiencies will cause loss of hair, dermatitis, depressed growth.
Biotin is synthesized in the goat's intestines; however, prolonged
use of sulfa drugs can kill the organisms responsible for the
synthesis. Good sources of Biotin are alfalfa, barley, linseed
meal, milo, peanuts, rice, soybeans and wheat, and molasses and
the food yeasts are excellent sources.
(7) Choline is utilized in much larger quantities than
the rest of the B vitamins; and the body can synthesize considerable
amounts–there has been some argument as to whether Choline
should really be classed as a vitamin since it serves more structurally
than catalytically as vitamins do. Choline is involved with fat
metabolism and transport and nerve transmission, and thus in turn,
muscle contraction and heartbeat. Lack of sufficient Choline will
cause growth retardation, fatty liver, reproductive failure, kidney
hemorrhage, and even death if deficiencies are severe. In practice
this rarely occurs since some is synthesized in the body and most
common feeds contain Choline, but assuring ample supply in feeds
is good insurance. Excellent sources are alfalfa, barley, cottonseed
meal, hominy, linseed meal, oats, peanut meal, rice bran, sesame
meal, soybean meal, sunflower seeds, and yeasts; good sources
include beet and citrus pulps, corn, millet, sorghum and wheat.
(8) Folic Acid once was known as B10 and B11.
It is required for the synthesis of purines, thus a lack will
result in abnormal maturing of blood cells, creating a type of
anemia. Generally it is abundant in nature; excellent sources
are wheat, yeast, the oil meals; good sources include corn and
oats, rice, rye, buckwheat and beets. Aged goats require greater
amounts.
(9) Inositol is another compound which is controversial
as to its classification as a vitamin. Many of its functions are
not completely understood yet; actual deficiencies resemble those
of B-6, though these are usually seen only in the laboratory,
as inositol is also present is adequate amounts in most animal
feeds. Goats grazing coffee beans in tropical countries have developed
inositol deficiencies since caffeine is antagonistic to inositol.
(10) Pantothenic Acid once called vitamin B-3,
is known to vitamin-takers as the "anti-stress" vitamin.
The name means "acid found everywhere" and it is well-supplied
in most feeds. It is rarely found in free form in nature as it
is highly susceptible to destruction by heat, acids and alkalis.
It is known to be involved with Coenzyme A in feed metabolism;
laboratory animals fed large amounts of pantothenic acid survived
such tests as swimming in cold water much longer than those that
didn't receive the extra. Most feeds contain good, if not excellent,
amounts (yeast is a rich source) and commercial salts are available.
Pantothenic acid will increase life span (in all mam-mals, including
humans) in part by its aid at preventing the effects of stress,
including adrenal exhaustion.
(11) PABA or Para-Aminobenzoic acid affects growth and
the synthesis of other vitamins and nutrients. It is produced
by synthesis in the healthy animals' intestines and the AMA has
problems with it, since it is very similar in structure to some
of the sulfa drugs; it can counteract the depression of synthesis
that these drugs can cause but it can interfere with their action
also, and various attempts have been made (fortunately not successfully)
to have it available on prescription only. The rule of thumb for
people as well as animals is that supplementary PABA should not
be given until after the prescribed treatment with sulfa drugs
- which are now not often used - has been completed. There is
evidence that it may increase the effectiveness of insulin and
penicillin.
Other vitamins that have been attributed to the B-complex are
periodically identified, and work still continues in this area.
We hear about the Russians' work with B-15; our scientists disagree
about the identification and effectiveness of this vitamin. In
human nutrition doctors still prescribe liver for certain conditions
for there are many factors in liver that may eventually be isolated
and identified as B vitamins with a proven effectiveness–taking
all the known B vitamins often doesn't produce the results that
taking them with liver does. Likewise, animals still receive injections
of liver extract for various disorders including anemia.
