Effects of Different Energy Protein Ratio on the Performance of Desi Native Chickens During Growing Phase

Mohammad Shehbaz Anjum and Sohail Hassan Khan    

Abstract: An experiment was conducted to determine the effect of different energy protein ratio on the performance of desi chickens during growing phase (9-20 weeks), Six different experimental rations having 2700 and 2900 kcal kg-1 of Metabolizable Energy (ME) and with 14 and 16% Crude Protein (CP), for female birds and 2750 kcal kg-1 ME with 14 and 16% CP for male birds. Each experimental group of each the male and female chicks had 12 replications having 20 chicks each. At the end of experiment, non-significant difference (p>0.05) was noted among weight gain, feed intake and Feed Conversion Ratio (FCR) in both male and female chicks. The feed cost per kg weight gain for female chicks fed diet having 14% CP and 2700 kcal kg-1 ME was lowered (p<0.01) than those of other groups. However, non-significant difference was observed in the cost of feed per kg weight gain for male chicks fed experimental diets. The minimum cost per bird in female chicks was noticed in birds fed diet having 16% CP and 2700 kcal kg-1 ME. Based on the findings of the present study, it may be stated that higher energy and protein levels in the feed may not be significantly improved the growth performance of the desi chicks in growing phase. However, the lower levels of energy and protein in the desi chicks diet may be significantly lower the cost of desi chicks rearing during growing phase.
