Fats Where
It's At
by Kelly PayneWhether
you're a health conscious individual, or watching
your weight, fat is something you want to avoid
in your diet. The media warns us that excessive
fat intake has been linked with everything from
heart disease to cancer. Therefore, the trend in
human nutrition is a low fat lifestyle.
Ironically enough, fat is
where it's at, in equine nutrition. What
may be bad for you, turns out to be a great
alternative energy source for the horse. Fat is
very energy dense and supplies 2.5 times more
digestible energy than an equal weight of cereal
grains (corn, oats, barley). Even though horses
do not have gall bladders, they digest fat very
well.
In most feeding situations,
horseman try to increase calories (energy) to the
horse by feeding more grain (carbohydrates) or
protein. However, increasing the grain portion of
the diet has its physiological limitations.
Exceeding the intestinal tract's capacity to
digest grain, leads to colic, laminitis or
founder, diarrhea, and exertional myopathy
(tying-up syndrome). For these reasons, it is
recommended that a grain or concentrate, not make
up more than fifty percent of the total diet.
Although increasing protein is
not as dangerous as exceeding carbohydrates,
protein is not an efficient energy source.
Proteins consist of amino acids, which are used
as structural building blocks for tissues,
organs, muscles, and bones. Only when there is an
inadequate intake of the other two sources of
energy, carbohydrates and fats, is protein used
for energy.
There are distinct benefits to
adding fat in the diet, thereby increasing the
diet's energy density or calories. The added
calories allow you to feed less grain in order to
meet the energy demands for athletic performance,
milk production, reproductive efficiency, growth,
or to maintain or increase body condition. Fat or
oils may be added to commercially prepared horse
feeds or supplemented to the horse's diet.
There are a number of different
sources of fat or oil on the market today.
Although different fats and oil vary in their
degree of saturation, they are all readily
utilized by the horse to provide the same amount
of energy. However, animal fats tend to not be as
pure as vegetable oils, which is the reason for
their slightly lower energy density. Also, animal
fat is not as palatable to horses, which is why
both the Legends line and Triple Crown line of
horse feeds only use vegetable oils.
Another alternative fat source
is rice bran. Rice bran is a highly digestible
vegetable fat, which is stabilized through an
extrusion process. This extrusion stabilizes the
fat, increases digestibility, and reduces the
potential for rancidity common in some other fat
sources. Triple Crown provides Rice Bran in a 50
pound bag which can be used to top-dress or
supplement fat to the diet, as well as
incorporating rice bran as a portion of the fat
in the Triple Crown Performance Formulas.
Another new product to the
market is called Triple Crown Conditioning Chaff.
Conditioning Chaff is a high quality oat hay with
added vegetable oil, to raise the fat guarantee
to 10%. This product is ideal for Endurance
horses and for horses with a history of colic or
laminitis (Founder) because it provides
significant calories, however it is low in
carbohydrates.
Generally, fats and oils cost
more per unit of weight than cereal grains, but
since they provide 2.5 to 3 times more energy or
calories, it may be more cost effective to feed a
higher fat diet. Remind customers to figure out
their cost per day, not their cost per bag, since
higher fat feeds provide more calories, less feed
is needed to provide the same amount of calories.
Most common horse feeds on the market today are
only 2-3% fat. Agway's lines of horse feeds
provide elevated fat levels. The Legends lines of
horse feeds now provide 6% fat, while the
Equitech textured feed provides 10% fat.
Likewise, Triple Crown's lines of Performance
feeds provide 10% fat.
Although the results of feeding
additional fat is a fairly slow process which can
take at least six to eight weeks, it is a safe
way to provide additional calories. For horses
under intense work or horses that are generally
hard to keep weight on, high fat diets provide a
safe way of meeting their energy/calorie
requirements without exceeding their starch
(carbohydrate) limits. Remember, fat
supplementation can alleviate the detrimental
effects of excess grain, yet accomplish the
needed and beneficial increase in the diet's
energy density.
