The
Feeding Of Goatsby
Robert L. JohnsonThis
article will address the subject of dairy goats primarily, since
their nutritional needs are more critical, though the basics discussed
here also apply to all other goat breeds–Pygmy, Nigerian
Dwarf, Angora, etc.
If nutritionists could engrave on the brow
of every animal raiser 'You Are What
You Eat'–much
animal and human disease could be prevented. The arguments about
heredity versus environment have gone on for years–but if
we consider feeding to be an environmental factor, we must realize
that it affects heredity also, for the nutrition of the sire and
dam are important–faulty nutrition there can be just as detrimental
to the growing fetus as it can later in life to the kid, and to
the adult animal it becomes.
Humans are monogastric, a term scientists use
to mean 'single-stomached.' In humans, the food we eat is directly
digested and absorbed in our stomach and intestines. Thus there
is a rapid cause-and-effect relationship in the way food affects
us. Drink too much coffee and shortly thereafter you get the 'jitters'–coffee
nerves. Eat a heavy meal with a rich, sweet dessert and you get
that stuffy feeling caused by your stomach trying to process a
food overload. We have no mechanism for storage of large quantities
of food. The goat, on the other hand, is an herbivore, a ruminant
with four separate 'stomachs', and the mechanism it has for processing
its food is quite different from that of carnivores (meat-eaters)
and omnivores (meat and vegetable eaters, including people.)
When you feed a goat, you are feeding bacteria,
and the bacteria in turn feed the goat. Ruminants are so named
because everything the goat eats goes first to the rumen, a large
pouch that is a combination storage tank and mix-ing vat. In the
rumen, bacteria break down, and consume the huge variety of foodstuffs
that the goat ingests, many of which are very high in cellulose,
and convert them to a nutrient 'soup' that is further processed
in the other three stomachs–the reticulum, omasum and abomasum.
The goat's 4th or last stomach in the processing sequence is the
abomasum, and it functions like the human stomach or the simple
stomach of the carnivore.
The rumen in an adult dairy goat holds several
gallons; it can hold a very large supply of roughage, browse,
forage plants, and grain, and the goat is therefore equipped by
nature to take in a considerable quantity of food at one time,
and then later reprocess it by bringing up and chewing the cud.
This has evolved over tens of thousands of years–it is a
defense mechanism; for the wild goat can quickly fill its rumen
at opportune times, when there are no predators about, and then
retreat to a safe area and chew its cud at its leisure.
So remember, you're feeding bacteria, when
you feed your goats. There are other considerations:
(1) No goat is native to the U.S. It has been
here since the early Dutch settlers in the 1600's, but 300 years
is only a tiny fraction of the time required for a species to
evolve and adapt to a new habitat. The only native goat-like animals
we have are not true goats–the Bighorn sheep, and the so-called
Rocky Mountain goats which are really goat-antelopes. These are
far-northwestern animals; the point is that no goat is
native to the majority of the United States, especially the humid
southeast, where soils are thin and acid, and their mineral content
quite low.
(2) For tens of thousands of years, no goats
ate grain or concentrates. They subsisted solely on plant matter–browse,
brush, grasses, weeds, trees and bushes. Through natural selection
they evolved the large rumen capacity and ability to utilize a
greater variety of plants than any other animal (the goat can
safely consume and utilize 450 of the 540 native American trees,
shrubs, and grasses.) They evolved the ability to produce just
enough milk to raise a kid or two to an early weaning age. Most
of the food a wild goat eats, after basic maintenance, goes into
providing energy for long-distance foraging, flight to escape
from predators, and to making horns–their social mechanism–and
hair, for protection from the extremes of weather.
Then along came mankind, who started tampering
with this natural lifestyle of goats. For centuries he did little
to change this–early man herded them in flocks, leading them
from pasture to pasture over large land areas, taking such excess
milk that was available, culling some kids and old animals for
meat and skins. Then recently in terms of evolutionary time, Man
began to make more major changes. We learned to grow grains for
feeding to animals. We learned to breed selectively, and then
to feed for the greater production. We penned the goats in stalls
and small pastures for convenience in handling them and for feeding
them concentrated rations. These are very recent developments–today
in many parts of the world, goats are still fed no grains or concentrates,
and are herded so they can forage for their food. We must remember,
however, that the goat is a creature that is adapted by centuries
of evolution to long-distance foraging, diverting of surplus rations
into kid, hair and horn production, and the con-suming of the
bulk of its diet in plant matter. We have taken the goat away
from its natural regime, which means that the proper feeding of
high-production dairy goats is now totally in our hands, and thus
their life and health.
Composition Of FeedsAll feeds provide one or more of the following:
Protein, Energy (carbohydrates and fats), Vitamins, Minerals,
and Water. All of these are necessary to life; to the survival
of the individual cells that make up the animal. No animal, nor
man, can live without a supply of all of these; the problem is
to find the quantity and the balance that is needed. So let's
first look at these individually:
A–Protein.
The building-blocks of the cells, protein is necessary for growth,
for repair, and for production. Hair, horns, and hooves (fingernails)
are mostly protein; and the manufacture of milk requires protein.
Protein if supplied in excess can be used for energy–work
and fattening–but usually this excess is not provided. In
feeds, protein is always in shortest supply and is the most expensive
component of purchased feeds.
B–Energy
(Carbohydrate and fat) is the major component of feeds–and
the major need of animals. All life requires energy–to
maintain body heat, metabolism, and allow growth plus fattening,
as well as to provide the 'fuel' for work. (draft animals, for
instance.) In cold weather, energy requirements go up. In human
diets, carbohydrates and fats are discussed separately, but in
animal diets, usually the two are combined and referred to as
Energy.
C–Vitamins
are nutrients needed in minute amounts, but these are critical,
for they function as catalysts and regulators in critical bodily
processes.
