Effects of supplementing different levels of meat and bone meal on productive performance, carcass characteristics and hematobiochemical parameters in broiler

Meat and bone meal (MBM) is a potential source of dietary protein for broiler. One hundred Cobb 500™ unsexed day old broiler chicks were used in a 28-day trial to investigate the effects of different levels MBM on productive performance, carcass characteristics and blood parameters in commercial broiler. Birds were randomly distributed into five dietary treatment groups designated as T0, Tp T2, T3 and T4 and supplemented with 0, 2, 4, 6 and 8% MBM for T0, Tp T2, T3 and T4 treatment groups, respectively. All birds had free access to feed and water. Results indicated that, weekly average weight gain increased significantly (P 0.05) at 2nd and 3rd weeks but differed (P 0.05) on blood parameters. Total protein differed (P<0.01) at 4th week. It was concluded that, increasing levels of supplemental MBM substantially improved performance parameter and carcass characteristics without interfering hematobiochemical parameters in broilers.
