Whole grains in broiler diets
may boost feed efficiency
Including whole grains in chicken diets boosts growth and may
cut feed costs.
MARK CLEMENTS

Studies on including
whole grains in
broiler diets, carried
out by Amy Moss
at the University of
Sydney, have found
that feed conversion
rate increases while
feed costs go down.

Including whole grains in broiler diets can
increase the efficiency of meat production and
offer feed cost savings, work at the University of
Sydney, Australia, has shown.
Research by Amy Moss, PhD student at the
university's Poultry Research Foundation, has
found that replacing some of the ground grains
in chickens' feed with whole grains not only
improves digestion, but also influences how

efficiently birds convert feed into meat.
Moss' studies have found that whole grain
feeding naturally enhance birds' innate capacity
to digest. While pellets may be appetizing
to chickens, they break up very easily once
ingested, and this provides very little stimulation
for the gizzard. This lack of stimulation leads
to less gastric stimulation and poorer digestion,
ultimately reducing the amount of meat produced
per kilo of feed consumed.
But a stimulated, more muscular gizzard
not only grinds down the whole grains; it
also stimulates the production of more gastric
solutions, so making better use of the feed.
The study has found that, by replacing about
30 percent of ground grain with whole grains,
chickens produced 7.7 percent more meat per kilo
of feed eaten. Additionally, the cost of feed is
lowered.
Whole wheat can be added to poultry diets in
two ways: after pelleting as a separate entity to
the pellet (post-pellet whole grain feeding), or it
can be incorporated during pelleting (pre-pellet
whole grain feeding), and each method would
appear to have its own benefits and drawbacks.