D–Minerals
function in the same way, although in addition, some of them like
calcium and phosphorus are the main components of bones. Iron
and copper must be present to form red blood cells. Cobalt must
be present to allow the animal to make one of the essential B-vitamins
(B-12). They are closely linked to vitamins in many functions.
E–Water
You may not think of this as a nutrient–but life cannot exist
without it. The body of a doe weighing 160 lbs. is made up of
over 55% water–88 lbs. This does not count the amount in
her milk (which is mostly water). Water has so many functions
in the body that we could devote the rest of this article just
talking about them–it transports the minerals, vitamins,
and amino acids throughout the system, carries waste materials
out of the body, etc., etc.
F–Oxygen
is listed as a nutrient, for actually it is–fortunately,
you don't have to worry about how much is in the feed. But just
as you can't build a fire without it, so the manufacture of bodily
heat is also a process of combustion.
Functions Of NutrientsWhat does the animal do with its nutrients?
We can best think of the uses of feeds by putting them into five
categories: (l) Maintenance (2) Growth (3) Reproduction
(4) Production, and (5) Regulation.
(1) Maintenance.
Animals, like people, are never idle. They use nutrients every
minute of every hour of every day of their lives, whether they
are resting or asleep, or hard at work making milk, pulling a
plow or running a race. Maintenance is the combination of nutrients
needed by an animal to keep its body functioning without any gain
or loss in weight, and no production activity. These nutrients
must be in balance. Even at a minimum level, all proteins, carbohydrates,
fats, vitamins, minerals, water & oxygen must be present.
An animal asleep with bodily processes at a minimum has what is
called the Basal Maintenance Requirement. Just standing up takes
9% more nutrients than lying down. There are only a very few times
in its life that a goat would actually need this minimum number
of nutrients–it is approached by bucks not in service, and
mature, dry, non-pregnant does. But many factors affect the BMR
- weather, stress, exercise, body size, temperament, production
level (high-producing does have higher maintenance needs even
when not producing), etc.
(2) Growth is
influenced mainly by nutrient intake. Dairy goat breeders that
breed does every year starting with yearlings or younger does
are putting tremendous demands on them that can only be met by
adequate nutrient intake–the demands of growth coupled with
development of a fetus and the laying up of a reserve for lactation.
Dairy goats should double their birth weight in 22 days–and
should reach 50% of their adult weight in 6 months–if they
do not achieve that, we must look to inadequate nutrition as well
as parasitism and/or disease problems. Larger goat breeds grow
more rapidly than smaller ones and have a higher nutrient requirement.
There is such a thing as compensatory growth–that is, after
a period of illness or reduced nutrition, animals may compensate
by a period of very efficient growth and gain–a surge of
growth. However–growth does not mean fattening! Memorize
this: build bone, not tissue in the kids. Breeders–if
you want long-lived high-producing animals–don't over-grain
kids!
(3) Reproduction.
Liberal feeding makes for early sexual maturity. Underfeeding
cause temporary sterility. Excessive thinness results in low birth
weights and weak young, as well as poor lactation. Low energy
levels during the last trimester of pregnancy have been shown
to have adverse effects on cycling and rebreeding next season–fewer
females will come in heat. Low protein causes the same thing,
as does low phosphorus, iodine and vitamin A.
(4) Production.
Lactation is really a by-product of the reproductive process.
Production requirements are much more rigorous than those for
maintenance or pregnancy. A doe in milk is doing very hard work,
even if it is not obvious. Milking does, more than cattle, have
the ability to store up reserves for lactation in advance of kidding–but
if they do not store these reserves, production will be adversely
affected. Nature decrees that the mother will be sacrificed to
the benefit of the young. That is, she will milk 'off her back'
and draw from her own bones and tissues to further the species,
and she can be stunted, even sicken and die of metabolic diseases
(ketosis, milk fever, etc.) if she is really underfed. Remember–a
heavy-milking doe is doing harder work than a horse running a
race–the latter gets to rest between races; the doe does
not! During early lactation, there is NO WAY a high-producing
doe can eat enough to match her production, and even those that
have been very well fed will milk off their bones for a period
of time. They require extra nutrition later when milk production
may have tapered off, to replace their reserves.
(5) Regulation
refers to the needs for vitamins, minerals and other micro nutrients
which play a great number of roles in the body mechanism, many
of which are poorly understood, or not understood yet. Iodine,
for instance, controls the activity of the thyroid gland which
in turn controls many bodily functions, including the production
of milk. (The dairy goat has been called a 'glandular' animal.)
Vitamin A is essential for maintenance of the epithelial tissues,
which are the body's first line of defense against the introduction
of disease-causing bacteria and pathogens–and for the phenomenon
of vision, to mention just two things.
Utilization Of NutrientsIn dealing with animal feeds, you'll encounter
the term TDN, or Total Digestible Nutrients. This is the way that
the nutrient values of feedstuffs are given and compared commercially.
TDN is the sum of the digestible protein, (or 70% of the crude
protein,) digestible fibre, nitrogen-free extract, and fat x 2.25.
Let's first look at how feed energy is used.
No system is 100% efficient, whether it's an
electric motor, a gasoline engine, or a living animal; there are
energy losses along the way. The engine in your car is actually
only about 15% efficient–that is, of the total energy con-tained
in the gasoline, only about 15% of it is available at the rear
wheels–due to losses in the engine (heat, friction, auxiliaries
needed to make the car run, such as fuel pump, generator, fan
& water pump, etc.) plus losses in the transmission system,
friction, the slippage of the tires on the road. Thus it is with
animals. The same is true of proteins–the sacks of feed you
see in the store all list crude protein content, but they
do not–they couldn't–list the amount of protein that
is usable by the animal. We talk of the biological value
of proteins–that is, the amount of the protein that is actually
usable, after digestion, and every breed, every individual
animal, is different. If the amino acids in protein match those
needed by the specific animal, the biological value is high–but
a protein can be high in some or many amino acids that are not
usable; thus its biological value is low and the surplus will
be excreted by the kidneys. Animal proteins are high in biological
value; much higher than plant proteins, (on a scale of 1 to 100,
eggs are 94, milk is 85, whole corn 60, navy beans, cooked, 38,
etc.) but they are really not digestible by goats.
