Performance of broiler chicken as affected by varying levels of multi enzyme supplementation.

A study was carried out to observe the effects of dietary supplementation of enzymes on the commercial broiler chicken. Day old chicks (n=240) were randomly distributed in 12 groups with three replicates. Four dietary treatments with varying levels of Allzyme-SSF® supplementation viz. C (Control, basal diet only), T1 (enzymes 0.015%), T2 (enzymes 0.020%) and T3 (enzymes 0.025%) were formulated and fed triplicate group of birds. The basal diet was formulated for starter (0–4 weeks) and finisher phase (4–6 weeks) separately following BIS (1992) requirements. Body weight gain (g) of the birds was significantly higher in treatment groups than control (981.89±6.34) at 0–4 weeks period and feed intake (g) in T1 (478.50±7.21) and T2 (473.67±2.52) than T3 (456.00±2.17) at 0–2 weeks of age. Feed efficiency was 2.05±0.01, 1.92.0±0.01, 1.93±0.01, 1.93±0.01 for control, T1, T2 and T3, respectively. Protein efficiency was significantly higher in enzyme treated groups as compared to control. Blood samples collected from 10 birds from each replicate during slaughtering at 42 days revealed no influence of enzymes on haemato-biochemical parameters. It is concluded that the supplementation of enzymes at varying levels to the diets of broiler chicken yielded positive effects on the birds performances with cost effective production and had no significant effect on haematobiochemical parameters of commercial broiler chicken of mixed strain.
