Whole soybeans: Why hasn't
pet food found this ingredient?
About soybeans

In the midst of a "whole
grains" trend in human
food, it might be worth
it to look at whole
soybeans as a possible
pet food ingredient.

S

oybeans are much maligned
and vilified in the pet aisle.
Claims of "No Corn, No Wheat,
No Soy" are common. Yet we have been
feeding soy as soybean mill feed or millrun,
soybean meal, soy protein concentrate or
isolate, and soy hulls for as long as commercial pet food has been around. These ingredients have served a valuable purpose with
few issues. What we have not been using in
pet foods are whole soybeans. Much like the
"whole grains" movement in human foods,
whole soybeans might be an interesting
ingredient to consider.

Globally, the U.S. is the
leading producer of soybeans
with Brazil and Argentina a
close second and third. In 2018,
U.S. farmers grew over 123
million metric tons (U.S. Department of Agriculture National
Agricultural Statistics Service,
February 2019). Whole soybeans
are rich in protein (35-40%)
and fat (22-25%) with relatively
modest levels of ash (5%) and
crude fiber (4%). The protein
is shy on methionine but has
plentiful lysine, and the fat is a
meaningful source of the essential linoleic acid. So it serves as a
great complement to the cereals.
On the other side of the ledger, soybeans
also are known to contain urease inhibitors, trypsin inhibitors, phytate phosphorus,
hemagglutinins and phytoestrogens among
the antinutritional compounds. This means
they have to be processed to remove these
from being a factor in the diet. And of
course, most soybeans produced in the U.S.
are genetically engineered these days.

foods
So how do they feed in dog and cat