When you look at sacks of animal feeds you
will note that they will list three things:
Crude Protein
Crude Fat
Crude Fibre
The higher the fibre, the less digestible the ration in terms
of usable protein and energy, although for goats (and all ruminants)
some fibre is essential. The higher the fat–the higher the
energy. Next; the ingredients are listed in order of their quantity
in the feed, so if corn is the first thing listed, there is more
corn than anything else in the feed, and so on. At the bottom
of the list of ingredients you will see the vitamins and minerals
(if present) listed.
Minerals: 18
are known to be required by animals, divided into two types: those
that large amounts are needed-called MACRO or MAJOR–and those
needed in only tiny amounts, called MICRO or TRACE. Remember that
the trace or micro minerals are not any less important–just
that they are required in smaller amounts. They are:
Major or Macro Minerals Trace or Micro Minerals
Sodium (Na)
Chromium (Cr)
Selenium (Se)
Chlorine (Cl)
Cobalt (Co)
Silicon (Si)
Calcium (Ca)
Copper (Cu)
Zinc (Zn)
Phosphorus (P)
Iodine (I)
Magnesium (Mg)
Iron (Fe)
Potassium (K)
Manganese (Mn)
Sulfur (S)
Molybdenum (Mo)
Calcium accounts for 49% of the total mineral
composition and requirement of the body, and Phosphorus 27%; all
the rest together account for only 24%.
Minerals have many functions, not all of which are known, but
it is known that they:
(1) Give rigidity to the skeleton
(2) Serve as components of the organic compounds that make up
muscles, organs, blood cells, etc.
(3) Activate enzyme systems
(4) Control fluid balance & excretion
(5) Regulate acid-alkali balance
(6) Control the tone, or 'irritability' of nerves and muscles
(7) Work in relationships with the vitamins
Actually there are an additional 50 minerals
that are believed to be needed in extremely minute amounts.
Most of these are found in plant foods, though there is great
variation according to plant, stage of growth, composition of
the soil and water, etc. Increasingly, we are coming to understand
why the majority of the sheep and goat families come from mountainous
lands in Europe and Asia - their soils and water are much higher
in mineral content, and so are the plants that take up these minerals.
Vitamins: 16
are known to be essential in animal nutrition. Others have been
identified and more are still being found, but their functions
are not all known. The known ones are:
(1) Fat-Soluble (2)
Water-Soluble
A (Carotene) B1-Thiamine
Choline
D
B2-Riboflavin Folic
acid
E (the tocopherols) B3-Niacin (old designation) Inositol
K
B6-Pyridoxine Pantothenic
Acid
B12
PABA
(Para-aminobenzoic acid)
Biotin C
(ascorbic acid)
The fat-soluble vitamins can be stored in the
liver and the supply drawn on over long periods, as much as 6
months or more; the water-soluble ones cannot, and must be replenished
daily. Vitamins are VERY potent substances; only tiny amounts
are needed and excesses of some few can be toxic–(vitamins
A and D, and some minerals.)
Now we get to a very important, if 'loaded,'
subject–the 'MDR' or Minimum Daily Requirement of an animal
(or a person) for each of the different vitamins and minerals.
The MDR is a statistical mean–an average, set up to give
basic guidelines to manufacturers and animal owners as to the
supplements that should be included in feeds. It does not apply
to every animal, or any given animal or human–all are individuals,
with a great range of differences in requirements for nutrients.
Goats are genetically endowed in a great variety of ways–some
are very efficient in absorption and utilization of nutrients,
others much less so. Different times of the year and different
periods of life bring great differences in requirements. Age lowers
absorption capabilities, and stress, growth, pregnancy, produc-tion,
bucks in rut, cold weather, all call for higher levels of all
nutrients. Minimum requirements are those that have been determined
to keep an animal alive and prevent the onset of obvious symptoms
of deficiency diseases. Many of the MDRs were determined years
ago, and much recent research into nutrition and the functions
of individual nutrients have indicated that the MDRs are woefully
inadequate. A diet that has just enough vitamin A in it to allow
a goat's night vision to function might be inadequate to protect
that same goat from an attack of bacteria.
A great number of animals are underfed in energy
a great deal of the year; this is probably the most common deficiency
next to protein, and usually accompanies protein deficiency. During
times of energy shortage, the body withdraws energy from its fat
reserves. Often the mobilized fat is not completely metabolized
and ketosis develops. Ketosis throws animals off feed and thus
starts a vicious cycle that aggravates the problem. Cold weather
increases energy requirements 20% or more. Protein deficiency
also depresses appetite.
FeedingBefore you design a feeding program you need
to consider several things:
(1) What do you expect from your goats? Do
you want high and constant production, kids every year, and don't
particularly care if the productive life of the goats is only
6-8 years? Do you want to concentrate on top-quality breeding
stock, and are you willing to let this take precedence over a
steady milk supply? Do you go in for showing, and want big, bright,
alert, healthy-looking animals that will catch the judges' eyes?
Do you want a small herd for family milk, where the animals are
all loved pets and you want them to live long and healthy lives
and don't care if they don't set the world on fire as far as milk
and show records are concerned? Each set of goals requires a some-what
different approach to feeding.
