One hundred forty-four medium-framed
crossbred steers averaging 857 lb were used to
evaluate steer performance and determine net
energy (NE) values of finishing diets that
included dried bakery product (DBP). DBP replaced
corn in the control diet at 15 or 30% of
dietary DM. DM intake was depressed 6.5%
by inclusion of 30% DBP. No differences in
daily gain (P>.3) or feed efficiency (P>.9)
were observed by replacing corn with DBP.
Dietary values of NEm and NEg, calculated
from animal performance, were not affected
(P>.7) by the inclusion of DBP. Kidney,
pelvic, and heart fat (KPH) (P<.05) and 12th
rib fat thickness (P<.1) were increased
linearly with inclusion of DBP, whereas other
carcass characteristics were unaffected. These
data indicate the DBP (10% rice hulls included)
has an energy value similar to that of corn
grain, although the optimal inclusion level of
DBP appears to be below 30% of dietary DM.
