The best management and health
program is accentuated with a nutritional program that matches
nutrient needs to production purposes. Goats are ruminants, which
means they can derive a substantial portion of nutrients from
plants. These hardy animals are selective browsers, eating a wide
variety of shrubs, woody plants, briars, and even weeds. The
availability of browse material (twigs, leaves, bushes, trees,
etc.) in goat pens and pastures appears to enhance contentment. Goats should be
fed good-quality forages along with the needed supplemental
nutrients to achieve desired goals, such as milk or meat
production or a well-conditioned show goat. The nutritional
program is dependent on type of goat (meat, milk, mohair/cashmere,
hobby) and production stage. For instance, due to milk production
needs lactating dairy goats have higher nutrient requirements than
dry or gestating does.
A quality Goat Power™ nutritional
program not only meets the goat’s requirements, but also minimizes
feed costs and maximizes profitability. The feeding program should
be based on goals of the owner, available feedstuffs, and goat
production stage. Basic nutrient requirements include water,
protein, energy (carbohydrates and fat), minerals, and vitamins.
Forage
Hay and/or pasture
(good-quality) can be used to provide primarily energy and some
protein. Since the goat is a ruminant, it needs to consume fiber
(forage) in the form of hay or pasture or browse to maintain rumen
health. For dairy goats, fiber is needed to maintain milk fat
test. Rarely, if ever, will forage alone provide all nutrients
needed by the goat. The need for supplemental feeding will be
dictated by type of goat (meat, milk, mohair/cashmere, hobby) and
production stage.
Water
The daily water
requirement for goats is affected by level of milk production,
environmental temperature, water content of feedstuffs consumed,
amount of exercise, and salt/mineral content of the diet. Fresh,
clean water should be available at all times. Goats are often more
reluctant than other species to drink foul-tasting water.
Low-quality and/or inadequate water supply will reduce feed intake
and lower goat performance.
Protein
Protein supplies amino
acids for protein synthesis and serves as a source of nitrogen for
rumen microorganisms. Inadequate amount of protein in the diet can
affect growth rate, milk production, reproduction, and disease
resistance. The amount of protein needed varies depending on
production stage. Young, fast-growing goats need a high level of
protein in the diet to deposit muscle mass, and lactating goats
need more protein for milk production. Mature goats can
effectively utilize non-protein nitrogen (NPN). Rumen
microorganisms need protein to effectively utilize forage.
Inadequate protein leads to inefficient utilization of forages and
reduces forage intake.
Energy
Energy deficiency in
goats reduces growth rate, delays puberty, reduces fertility, and
depresses milk production. Fiber, starch, and sugar from forages
and grains are the primary sources of energy in goat diets. Fat
can also be used to supply energy, but should be limited to no
more than 5% of the diet. Energy requirements are affected by body
size, growth, reproduction, and lactation. A deficiency of energy
will result in loss of body condition, poor growth, reduced
milking ability, and reduced reproductive performance. Obviously,
goats that consume more energy than needed become fat.
Minerals and Vitamins
Proper mineral and
vitamin supplementation make it possible for goats to achieve the
most economical gains possible from the forages and grain fed.
Minerals are needed in very small quantities, yet are critical
components of the overall nutritional package fed to goats and are
the backbone of successful commercial and show goat operations.
Minerals play a vital role in nutrient digestion, reproductive
performance, immune system function, and development of muscle,
bone, and teeth. The copper requirement of goats is frequently
questioned. The best information today indicates goats require
levels of of copper similar to cattle
requirements. Angora and Pygmy breeds have been reported to be
sensitive to copper supplementation.
Vitamins are needed in small
quantities for normal body processes. Vitamins A, D, and E are
likely to be the most deficient in the normal diets of goats.
Vitamin K and the B-complex vitamins are normally synthesized by
rumen microorganisms and are not considered essential for the
goat.
A diet consisting of forage, even
with added grain, will not provide the proper levels of minerals
and vitamins for optimum performance or production. The amounts
and ratios of certain minerals are also important in promoting the
health and productivity of goats. Due to the rumen microbial
population, a synergistic effect on digestive efficiency occurs
when protein and minerals are provided to ruminants. It is
suggested that goats be provided with
free-choice mineral-vitamin supplement to enhance digestive
efficiency.
Special Considerations
The ratio of calcium to
phosphorus should be maintained at approximately 2:1 to prevent
urinary calculi, especially in wethers (neutered bucks). While
sheep are copper sensitive, goats can tolerate more copper than
sheep and appear to need as much copper as cattle. The exception
may be Angora and Pygmy goats. Even though sufficient B-vitamins are
normally provided through rumen synthesis, goats on high-grain
rations (particularly rations containing corn by-products) may be
deficient in thiamin (a B vitamin).
Ensure goats have access to clean,
fresh water and forage at all times. Goat Power Mineral should be
offered free-choice at all times. Goat Power products contain
copper. Do not feed to sheep or other copper sensitive species.
Angora and Pygmy goats have been reported to be sensitive to
copper supplementation.