We inject the commercial "B Complex" for anemia from
severe parasitism, animals off feed, etc. In our experi-ence a
mixture of injectable B-complex and liver/iron/B-12 has worked
better than B-complex or B-12 alone, however B-12 has been put
on prescription and is no longer easy to get. The action of the
B vitamins is synergistic; injecting individual B-vitamins is
best left to the advice of a veterinarian as specific B deficiencies
are very hard to identify even in the lab. If a given potency
of B-12 will stimulate appetite, that same potency mixed with
the other B vitamins known and unknown (via. liver) will certainly
do better and may help the goat considerably. The trembling and
paralysis caused by thiamine antagonists in moldy feed call for
thiamine injections; we repeat–inject slowly in potencies
over 50 mg. A high-potency B-complex like Methaplex (PRN Pharmacal
Inc.) contains 150 mg. of thiamin hydrochloride as well
as 100 mcg of B-12 and other B-vitamins per ml. 1/2 to 1 ml. of
should be effective in one injection site and less traumatic to
the goat than injecting several cc of a low-potency vitamin in
more than one injection site; on the other hand we prefer larger
doses of the B-complex preparations based on 10 mg/cc of thiamine,
injected in one site sub-Q; assimilation is slower but better.
Vitamin C or ascorbic acid–the politically
controversial vitamin if there ever was one! Many volumes have
been written about vitamin C. The medical profession is sharply
divided about its effectiveness; the late Dr. Fred Klenner on
one hand has rescued humans on the verge of death with massive
doses injected IV and some veterinarians have had the same results
with animals–and on the other hand, clinical tests have been
run on groups of volunteers to see if it prevented the common
cold, with not very spectacular results–though the latter
depends on how you interpret the data, and how much C was given.
Millions of people take it, for it is widely known that Man, monkeys,
certain bats and fish and the guinea pig do not synthesize it
in their own systems, but all other creatures, including goats,
do. It is essential to life–it is involved in the formation
of collagen, the "cement" that binds cells together,
and a structural part of bones, teeth, connective tissue. It is
an important mechanism of wound repair. It combines with toxic
substances and detoxifies them; i.e. poisons, and toxins produced
by disease. It is known that the requirements increase in times
of stress, and two–time Nobel Prize winner Linus Pauling
created a furor in medical circles when he published his bookVitamin C and the Common Cold which suggested a human intake
of up to 10,000 mg.per day, this based in part on studies that
showed that animals that synthesize their own C pro-duce great
quantities of it, especially when stressed such as during the
onset of disease. No conclusive evidence has been reported that
refutes his claims.
We have personally been involved with the successful rescue
of very sick and dying goats and kids with massive doses of C,
both by injection and orally. C is very effective in combating
the mysterious "udder edema" or hard udder that plagues
many goatkeepers. The cause/s are not definitely known. Various
theories have been put forth and later exploded- hard udder has
been blamed on feeding alfalfa hay before kidding (proven not
to be the cause), on CAE virus (maybe, but some CAE-negative goats
have developed udder edema,) on Mycoplasma, (also maybe, but other
clinical signs have not appeared) on insufficient potassium and
vitamin A in the diet of the pregnant doe, and a variety of other
things. Where Lasix has failed, the administering of 10 grams
of C (10,000 mg) dissolved in an ounce or two of water and given
as a drench, once daily for ten days, has proved to be effective
more often than not. 10 grams of C is a large oral dose, and some
pasty feces during treatment have been recorded but these do not
unduly bother the doe and subside after the first day or two of
the therapy. We never experienced them in our herd. Most edema
cases begin to respond after a couple days of the C therapy. Excess
salt has been blamed as one cause of edema. Since sodium causes
water retention in the tissues, this makes sense at first look.
Vitamin C is available commercially in several forms, ascorbic
acid, sodium ascorbate, calcium, potassium and magnesium ascorbates,
which are taken by people that are adversely affected by the acid
form. In goats, the ascorbic acid alone is more effective than
the other forms, and sodium ascorbate has failed in our own trials–possibly
excess sodium is a factor in udder edema. We continue to give
and to recommend the ascorbic acid form of C as a therapy for
udder edema. Injecting vitamin C for edema is not recommended;
trials have shown that 3 grams injected IM or sub-q caused great
distress, sent the goats off feed and did not effect the edema.
Since C is destroyed by light, heat and alkaline compounds, one
should dissolve the C powders in warm water; preferably not over
110° F. The therapy works best if they get the full dose at
one time; not in divided doses.
