Economically Balancing the Equine Diet

The cost of feeding horses can be brought under control by
identifying and analyzing your forages (hay and pasture) and
feeding only what nutrients are needed to make up the
difference between what is in your forage and what your
horse needs.
With
today’s cost of protein grains and cereal grains used in
formulating and manufacturing Diet Balancers and Grain
Mixtures for horses, owners can no longer afford to guess
what analysis needs to be in the horse feed they buy.
If your feeding program does not meet all your
horses’ nutrient needs, their health, growth, reproduction
and performance will be compromised to the extent of the
deficiency. If over fed, other health problems can occur,
and you may spend more money than necessary on feed and/or
supplements.
The following chart is a management tool for you
to use and compare the analysis of your forage, on a dry
matter basis. If the nutrient levels on your analysis
print-out are in-between the following “ranges”, under each
type of forage, then proceed by feeding the required
Progressive Nutrition (PN) “Units” per day found on the
PN Daily Feed Planner or PN Growth Monitoring Chart.
If the nutrients are higher or lower, call your local
Progressive Nutrition Dealer or your local PN Equine
Nutrition Consultant for special feeding directions.

*Relative Feed Value (RFV)
is a quality-grading standard assigned by the Hay Market
Task Force of the American Forage and Grassland Council
to help us determine the true value of forages.
Forages with values between 103 and 150
are good to prime quality, while forages between 103 and 75
are graded as fair to poor quality. This is based on the
availability of the nutrients with-in the plant.
If
your forage RFV were above 150 or under 103, the nutrient
analysis would change accordingly and so would the level of
nutrients you will need to add/day. The nutrient levels
with-in the plant are affected most by: 1) type of forage
and 2) maturity at harvest. The following will also affect
these levels, but to a lesser extent: 3) soil type where
they are grown, 4) amount of fertilizer applied, 5) amount
of rainfall and 6) ambient temperature while growing.
A Progressive Nutrition
(PN) “Unit” is made up of
protein (amino acids), fats (fatty acids), major minerals,
trace minerals and vitamins necessary to complement the
analysis of your forages (grass or legume. Our Diet
Balancers are concentrated sources of these nutrients, which
means one PN “Unit” is equal to one pound of the appropriate
Diet Balancer. How many PN “Units” to feed per day will
depend on your horses: size, current growth rate,
reproductive status and/or performance level. See our
recommendations on the
PN Daily Feed Planner (Equine
Management Guide #104) and/or PN Growth Monitoring Chart
(Equine Management Guide # 106). Which Diet Balancer to
feed will depend on the type of forage your horses are
eating.
These
are the Nutrients that make up One PN “Unit”, which is found
in each pound of our ProAdvantage Diet Balancers that
Complement Each Forage Type
