Prebiotics are nutrients which are not digested, and
selectively improves growth and activity of beneficial microbes in large
intestine. The objectives of this research were to study the performance, the
percentage of carcass, abdominal fat, and giblets of broilers given a ration
contained prebiotic from corncobs. This research used factorial completely
randomized design which consisted of two factors. The first factor was
consisted of three treatments: basal ration, basal ration + 2.5% prebiotics,
and basal ration + 0.01% bambermycin, the second factor was consisted of two
treatments: without E. coli’s infection and with E. coli’s infection, with five
replications (10 birds/replicate). The variables observed were performances,
the percentage of carcass, abdominal fat, and giblets. The results show that
the performances and the percentage of carcass, abdominal fat, and giblets of
the broiler given a ration contained prebiotics did not significantly different
to the other treatments. It is concluded that prebiotics supplementation in the
broiler ration has no significant influences on performances and the percentage
of carcass, abdominal fat , and giblets of broilers. However, prebiotic were
able to replace the antibiotic to reduce mortality of broilers at five week of
age.
