Abstract

The experimental was conduct to study the growth promoter Vigest with comparison of antibiotic Neomycin effect on performance values of broiler The experimental design was used in the experiment was complete randomize design (CRD).Total number of chicks 72 chicks at 7days old unsexed .Aberekier strain, divided into 3 experimental groups with 3replicates each of 8 chicks. The first group represent Vigest as growth promoter (A),the second group (B)fed on antibiotic neomycin and group (C)as control group fed on basal diet without feed additive. It was the same circumstances in terms of nutrition and care for duration of experimental and been recording and collecting information, Feed intake, Feed conversion ratio and body weight gain of chicks every week, daily growth and mortality rate. The results obtain from this experiential chick on group (A) was recorded highly body weight gain is significant different P<0.05 among all treatment groups and group (C) was remake a lower consumption on feed intake .Results of feed conversion ratio there no significant difference among all treatments.
