Abstract

An experiment was conducted to study the effects of b-glucanase supplementation on the performance and GASTROINTESTINAL TRACT size of chicks fed BARLEY based diets and growth stimulator ANTIBIOTICes up to 42 days. In this study 400 day-old Ross male chicks were used (each pen had 25 chicks) in a completely randomized design with four treatments: 1- control (barley based diet), 2- control+ enzyme supplementation (500U avizyme), 3- contro1+ antiobiotic (virginiamycin, 20 ppm), 4- control+ enzyme supplementation (500U avizyme) plus antiobiotic (20 ppm) and four replicates. The traits measured were feed intake, feed conversion ratio, body weight gain, and gut development. Inclusion of enzyme significantly increased body weight (P< 0.05). There were no significant differences between treatments for feed intake. Feed conversion ratio was significantly impacted by adding of enzyme supplementation in treatments 2 and 4 (2.13 and 2.1 versus 2.27).ANTIBIOTIC supplementation had no significant effect on body weight, feed intake and GASTROINTESTINAL TRACT development. The addition of BARLEY in the diet decreased the performance due to presence of nonstarch polysaccharides and enzyme significantly decreased relative weight and length of juojenum and ileum (P<0.05), which shows adaptation process in BROILERs exposed to higher level of BARLEY.
