Abstract |
This study conducted to
evaluate the effect of prebiotics (Fermacto), isoleucine and their
combination on carcass characteristics and morphology of ileum during
finisher period in broiler. A total 300 one-day-old mixed Ross broiler
chicks were reared in same condition up to 21 day. Birds were
distributed randomly into 4 treatments and 5 replicates. Control group
was fed with the basal diet composed of corn-soya and wheat.
In the experimental
groups; either 0.1% prebiotic and 0.04% isoleucine or their combination
was added. The experiment lasted from 22 to 42 days of broiler age. The
results at the end of the experiment showed that prebiotic and
isoleucine significantly (P<0.05) improved the efficiency of the villus
height, width and the ratio of villus height to crypt depth and
reduction of crypt depth, but it had no significant effect on traits
such as dressing percentage, breast weight, abdominal fat weight and
weight of bursa, however, the leg weight increased significantly in the
group fed isoleucine and prebiotic. These results showed that the
combination of prebiotic and isoleucine improved the leg weight and
intestinal morphology in broiler.
