Abstract

An experiment was conducted to evaluate the performance of broiler by supplementation of Phytase with or without using feed matrix. 375 day old Vencobb400 straight run chicks were weighed and distributed randomly into five treatment groups viz, A, B, C, D and E with three replicates of 25 chicks each. The recommended nutritional matrix for 500 FTU and 1000 FTU was used as per manufacturer guidelines. Treatment group A was basal diet without phytase enzyme. The body weights, weight gain, feed consumption and FCR up to 6th week of age were non-significant. The performance of Phytase supplemented groups was at par to that of control even by reducing the nutrients as per matrix and best performance was observed for Treatment groups E . The serum calcium values at 42 days did not differ significantly, however serum phosphorus values showed significant (P
