ABSTRACT

The experiment was conducted to study the effect of different levels of symbiotic on the performance, carcass characteristics, serum attributes and economical appraisal of broiler chicks. A total of one hundred and five, seven days old, unsexed Arbor Acers strain were used. Chicks were divided into five experimental (A,B,C,D and E) dietary diets, each treatment was further subdivided into five replicates in a complete randomized design. The first group (A) fed on control diet (negative control), group (B) fed on control diet supplemented with (0.5mg /kg) klavamycin as positive control, group C,D and E were fed on control diet supplemented with 0.5mg/kg, 1mg/kg, 2mg/kg symbiotic respectively. Experimental diets were fed for five weeks. Results obtained showed that supplemented of broiler diets with symbiotic recorded significantly (P0.05) effect in FCR compared to both NC and PC.

Result also showed no significant difference for non carcass components, commercial cuts and their meat/bone ratio. Result obtained for meat chemical attributes revealed significant (P