(2) What types of goats do you keep? In dairy
goats we have two distinct physiological types–the Swiss
breeds, (Alpine, Oberhasli, Saanen & Toggenburg) and the Desert
breeds, the Nubian and the LaMancha. Their basic requirements
are similar but their abilities to ingest, process and utilize
feedstuffs are somewhat different.
The Dairy Herd
requires a lot of goats that milk well with a minimum of individual
attention, which the busy dairyman can't afford to give. One must
standardize on a feeding program, pour high-quality grains and
roughages to the goats to get maximum production, and cull out
those that don't produce up to standard, or that are always plagued
with some problem.
The Breeding Herd
is built around a small nucleus of goats of top quality whose
kids pay their way. Most breeders feel they must show heavily
as well as advertising, and on such a regimen, the animals have
more opportunity to pick up diseases and are stressed more than
the dairy herd that stays on the farm eating and milking. Such
a herd should receive top-quality nutrition to assure a multiplicity
of healthy kids and good stress and disease resistance.
The Show Herd
must conform to the show season first and foremost. Big, growthy
kids are wanted by show time, as well as does that peak in production
at the same time. The show-goat owner must feed and breed accordingly.
Such kids will not live as long nor milk as well, as a result
of being fed much grain early in life to condition them. It is
a known fact that applies to all animals–fast early growth
leads to shorter lives.
The Family Goats
are often much-loved pets, and there are probably not a lot of
them in the herd. This is a situation where goats can be individually
bred and fed according to their needs. If the doe kids are not
really up to breeding size in the fall, as a result of the correct
feeding of little grain, much milk and browse for rumen development,
the owner doesn't worry about that; he carries them over to the
next year. They may be bred and kid every second year so that
they are not in the continual stress of heavy milking or pregnancy.
Such goats are likely to live and milk and kid for 12-14-16 years,
sometimes longer.
This is not to say that these approaches cannot
overlap to a considerable degree; in fact they usually do. Given
the time and money, a dairyman theoretically could individually
feed and supplement a herd of 100 or 500 goats, but in practice
this is not likely to work out unless the dairy is not required
to pay its way. There are many ways to feed goats, and obviously
there is not just one right way (thank goodness!) But since there
has been little research into the needs of dairy goats compared
with cows, horses, pigs, and even Angora goats; some of what has
been written about goat feeding is nonsense, a lot is myth, or
is based on practices that work for the person who wrote the article
or book, but that may not work elsewhere. The best research that
has been done indicates the following:
(1) The goat produces more milk than
the cow from the same quantity of nutrients.
(2) The goat uses less food for maintenance, but more
for digestion and metabolism than the cow. (In proportion to
body size, of course)
(3) Goats are extremely fastidious feeders. They require clean
water and feed.
(4) Goats have much higher requirements for minerals than the
cow. Their metabolism is higher, and their glandular systems
are larger in proportion.
(5) Goats can ingest and utilize a greater variety of forages
than any other ruminant. One of the reasons they have this ability
is to support their higher mineral and vitamin requirements.
Also, the digestibility of forages varies with age, cutting time,
fertilization, soil, etc.
(6) Goats require exercise. Appetite and production will be improved;
they are less successfully kept in total confine-ment than cows
are.
(7) The calcium-phosphorus ratio is important, and it should
not vary much more than 1.25 to 1. Alfalfa and other legumes
are high calcium; most concentrates (grains) arehigh phosphorus. A balance is required between
grains and forages.
(8) Goats require much more iodine than the cow.
(9) Unlike cows, goats cannot tolerate much urea, which is found
in many dairy feeds–beware.
(10) Goats lack the mechanisms to digest and assimilate animal
proteins very well. The amount of animal fats in dairy rations
should be very low. This is because of goats' faster throughput
of nutrients and higher metabolism.
(11) All grains–corn, oats, barley, millet, milo, rye, etc.-should
be flaked, crimped or rolled. This increases digest-ibility and
assimilation.
(12) Horse feeds should not be fed. They contain too much molasses,
are too low in fiber and protein, and too high in calcium.
RequirementsWhat does a good dairy goat need? First we
should ask–what is a good dairy goat? Well–despite the
many ads you see in the magazines for 3,000, 4000, 5000 lb. milkers–a
good practical dairy goat is one that will give a ton of
milk–2,000 lbs.–in a 305-day lactation. That is quite
a reasonable goal to shoot for; there are not really many goats
that will perform that well and meet our other requirements
for health, stamina, and long life. 2,000 lbs. of milk is an average
of 6.5 lbs./day. More likely, a doe will freshen at 8-9 lbs. and
drop off to 4 lbs. by the end of lactation. Don't let the ads
fool you –if you counted every goat advertised that milked
3000 pounds or more, you might tally about 100 or 200 goats–but
in 1989, 54,000 goats were registered by the ADGA alone.
As production increases above this amount,
more problems begin to appear. The doe will need to be very large;
and the feeding will become more of an art, as she walks a thin
line between acidosis and ketosis. The large mammary system in
full production is more prey to mastitis. The stress on the animal
is greater and thus the chance she will contract disease, or succumb
to parasites, increases. Which would you rather have–2,000
lbs. of really good milk from a trouble-free animal, or 3,000
lbs. of undrinkable, unsalable milk, coupled with worry, expense
for vet bills, three-times-daily milking, etc. from a goat that
you are always having to 'baby' and who is short-lived?
RationsDoes can consume 2.5-3 pounds of forages and/or
hay per 100 lbs. body weight, as an average–or 5-11% of body
weight of all dry feeds. Goats being ruminants, fibre is essential
in the diet; they cannot be fed all grains, like pigs can. Lack
of adequate fibre will depress butterfat and predispose to acidosis.