The injectable forms of C are available in potencies of 250
mg/cc. They are painful injections; they burn at the injection
site. To get a high level of C into a goat suffering from poison
one might inject 4cc (1 gram) plus giving a drench, but the veterinarian
would doubtless prefer to give a larger dose IV, something most
goatkeepers cannot do. If one is trying to expel poisons, the
scouring effect of C is cleansing and unlike bacterial scours,
should not continue indefinitely. Always make sure that plenty
of fresh, clean water is available to goats on C therapy. Such
big doses put a load on the kidneys. Any amount of C appears to
be safe given IV - 150-gram doses have been given at one time
by clinicians for acute toxicity.
C deficiency is not to be taken lightly, just because ruminants
do synthesize their own; scurvy is the deficiency disease and
bones become weak, teeth loosen and fall out, anemia may occur,
capillaries become fragile and break; death will eventually ensue.
Yet since animals do synthesize their own C, books on animal nutrition
fail to consider it an essential ingredient in feeds, and few
commercial feed mixes contain any C, except those made for guinea
pigs. The goat that is sick may be unable to synthesize the C
it needs. We routinely add some C to their drinking water year
around, at 1 to 2 grams per 2-1/2 gallons of water. In these days
of possibly contaminated feeds and hay that may contain pesticide
residues and/or other chemicals, extra C will help detoxify these
toxins. C is also involved with the metabolism of some of the
amino acids and iron. C is not stored in the body, and any added
to drinking water is inactivated after 24 hours; after which it
should be discarded and replaced with fresh water. (Water is an
essential nutrient too–and the quantity and quality shouldn't
be taken for granted.)
Some Feeding SuggestionsAs a rule of thumb, minerals are fed free-choice, andvitamins in or on the goats' concentrate rations. Excesses
of minerals can throw a tremendous strain on the kidneys, and
some are toxic in excess (selenium, copper and others) and giving
minerals in a free-choice feeder as described in the first part
of this series is making use of the goats' inbuilt ability to
consume the minerals they need. Small amounts of the major and
trace minerals are included in many feed formulations to assure
that goats will get some; they will select for their additional
needs if given the chance.
The law of free-market economics dictates that the larger the
market, the more manufacturers will step in to meet demands. Look
through any animal-supply catalogue or at the stock of any feed
store; 99% of the listed products are for cattle, sheep, swine,
horses, dogs and cats. The variety of special vitamin and mineral
supplements made for pets and horses is bewildering and borders
on the absurd–but the demand is there! Few companies have
come to the aid of the goat; hence goatkeepers must search through
products made for animals and humans, carefully reading labels,
to find suitable feeds and supplements. Though the labels may
not say "goats" specifically, there are many products
in feed stores that goatkeepers can use. At Pine Cone Valley we
have tested many of these over the years, and will give some suggestions
here for supplemental feeds for improving goat health and production.
(1) Beet Pulp, dried, is sometimes found in feed
stores. It is high in iron and calcium as well as other minerals,
and is useful as an appetite stimulant for picky goats and does
off feed. Do not feed to bucks during breeding season,
as it may cause temporary sterility. It is a very useful, very
inexpensive feed additive that will usually cause does to clean
up their grain ration. It will definitely help reduce scours.
It will 'bulk' feeds and help satisfy the appetites of those goats
that never seem to get enough, yet get fat. A mixture of beet
pulp with a little live cell yeast is a sovereign recovery diet
for goats that are scouring.
(2) Kelp Meal (Innovators) is made of dried seaweed,
and goats love it! We feed it free-choice in our cafeteria-style
mineral feeder, and it is the first to disappear. Kelp meal supplies
the greatest variety of trace minerals of any product, including
many that are known to have a function in animal nutrition, but
the specific function is not clearly understood. Here is a complete
analysis of the product--the kelp plant most used is Ascophyllumnodosum, also known as Norwegian kelp, or common wrack.
Kelp meal is high in calcium; if you feed it, along with beet
pulp and alfalfa hay, which are also high in calcium, you must
have good sources of phosphorus available for the goats–yeasts,
monosodium and dicalcium phosphates. All figures are given in

Researchers continue to study the functions of micro and macro-nutrients
in nutrition and there is a need, tiny though it be, for minerals
such as chromium, silicon, tin, lithium, even aluminum. As work
continues, these needs will eventually be uncovered. Meanwhile,
your goats know a good thing when they sniff it–give them
kelp meal!
