Effect of Varying Levels of Probiotic on the Performance of Broiler Chicks

Abstract

The experiment was conducted to investigate the effect of varying levels of probiotic (Toyocerin®) on the performance of broiler chicks in a completely randomized design. One hundred and fifty broiler chicks were divided into five experimental groups (three replicates of ten chicks each). Broiler chicks were raised for 42 days. Five isocaloric and isonitrogenous broiler starter and finisher diets were formulated. Toyocerin® was added at the level of 0, 25, 50, 75 and 100 g/100 Kg of diet and denoted as T1, T2, T3, T4 and T5 respectively. Whereas, T1 was treated as a control group. Weekly body weight gain, feed consumption and feed conversion ratio were recorded. At the end of trial, two birds per replicate were slaughtered randomly for the determination of carcass traits. The addition of Toyocerin® in the diet of broilers (8-42 day) significantly improved the body weight gain, feed intake, feed conversion ratio, dressing percentage, breast meat yield and liver weight as compared to control group. The findings revealed that addition of Toyocerin® improved birds’ performance and carcass traits