The dairy goat requires, for maintenance:
.9 lb. TDN per 100 lbs. body weight
.09 lb. digestible protein per 100 lbs. body weight
and for production:
3.25 lb. TDN per gallon of milk (.4 lb. per lb. of milk)
.5 lb. digestible protein per gallon of milk (.0625 lb. per lb.
of milk.)
Let's take a 150-lb. doe that is giving 8 lbs. (one gallon) of
milk of 3.5% butterfat. Her requirements are:
for maintenance: l.5 x .9 = 1.35 lbs. TDN
and l.5 x .09 = .135 lbs. protein
for production: 3.25 lbs. TDN
and .5 lbs. protein
for a total of 4.6 lbs. TDN and .635 lbs. protein
On poor grass hay of low nutrient content,
where the goat gets its nutrients from concentrates, it would
need about 4 pounds of a concentrate ration with 16% digestible
protein–not to be confused with 16% crude protein.
A Nubian doe giving the same quantity of milk at 6.5% butterfat
would need 25% to 50% more protein and TDN; such a doe might eat
5 to 6 pounds of grain per day. As the hay quality improves in
TDN and protein, decrease the amount of grain.
For most of us, using the above data as a rough
check on how well we are feeding our goats is the practical procedure,
and then following up on the animals' performance according to
some guidelines, including:
(A) Don't attempt to judge flesh or degree
of fatness by the width of the goat. That bulge you see may be
a full rumen (and it can be full of poor quality forage as well
as of top-flight alfalfa hay) or kids, water, or gas, or all four.
Feel the goat's chest, the top of its backbone at the hips and
the rump slope. A thin quilt of fat over these areas is desirable–so
you can still feel bone. Goats can starve to death on rumens full
of indigestible forage–the coarser the forage and the poorer
the quality, the more protein required to process it. Shortages
of protein limit milk production, and lower the goat's ability
to utilize the forage it eats.
(B) One good system is challenge-feeding. You
increase the quantity of the goat's grain until milk production
peaks, then back off 1/2-pound and feed at that level until again,
milk production declines, which will be several months later in
a good doe. Meanwhile you feel periodically for extra fatness.
If the goat is putting on excess flesh on the quantity you are
feeding, try increasing the protein content of her ration
and decreasing the energy or total grain fed. (Add soy
bean meal and/or the other oil meals to her ration.)
(C) If your doe has gotten fat (no milking
animal should be fat) don't decrease her grain drastically or
remove it; feed her a wet and bulky diet. This will direct
liquids to the udder and forces her to milk some off her back.
Try various systems of getting her to increase her consumption
of water. Add a little salt to her feed. Try feeding wet
feeds such as cooked cereals. Offer water warm. Feed her a proportion
of wet crops such as carrots, beets, kale, apples, pears, citrus,
etc. Keep her supplied with protein. If you were feeding
16% dairy feed, try switching to 18, 20, even 24% and feeding
a much smaller quantity of it, while giving her a bulky, sappy
diet. Satisfy her appetite with high-roughage, low-energy feeds
like beet pulp.
(D) If you have a doe that produces heavily
and goes out of condition, becoming thin as her lactation peaks,
you need to increase both the quantity of feed, and the energy
in her feed. You can decrease the protein content of her rations
(and give her more grain) by adding corn and oats. Change to a
top-quality alfalfa fed free-choice and alternate that with lower-TDN
hays. Many such goats are the small, very dairy-type does that
have the will to milk but don't have the body capacity to sustain
their lactation. Such does are at risk; it is best to dry them
off, and feed them heavily all throughout the dry period, to build
them up. Make sure they are eating well, but not fat, before re-breeding.
(E) Many breeders dry up a goat that is not
producing up to expectations soon after kidding, and breed her
back quickly. This is very poor practice. First, this encourages
the doe to go dry early in later lactations. Second, there are
reasons why she is not doing well, which should be sought–it
might be that the breeding didn't work out as hoped, but it could
be any number of other things including shortages of some vitamins
or minerals, or a subclinical illness. A goat that won't eat may
be suffering from a painful mouth due to misplaced or damaged
teeth–it's not always illness. Especially, one should not
hastily dry up first fresheners. Even if they give only a squirt
or two at a milking, it is good practice (if frustrating) to keep
on milking them through their first 300-day lactation.
We Americans are impatient people, but few
other fields require the patience that animal breeding does. Sure,
it is easier to dry up a poor producer, breed her back and hope,
rather than take the time and effort to try a lot of feeds and
feed combinations to see what her individual requirements are.
It's easier to buy grain and hay and feed all the goats the same
way, changing only the quantity of grain you feed each goat, than
to try keeping on hand various feeds and mixing them while feeding
each animal, for top performance. It's easier to feed more grain
and skimp on the hay, which due to its bulk is harder to handle
and store. But in goats, the milking doe should get her production
ration from hay and her maintenance ration from grain–not
the other way around. This is feed-ing in sympathy with the evolution
of the goat–with its natural characteristics. The easy way
out is never the road to success in animal husbandry and breeding.
Dairy cow formulations should not be used–they
indicate 1/3 ration in roughages and 2/3 in concentrates which
are too low in minerals and roughages for goats.
As to feeding practice: we'll start with the
minimum requirements and move on up.
It is definitely possible to feed goats on
nothing more than browse (the diet of the wild goat) with access
to water and salt. (No ruminant can live without salt.) Many thousands
of goats are so kept, and unfortunately there are few records
on such animals, to determine how long they lived, what number
of kids they had and what number they raised, how they milked,
etc. The closer that goats live to wild (natural) conditions,
the more natural selection is operative; i.e. the weak will die
off and the strong survive, and eventually, one would wind up
with a herd of very rugged goats, though they would be poor producers
without selection and feeding for production. Many such goats
live without much shelter, and we have known of some that stayed
out in the rain as happily as cattle, at least in summer, believe
it or not! Under these conditions the life, the health and fecundity
would depend solely on the quality and quantity of the forage
the goats had access to. In this country, many brush goats are
kept this way.
