- Abstract
The study was conducted to determine the effect of different enzymes on the performance of broiler chicks. For this purpose, one hundred and twenty day-old broiler chicks were purchased from a local hatchery and were randomly divided into 12 experimental units of ten chicks each. These experimental units were further divided into 4 groups in such a way that each group has 3 replicates. Each experimental unit (replicate) of the chicks was randomly placed in a separate pen. Group (A) served as control and was fed only commercial broiler ration without any enzyme. While Group B, C and D were fed commercial broiler ration plus Econase, Avizyme and Zympex enzymes @ 5, 10 and 25 g/bag of feed, respectively (as recommended by manufacturers). The results revealed significant effect of enzymes supplementation on weight gain, feed consumption and feed conversion ratio. The data revealed that the over all performance of broilers improved significantly with enzyme supplementation. The broiler fed different enzymes significantly gained 10-13.9% more weight; consumed 5.9-9.9 % more feed and improved 3.5-7.5% feed conversion ratio as compared to control. It is concluded from this study that enzymes supplementation significantly improved dressing percentage, while it did not reveal any significant effect on relative weights of liver, gizzard, heart and spleen. Net profit per bird also improved in enzymes groups as compared to control.
