摘要

The study investigated the combined and individual effects of probiotic (Saccharomyces cerevisiae) and a commercial enzyme (Zyme?) on weight gain, haematology 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 (0.02 ml/lit) but no probiotic. P3 had enzymes in their water (0.02 ml/lit) and probiotic in their feed (0.8 g/kg). P4 had probiotic in their feed (0.8 g/kg) but no enzymes in their water. The results showed that birds in group P4 had significantly (P ≤ 0.05) higher final mean weight (2.51 ± 0.05 kg/bird) followed by P3 (2.43 ± 0.05 kg/ bird) while P1 (the control) had the least final mean weight (2.31 ± 0.02 kg/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), supplementation in the feed with probiotic alone is recommended for improved broiler production in this environment using this type of diet.