Owners of such goats would do far better by
them with a few additions, such as the provision of a shelter
for incle-ment weather, loose salt, baking soda and loose trace
mineral mix, and a bit of hay, particularly in winter and spring.
To assure high birth rates and survival of the greatest number
of kids, giving a bit of grain during the last two months of pregnancy;
when the does begin to "show", and for a month after
kidding, would be quite beneficial.
Dairy goat nutrient requirements are considerably
higher, since they are bred for producing milk for more than the
month or so that the wild goat nurses its young. Given the land
area of sufficient quality to provide a selection of forage plants
including legumes, they can be kept on a diet of browse with only
a little supplemental grain. Some dairies do this successfully;
the does only get grain at the end of pregnancy and early lactation.
You don't get earth-shaking milk records this way, but this is
real goat-farming–as opposed to goat fancying,
which is what most of us do. Given suitable soil, one can cultivate
crops for goats to graze–alfalfa, rape, kale, clover, sunflowers,
etc.-and let them graze the crop edges on running tethers, to
prevent their trampling and soiling the whole crop. Most goat
breeders do not have land or time for such techniques–the
majority of us keep our dairy goats on limited land where they
receive most of their feed from dry forages (hay) and concentrates.
Nutritional SupplementationNow we enter an area of controversy. There
is an old saying that one should not discuss religion, politics,
and health foods with anyone except friends that share the same
views. I find it hard to understand, in a country where money
is the god, why anyone or any agency of government would try to
prevent the purchase of simple vitamins and minerals, (the government
constantly tries to get them on a prescription-only basis) most
of which are absolutely non-toxic and the few that are, are toxic
only in really huge amounts. Yet thousands of people die annually
from common over-the-counter drugs, to say nothing of alcohol.
The MDR's for people and animals are woefully inade-quate, and
goat MDR's have not even been established yet. Therefore feed
manufacturers can include whatever ingredients they want, as long
as they are listed in order. It is not required to list vitamin
and mineral potencies. They can say they have put in vitamin A,
and may have added 10 units instead of 20,000 per pound–and
thus give you a false sense of security. In animal and human nutrition,
increasing evidence is accumulating that the many different roles
that vitamins and minerals play are crucial to health, productivity,
disease resistance, and long life.
Animal illness takes three basic forms–Metabolic
diseases, usually caused by improper feeding; Infectious
diseases–bacteria, viruses, etc.–and Accidentsand Injuries.
The Golden Rule is–establish a high-quality
basic plane of nutrition. If all known nutrients are provided
in adequate, or slightly excess quantity, you are assured that
metabolic diseases will be virtually eliminated from your herd;
the goats' increased resistance will help them build immunity
to infectious diseases, and they will heal from accidents and
injuries much faster. Here's a quick review of the metabolic diseases,
since nutrition is their underlying cause:
Acidosis - too
much concentrate; too rapid a change in feeds. The rumen becomes
acid. Be sure goats have free access to baking soda.
Anemia is caused by a nutritional shortage of iron, copper,
cobalt, and/or some vitamins.
Aphosphorsis or Osteomalacia - too little phosphorus in
the ration. Goats chew on wood, bones, dirt, rags, etc. Stiff
joints–milk fever–breeding problems.
Bloat can be a killer - the rumen stops or slows - prevent
by feeding live-cell yeast, minimizing wet legumes; always feed
dry hay before turning goats out on sappy or wet pastures.
Enterotoxemia - 'overeating disease'–vaccinate; avoid
overfeeding of concentrates and/or rapid change in feed type
or quantity. Minimize stress.
Founder or laminitis the result of too much grain, too
much protein, and/or too rapid a change in feeds.
Goiter insufficient iodine–big neck, reproductive
failure–poor production–weak, hairless kids. Use iodized
salt; extra organic iodine for does in milk.
Grass Tetany is magnesium deficiency. It mainly
occurs in spring; new grass is low in magnesium. Feed a complete
mineral mix that includes magnesium.
Ketosis is poorly understood; but mainly a lack of energy.
Grain-feed even fat does the last 6 weeks of kidding, increasing
the energy (corn, etc.) in the ration and decreasing the protein.
Especially important for does carrying multiple kids. C-sections
may be necessary to save the kids–prognosis is poor when
the doe goes down.
Manganese deficiency - kids born with stiff or curved
necks, bowed front legs. Feed a complete mineral mix.
Milk fever - too much calcium in the diet prior
to kidding. Limit the feeding of alfalfa hay and beet pulp the
last two weeks of pregnancy; increase the food yeasts.
Molybdenum toxicity - scours–black hair turns brown
- interferes with copper synthesis.
Nitrate poisoning -forages of heavily fertilizedgrain and hay crops; stressed crops (droughts). A quick
diagnosis; fresh blood turns brown - the vet can give
methylene blue IV, but yeasts help prevent.
Polioencephalomalacia - sudden death on high feed; animals
push their heads against objects due to headache. Give thiamin
(vitamin B-1) IV/IM.
Rickets is caused by a vitamin D deficiency.
Salt deficiency is caused by use of blocks. Loss
of appetite–retarded growth–rough coat–poor production;
then a sudden exposure to salt can cause poisoning.
Salt sick is a misnomer; cobalt deficiency exhibits
the same symptoms.
Selenium poisoning - no known treatment - loss of hair–hooves
slough off! This takes a great excess of selenium and is primarily
a western problem. Protein helps prevent; vitamin C drenches
might save the animal.
White Muscle disease is the opposite–a lack
of selenium & vitamin E. Give Bo-Se shots only for a goat
that needs radical treatment; feeding yeasts is better.
