How do the nutritional values
of wheat compare to corn?
The increase in corn prices raises
the interest for wheat in animal feeds.
IOANNIS MAVROMICHALIS

T

he late planting of corn in the U.S. Corn Belt
this spring is expected to bring about a much
smaller crop at harvest time. This means less
corn will be available for feeding animals, and what
will be marketed will be quite expensive.
When corn prices spike, alternatives such as wheat
and sorghum are sought. And, although the U.S. has
considerable experience feeding sorghum, there are
fewer such experiences in the case of wheat. The opposite is true in Canada, and of course Europe, where
wheat remains the major cereal for most animal feeds.
Thus, transferring some wheat-feeding knowledge
across the pond is deemed expedient as we approach
corn harvest time in the U.S.
The most important aspect of wheat that we need
to keep in mind is that nutrient variability between
varieties is often greater than what is to be expected
between wheat (as a mean value) and other cereals. For
example, protein in corn varies between 6% and 10%
(extreme values), with common feed varieties giving a
more stable value of 8% protein. In contrast, protein in
wheat varies from below 10% (in some soft varieties)
to more than 18% (in some hard varieties) with no

accepted mean value for all wheat. Thus, before we
even want to begin discussing wheat, we must identify
the variety, and if not, run a basic (proximate) analysis
to be able to formulate diets correctly. In fact, this lack
of information is why so often new or occasional users
of wheat find it a disappointing exercise.
So, let us examine its nutritive value in more detail.

Energy
It is often said that the energy value of wheat is about
95% of that in corn. Again, this is a generalization as
wheat varieties rich in non-starch polysaccharides,
which are not utilized at all, can have a much lower
energy value. In addition, when protein levels in wheat
spike, then starch (energy) is lower, because something
must give in to make space for something else. Luckily,
there are prediction equations for energy value in wheat,
and using them greatly helps bring precision in formulation and predictability in animal performance.

Protein
Protein is a major key nutrient with great variability
in wheat. Often, knowing the variety is good enough