(3) Sea Salt undoubtedly the highest-quality mineral-rich
natural sea salt available today is harvested in France and sold
in this country as Celtic sea salt only by an organization known
as the Grain and Salt Society. Few people understand that the
salt sold for human consumption and added to nearly all foods
is not a natural product at all, but rather, an industrial man-made
mineral, sodium chloride, 95% of which is manufactured for industrial
use rather than in food. It occurs nowhere in nature in this 'pure'
form; in all natural salts including ocean water, sodium and chloride
are but two of nearly a hundred trace minerals, which is what
man and animals have evolved to consume. The elimination of all
the trace minerals - called 'impurities' by the salt companies,
and done by distillation - is now thought to be responsible for
the disease problems now linked to high salt consumption in man.

Sodium and chloride are
the main elements in sea salt, at 94%; but that remaining 6% is
vitally important in nutrition. We know less about the role of
each of the trace minerals than we do about the known vitamins.
Many of the trace minerals are needed in only very minuscule amounts
but necessary in those amounts.
Because the Grain and Salt Society exists to provide nutritional
and health information, and sea salt is an important element of
their product line, by law they cannot sell their imported Celtic
sea salt with the nutritional claims, except privately to members
of their society. Membership is quite inexpensive; the Celtic
sea salt is expensive. It is available in four degrees of fineness
and purity, including one for animals, their 'natural bath and
animal' salt, at $4.00/pound, $18 for 5 pounds or $71 for 22 pounds,
as of their last 1996 price list. Ideally, one would feed this
salt free choice, and rarely have to worry about other mineral
supplements except soda and a bit of sea kelp.
(3) Colloid Minerals you may be asking if there are
not other ways to give your goats the range of minerals they need;
yes, there are, but they are not necessarily less expensive than
sea salt. Health food stores carry several concentrated colloidal
mineral products which can be added to the drinking water. Best
known and least expensive of these is a product called Body Booster
which is the product of plant based humic shale with all the known
trace minerals in a proper balance; it is much lower in sodium
and chloride since it is from the breakdown of ancient plants
rather than sea water. A couple of tablespoons of this colloidal
mineral suspension in the drinking water is another superb way
to get minerals into your goats; combined with free-choice kelp
and Celtic sea salt, your goats should experience few if any metabolic
problems, and live long and productive lives.
(4) Vitamin C is available from health food stores
in all forms, sodium ascorbate, the mineral ascorbates, and ascorbic
acid. We suggest that it be kept on hand for the treatment of
udder edema or hard udder, and poisoning. Goats will lick all
forms out of a free-choice feeder, but this is probably not a
good way to supply it as it is likely to be denatured left exposed
to light and air. By the way–how much C do you get
a day? Everyone's need and tolerance level differs; the writer
routinely takes 12 grams--that's 12,000 milligrams–every
day; often more; and has for nearly 30 years. If your gums bleed
when you brush your teeth, you need more C!
(5) Vitamin E is provided in most feeds but in
only token amounts. Feed extra E to does and bucks, starting a
few weeks before breeding, to does that have or have had mastitis,
and to goats with any problems that involve scar tissue such as
pneumonia, lungworm, burns & scrapes, etc. E is non-toxic;
up to 5,000iu. have been given to old animals, following surgery,
and suffering from pneumonia and lungworm. E is thought to protect
the heart and to increase life span; the only reason it is not
provided in feeds in greater quantity is that it is the most expensive
of the supplements. Best sources are your health food stores.
There are four types; three synthetic and one natural; the latter,
d-alpha-tocopherol, is preferred. Dl-alpha-tocopherol, tocopheryl,
and tocopherol acetate are the synthetic forms. Unesterified D-alpha-tocopherol
with other mixed tocopherols, potency based on the alpha com-ponent,
are the best. Buy these as capsules of liquid, pierce the capsule
with a needle and squirt the contents into the goat's mouth, or
put it on their feed; for kids you can squirt some on your finger
and let them suck on it.
(6) Yeasts. The food yeasts are so rich in vitamins
and minerals, so inexpensive, and so generally beneficial that
it is a wonder that they are not more liberally provided. Diamond
V mills sell their yeast pretty much nationwide as a cattle feed
supplement, in 50-lb. bags, very inexpensively.
