Comparative Study of the Effects of Probiotic and Commercial Enzyme on Growth Rate, Haematology and Serum Biochemistry of Broiler Chicken
Author(s): Ezema ChukaEzema Chuka
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).
