Abstract :

The study investigated the combined and individual effects of probiotic ( Saccharomyces cerevisiae ) and a commercial enzyme (Zyme) on weight gain, hematology and serum biochemistry of broiler chicken. Eighty day-old broiler chicks were randomly divided into 4 groups (P1-P4) of 20 birds each. Each group was subdivided into 5 replicates of 4 birds each. P1 had no probiotic and no enzymes (control). P2 had enzymes in water (0.02ml/lit) but no probiotic. P3 had enzymes in their water (0.02ml/lit) and probiotic in their feed (0.8g/kg). P4 had probiotic in their feed (0.8g/kg) but no enzymes in their water. They were fed ad libitum. The quantity of feed consumed each day were determined. The birds were weighed weekly. At their 6th week hematology and serum biochemistry were determined following standard procedures. The result showed that birds in group P4 had significantly (P≤0.05) higher final mean weight (2.51�0.05kg/bird) followed by P3 (2.43�0.05kg/bird) while P1 (the control) had the least final mean weight (2.31�0.02kg/bird). There was a significant difference (P<0.05) in Eosinophil levels in P3 (probiotic and enzyme) and P4 (probiotic only). Serum cholesterol significantly (P≤0.05) decreased while total proteins were higher in probiotic treated groups (P3 and P4). P3 (probiotic + enzyme) gained less weight than P4 (Probiotic only) hence the combination of probiotic and enzyme was not recommended.