Sweet Clover disease is caused by moldy
clover; it destroys vitamin K causing internal hemorrhage.
Urinary calculi is caused by too much phosphorus
in rations for bucks. Be sure bucks always have clean water and
salt available. Ammonium chloride in water will help prevent,
and cure. Bucks' overall dietary should provide a calcium/phosphorus
ratio of at least 1.25 to 1; 1.5 to 1 is better. Feed alfalfa
hay to bucks, occasionally.
POISONINGS are also metabolic diseases. This
is not an article on veterinary practice and there are far too
many to go into here. Successful treatment depends on knowing
what the poison is! Some are acute-laurel, rhododendron, wild
cherry. Some are mild–salt, privet, fluorine, some molds;
some are cumulative–lead, urea, etc. These are the hardest
to find, for the goat may be consuming a little over a long period
of time and then one day it hits them. You should (1) call the
vet; (2) look for the poison source (3) give massive doses by
injection of vitamins C and the B-complex while waiting.
Assumptions(1) Most rations do not have adequate levels
of vitamin A, D, iodine, and E for dairy goats.
(2) Most rations have no live-cell yeasts included.
(3) Most rations do not have enough, or the right kind, of selenium
included.
(4) Most rations have no baking soda included.
(5) Most rations do not have enough minerals included; minerals
should not be in rations, but must be fed separately
(6) Most rations have too much molasses.
Do not use salt licks. They are OK for cattle–not
for goats. Many are too hard; the goats can't get enough, and
may break their teeth trying; mainly, though, they spend too much
unproductive time at the blocks when they should be out grazing
or cudding. Some are poisonous when they get wet; goats may urinate
on them and stop using them.
RulesOf ThumbGrains are high-energy,
high-phosphorus.
Alfalfa hay is usually very high-calcium and high-protein,
high energy. Other legume hays are fairly balanced in
C/P, medium in energy, medium in protein.
Grass hays are low in minerals, energy, and protein.
Seeds, oil meals (soybean meal, sunflower seeds, cottonseed meal,
etc.) are very high in protein and phosphorus
Therefore if you feed alfalfa hay, you need
to feed grains and/or additional sources of the phosphorus minerals
such as monosodium phosphate, dicalcium phosphate, etc. If you
feed other legume hays, also feed more dicalcium phosphate; monosodium
phosphate won't be needed. If you feed grass hays, you need considerably
more high-energy, high-protein feeds, and to supply various mineral
supplements in loose form. BUT–don't you balance the mineral
ration–let the goats do it; they are much wiser. Your task
is to give them the opportunity by providing the variety of feeds
and supplements that will supply all the nutrients–protein,
energy, roughage, vitamins, minerals, and water.
In winter, you can help warm the goats by supplying
more energy feeds such as corn and oats. Mainly, however, they
get heat from the bacterial fermentation in their rumens. They
need plenty of real roughages–tree bark, dry leaves,
poor-quality hay, even straw. If you give a goat a big bowl full
of high-protein feeds on a cold winter night, you are actuallychilling the goat; still more energy is needed to digest
the meal, and goats can get pneumonia.
Watch a goat browse–it doesn't (unless
it's starved) stay on one plant all the time–it takes a bite
of this, a bite of that, and back to the first again. Goats, because
of the tremendous number of different forages they can eat, have
evolved the mechanism to select for their needs–let them
do it.
The Final Word–A Selected RegimenHow could we best keep and feed our dairy goats?
Well, the theoretical ideal would be to have them on several hundred
acres of land that included both a river bottom on rich soil,
on which you grow a variety of nutritious crops such as alfalfa,
clover, oats, etc. for them, and also a high mountain pasture
on which grew pine trees & other conifers, and hardwood trees
including sweet gum, dogwood, maple, apple, hickory and ash, and
a great variety of 'weeds' such as burnet, chicory, dandelion,
yarrow, kudzu, blackberry, etc. On this land, goats would roam
freely. Kids would get little or no grain–until they were
a month away from breeding and only a little until they were 2
months away from kidding–and milkers very little, according
to production. All free-choice minerals and vitamins would be
available, and the goats would have access to pure spring water.
They probably wouldn't have to be wormed, certainly not very often.
This is dreaming! Failing such an ideal situation,
what we want to do is to try to approach this as closely as possible
with the resources we have. Here's the drill:
(1) Feed your does and bucks a good 16% dairy
ration, according to production; and keep on hand extra oats and
high-protein feeds like soybean meal and Calf Manna to supplement
with. Check them for fatness–if they gain, cut back on energy.
If milk production drops, increase protein. The smell of
ammonia in the barn is the first indication that you might be
giving too much protein; increase roughages.
(2) Alfalfa hay is made for high-producing
dairy goats, but it is not the only hay that will work for them.
It is high in protein, so less grain is called for. But whatever
hay you feed, remember two things: (1) Fescue hay is toxic at
certain growth stages, and is very low and unbalanced in nutrients
for goats, and should not be fed, and (2) never feed any MOLDY
hay, especially moldy clover. Hay should be supplied free-choice,
available at all times. The only exception to this would be if
you have a 4,000-lb. milker and you're trying for Top Ten; then
you may have to restrict hay consumption to get her to eat more
grain; but this is something to do only when absolutely necessary.
Desert breeds can eat more grain than Swiss breeds as a rule;
their deeper bodies are adapted to concentrate feeding while Swiss
breeds have larger spring of rib and rumen capacity for processing
larger amounts of forages.
(3) If you turn goats out to browse, be sure
they have some grass hay in them first, especially in spring when
pastures are lush and wet.
(4) Make an effort to have some pine trees
or pine logs, branches, etc. lying on the ground in the pens where
the goats can nibble the bark off of them.
