Abstract

The objective of this study was to evaluate the nutritive value and to determine the optimal inclusion level of extruded soybeans on broiler perfomance.Two hundred day old male broiler Loghman chickens obtained from commercial hatchery were randomly distributed into 40 groups. Two experimental diets i.e. raw soybeans (M) or soybeans extruded (E) were arranged as a 2 x 5 nested combination of level inclusion on diets. Extruded soybeans or raw soybeans were then incorporated at 0%, 5%, 10%, 15%, and 20% inclusion in broiler diets. During starter phase, broiler were fed diets containing 3200 kcal/kg ME, 23% crude protein for the finisher phase broiler were fed diets containing 3200 kcal/kg ME, 20% crude protein. Result of this experiment showed that extrusion processing decrease trypsin inhibitor activity and urease activity. Treatment extruded soybeans showed difference (P<0.05) on feed consumption, body weight gain, feed:gain ratio, mortality and income over feed cost. There was no difference in carcass wieght, edible meat weight, abdominal fat weight, liver weight and pancreas weight (P>0.05). There were significant effect level inclusion nested on treatment (P<0.05) on feed consumption, body weight gain, feed:gain ratio, income over feed cost, edible meat weight, abdominal fat weight, liver weight and pancreas weight. But there were no significant effect level inclusion nested on treatment (P>0.05) on mortality and carcass weight. Extrusion processing conducted on soybean increase feed consumption, body weight gain, income over feed cost, but reduce feed:gain ratio, mortality, abdominal fat weight, liver weight, and pancreas weight. There no differences between level inclusion of extruded soybeans on body weight gain, feed:gain ratio, mortality, income over feed cost, edible meat weight, abdominal fat weight, liver weight, and pancreas weight. It was concluded that using extrusion soybeans on broiler diet showed satisfactory on broiler performance. It’s suggested to used up to 20% extruded soybeans in broiler diet (JIIPB 2009 Vol 19 No 2: 100-112).