Diamond V is a high-protein feed (14% crude protein
with 2.5% crude fat and 8% crude fiber) made up of yeast grown
and dormatized on yellow corn meal, soybean meal, corn by-products,
cane molasses, wheat middlings, wheat bran, wheat germ, and rye
middlings. You may have noted in reading the B-vitamin descriptions
that time and time again, yeast is referred to as the best source.
Diamond V yeast culture contains enzymes that help digest carbohydrates,
assist in the splitting of feed proteins, reduces fiber to simpler
carbohydrate and assists with the changing of fats and oils in
feeds to more digestible compounds. It slows digestion so that
the food eaten is available for a longer period of time. It will
raise butterfat levels, and one of its most valuable assets is
the prevention of bloat–it's complement of lactic ferments
and enzymes get the rumen 'cooking' at peak efficiency.
The analysis per pound:
Vitamin A 380 USP units Calcium .187%
Vitamin E 90 i.u. Phosphorus .620%
Vitamin B-1 13.2 mg. Potassium .950%
Vitamin B-2 11.2 mg. Sodium .444%
Niacin 75.3 mg. Magnesium .254%
Pantothenic Acid 22.6 mg. Sulfur .237%
Vitamin B-6 5.0 mg. Chlorine .084%
Choline 2,480.0 mg. Iron 53 mg/lb.
Folic acid 685.0 mcg. Zinc 17 mg/lb.
Biotin 62.0 mcg. Manganese 14 mg/lb.
Vitamin B-12 .48 mcg. Copper 8.9 mg/lb.
Selenium .14 mg/lb. Cobalt .14 mg/lb.
Diamond V can be fed free-choice, but best is to mix it in
the feed; it increases the palatability of concentrate rations
and goats will often eat yeasts when they won't eat otherwise.
We consider it an essential feed for goats; its high phosphorus
level helps balance calcium-rich alfalfa, beet pulp and kelp meal.
1 or more ounces per feeding is suggested.
Brewer's Yeast on the other hand lacks the live
cells. It is even higher in potency of vitamins and minerals,
and is 40% protein; but it must be fed with caution as like any
high-protein feed, it can bloat animals! It should never be fed
free-choice; but we add 1 tsp. to 1 tbsp. on top of each concentrate
feeding along with the Diamond V; goats love them both. Brewer's
yeast is available in health food stores.
The Free-Choice Mineral FeederMaterials RequiredA Front boards 8 required 3/4" x 4-1/4" x 18"
G partitions 11 required 3/4" x 3" x 6"
B cleats 4 required 3/4" x 2" x 48" H tray bottom
1 required 3/4" x 7-1/2" x 48"
C bottom board 1 required 3/4" x 9" x 48" J
end boards 2 required 3/4" x 10-1/2 x 24"
D back boards 3 required 3/4" x 4" x 24" K footrest
ends 2 required 3/4" x 6" x 12"
E top board 2 required 3/4" x 6-1/2" x 48" L
footrest board 1 required 3/4" x 6 x 49-1/2"
F tray sides 2 required 3/4" x 3" x 48"
Note: in constructing the feeder, one of the ten compartments
is 3-3/4" wide; the other nine are 4" wide, and the
tray then comes out to an even 4 feet long overall. A piece of
plywood can be used for the top. For dairy bucks, make the head
holes 9" in diameter. Mount the finished feeder at whatever
height seems comfortable for your adult goats; usually an inch
or so above the tail is satisfactory, and helps prevent accidental
soiling. Kids will put their front feet on the foot board and
reach in through the keyholes, though tiny kids can benefit from
a couple of concrete blocks placed on the ground in front of the
feeder.
The sources of supply for the supplements we recommend and
use ourselves, are:
(1) Innovators Route #4 Box 192, Brenham, Texas 77833;
phone 409 830-5444, sells Kelp meal and some other products based
on it. At present they are the most reasonably priced supplier
of kelp meal in the US known to us; many feed stores and agricultural
distributors sell small quantities packaged for horses at much
higher prices.
(2) Diamond Mills Inc. Cedar Rapids, Iowa 52407 makes
and distributes their Diamond V Yeast Culture. They do not sell
direct, but feed stores can get the product.
(3) The Grain and Salt Society P.O. Box DD, Magalia,
California 95954; phone 916 872-5800, or 1-800-TOP SALT. These
are very fine people genuinely interested in health and nutrition;
a pleasure to work with.