(5) Get or make a 5-compartment mineral feeder.
Put in it and have available at all times, free-choice:
Salt–loose salt, iodized, from the grocery,
to which you add extra EDDI (organic iodine) for heavy-milking
does
Baking soda. Grain increases rumen acid, and
buffering is required.
A complete mineral mix with no flavoring agents
added
Monosodium phosphate or Dicalcium phosphate
Kelp meal
(6) To every grain feeding add:
Some live-cell yeast; a tablespoon or so,
A pinch of Brewer's yeast (level tsp. or less),
100 units of vitamin E,
A small handful of beet pulp, dried.
(7) Watch their appetites–if some go wild
over the live-cell yeast, give them more; they will not overeat
on these except Brewer's yeast which can bloat, if given in large
amounts at one feeding.
(8) Once a week or so, fill the 4th compartment
in the feeder (AFTER feeding and milking) with live-cell yeast.
Watch to be sure one or two bossy does don't get it all.
(9) For bucks, a 3-compartment mineral feeder
will be adequate, with salt, soda, trace minerals, or kelp.
(10) In the drinking water once or twice a
day, add a couple tablespoons of apple cider vinegar and a bit
of vitamin C. The maintenance dose is 1/4 tsp. of C per gallon.
After worming them, for two weeks also add 1/4 tsp. of an oral
iron/copper/cobalt to the water. Look at their eyes and
mucous membranes–this is an easy way to check for anemia.
If they are not really red, keep adding the iron/copper/cobalt
to their drinking water. Goats will accept the additives better
if the water is warmed, and will drink more, even in summertime.
(11) Do not be guided by just the gloss
of the hair coat alone. Nubians and LaManchas produce high butterfat
in their milk (Pygmies too) and they can get such a glossy look
that they appear to have been waxed! They can be dying of parasites
and still have glossy coats; hair takes a long time to change.
Swiss breeds rarely ever get such glossy coats; you look for 'highlights'
in the hair of healthy Alpines, Toggs, Saanens, and Oberhasli.
(12) Raising kids–volumes could be written
on this subject! Whether you raise them on their dams, or bottles,
pans or a combination of these–you want to build bone
and develop rumen capacity. This may sound hard to most
of you–but the longer they take to grow, assuming
all the while that growth is steady and progressing–and theless grain and more nutritious browse you feed them–the
more they will develop big, capacious rumens. There are decided
ad-vantages to raising kids on their dams; which includes the
convenience to you; (no washing, filling, heating bottles, etc.)
the fact that the kids get milk in the quantity they need just
when they need it; the lack of scouring problems, and the satisfaction
of the emotional needs of both dam and kids. It is true that such
kids if not given extra attention will become more 'wild' for
a period of time; this usually lasts only through kidhood and
by the breeding time the kid that knows you as something more
than a bringer of pain (injections) and unpleasant experiences
(worming, hoof-trimming, etc.) will accept you just as the rest
of the herd does. It is certainly true that hand-raised kids very
quickly transfer their affections to you; you become their 'dam.'
But whatever the regime you select for kids–remember that
they need six things: salt, minerals, soda, minerals, roughage,
and minerals. Give them milk for their basic nutrition. Tiny kids
should have access to very rough roughages–straw; dry, even
brown, hay; bark, anything to nibble on. At 3-4 weeks, start also
offering them the best, most nutritious hay you can find. Let
them get more and more of their nutrition from top-flight hay
and gradually decrease milk. Think of grain only as a carrier
for vitamin supplements and yeast–give them plenty of these
plus the minerals. Given this kind of a regimen, they don't need
a substantial grain ration until does are ready for breeding and
bucks to be used in service. Of course, the earlier you breed
them, the more grain they will have to have for growth as well
as fetus development and laying up reserves for milk production.
If the hay available to you is less than top-flight, you will
have to either increase their milk allowance or give them more
concentrates. Those of us used to seeing big growthy kids at shows
may be taken aback to see yearling goats that have been raised
on the milk-and-roughages regime and fed very little grain; they
may be smaller than the over-conditioned ones. But they will pay
you for your patience when they reach the milking parlor as 2-year-olds,
with big functioning rumens, and great eating and milking abilities.
How many of those big growthy kids that you see at shows reappear
later on as milking does making production records? Or live much
beyond 6-8 years? Not many.
Following Nature's lead as closely as possible
is sound practice, as long as it doesn't become blind adherence.
If you have no good browse for your goats, and can't get really
good-quality hay, obviously you will have to compensate, and modify
the milk-and-roughages regime for kids. In the wild, goats remain
parasite-free since they make use of large land areas as their
'home ranges' which they browse. In confinement, the rule is no
more than 1 goat per 1-1/2 acres, if the goats are to make their
living completely or primarily off the land. The wild doe may
be bred during her first fall, though not all are. But of her
kids, the strong would survive and the weak would perish; no one
would grain her or them, or baby them along, so natural selection
would favor those with good rumen development and high feed-conversion
efficiency anyway. The wild does would not, in nature, be selectively
bred for heavy or continuous milk production. If nursing kids
'ruins' a doe's udder, well, I personally don't want any doe with
an udder that poor! Show-goat breeders may remove the kids early
and bottle- or pan-feed them to 'save' a show udder; that is their
prerogative, and their goals are different. A healthy, practical,
trouble-free, utilitarian animal that milks well, lives a long
life and has few kidding and disease problems would be an asset
to anyone's home as a provider of that wonderful beverage, goat
milk, (which is fast becoming one of the few remaining natural,
balanced and nutritious foods available to us;) and raising that
type of animal is the main thrust of this article. Other goals
in goat-raising require some other methods, and so be it. But
whatever your aims are–
Good nutrition is sound insurance; it is your
fortress against disease; your fountain of long and happy life.
