Abstract

A total of 240 Ross broiler chicks, 14 days old, were used. The chicks were randomly allocated to four treatments of three replicates per group each replicate consists 10 chicks. All chicks were reared in two rearing system, in floor and cage. Chicks in each rearing system were subdivided into four treatment groups as follow: T1: Chicks fed the control diet. T2: Chicks fed the control diet + 0.75% dried yeast. T3: Chicks fed the control diet + 1.5% dried yeast. T4: Chicks fed the control diet + 2.25% dried yeast. The result of this study were showed that the use saccharomyces cerevisiae (Sc) in diets were significant improved (p≤0.05) average body weight gain ,average fed consumption , feed efficiency , production index ,dressing percentage. Chicks fed diet supplemented with higher percentages of S.c. (T3 and T4) were significantly (p≤0.05) improved all productive performance characteristics as compared with T1 and T2 broiler performance in cages seemed to be better than floor system.
