Material type: materialTypeLabelBookPublisher: 1999Subject(s): Department of Animal NutritionDDC classification: 0610,T Dissertation note: 1 lie present study was under taken to investigate the effects of different levels of soybean meal as an only protein source on the performance of the growth rate, feed intake, feed efficiency , dressing percentage, mortality and economics of the broiler chicks. One hundred and sixty day old Hubbard chicks were purchased from the local market and were reared on four isocaloric and isonitrogenous rations 1, 2, 3 and 4 up to 28 days of age containing 32.2, 27, 23 and 1 7% Soybean meal. Weekly feed intake, body weight gain and mortality was recorded. At the end of experiment three birds from each replicate were slaughtered to determine the dressing percentage. The data collected was applied by applying analysis of variance technique using least significant difference (L.S.D.) test to detect the difference among the treatment and means, were compared. Results revealed a highly significant difference among weight gain and rat ion I having the maximum level of soybean meal showed best weight gain, and then in a declining order, with the decrease in soybean meal level in the diets, the weight gain of oilier groups decreased. Non significant difference was noticed in the fed consumption of different experimental rations led to the chicks. Apparently better feed conversion ratio was noticed by the chicks fed on ration (32.2% Soybean meal), hen COfl1CS ration 2 (27% soybean meal). then ration 3 and 4 (23% and 17% soybean meal) respectively. The present results revealed that chicks fed on ration 1 (32.2% soybean meal) apparently showed increased growth of broiler chicks, required less amount of feed per unit weight gain and were economical as compared to birds fed on other experimental rations.

1 lie present study was under taken to investigate the effects of different levels of soybean meal as an only protein source on the performance of the growth rate, feed intake, feed efficiency , dressing percentage, mortality and economics of the broiler chicks. One hundred and sixty day old Hubbard chicks were purchased from the local market and were reared on four isocaloric and isonitrogenous rations 1, 2, 3 and 4 up to 28 days of age containing 32.2, 27, 23 and 1 7% Soybean meal.

Weekly feed intake, body weight gain and mortality was recorded. At the end of experiment three birds from each replicate were slaughtered to determine the dressing percentage. The data collected was applied by applying analysis of variance technique using least significant difference (L.S.D.) test to detect the difference among the treatment and means, were compared.

Results revealed a highly significant difference among weight gain and rat ion I having the maximum level of soybean meal showed best weight gain, and then in a declining order, with the decrease in soybean meal level in the diets, the weight gain of oilier groups decreased.

Non significant difference was noticed in the fed consumption of different experimental rations led to the chicks.

Apparently better feed conversion ratio was noticed by the chicks fed on ration (32.2% Soybean meal), hen COfl1CS ration 2 (27% soybean meal). then ration 3 and 4 (23% and 17% soybean meal) respectively.

The present results revealed that chicks fed on ration 1 (32.2% soybean meal) apparently showed increased growth of broiler chicks, required less amount of feed per unit weight gain and were economical as compared to birds fed on other experimental rations.
