ABSTRACT
An experiment was carried out to evaluate the replacement value of local maize offal (dusa) in broiler
starter and in finisher diets. The levels of inclusion of dusa were 0, 10, 20, 30, 40, 50, 52.43 and 0, 10,
20,30,40,50,63.98% for starter and finisher diets respectively.
The results showed that from 0-4 weeks of age, there was no significant differences (P>0.05) in weight
gain, feed consumption, feed conversion efficiency and mortality rate between the control, and other
treatments. Feed cost per unit gain was significantly (P<0.05) reduced for other treatments when
compared with the control diet.
From 5-8 weeks when finisher diets were fed, results showed that there was no significant difference
(P>0.05) in weight gain, feed consumption, feed conversion effeciency and mortality rate between all
the treatments and the control. However, feed cost per unit gain was significantly (P<0.05) reduced
for other treatments compared to the control diet with 52.43% dusa diet having the lowest unit cost
per gain, Similary, the pooled results for 0-8 weeks showed that there was no significant difference
(P>05) in weight gain, feed consumption, feed conversion efficiency and mortality rate between other
treatments and the control.
It can be concluded that local maize offal (dusa) can completely replace maize in broiler starter and
finisher diets without any adverse effect on weight gain, feed consumption, feed conversion efficiency,
mortality rate and carcass parameters.
