Protein and energy levels in poultry starting diets growth response in winter and spring reared chicks

, : Protein and energy levels in poultry starting diets growth response in winter and spring reared chicks. Indian Journal of Animal Sciences 45(4): (1977) 224-233

Two experiments were conducted, i.e., experiment 1 in winter and experiment 2 in spring, each with 216 day old female Hyline chicks; 12 rations were fed in 3 .times. 4 factorial arrangement with 2 replicates, 3 levels of protein (18, 20 and 22%) and 4 levels of energy (2340 .+-. 19.18, 2550 + 31.08, 2860 + 32.85 and 3150 .+-. 16.09 kcal ME/kg). The rearability of chicks was high on all rations in both the experiments. The mean weight gained by chicks to 8 wk of age varied between 515 g for 18-3150 (protein % and ME kcal/kg, respectively) ration and 693 g for 22-2550 ration in winter, and between 419 g for 18-3150 ration and 536 g for 20-2340 ration in spring. Differences between rations were highly significant for protein effect for the 2 experiments and for energy effect for experiment 1 only. Winter-reared chicks showed higher body weight gain and feed intake. Most efficient feed conversion was obtained for 22-2550 ration in winter-reared chicks and 22-3150 ration in spring-reared chicks. Efficiency of utilization of energy varied inversely with the energy content of ration. Although protein utilization was satisfactory at all protein levels tested, 18% protein rations appeared unsatisfactory for growth.
