Abstract
The present experiment to investigate the effect of varying protein (Crude protein) and energy levels in diets of caged laying hens was conducted at Animal Nutrition Department and Central Poultry Research Station, Gujarat Agricultural University, Anand Campus, Anand from July 1981 to July 1982. For caged layer experiment, 3 power 2 factorial experiment was used with three levels of protein (16, 18 and 20 per cent) each with three levels of energy (2700, 2600 and 2500 Kcal ME/kg). The treatments (Proteins per cent: Kcal ME/kg) were T1- 16:2700, T2 - 18:2700 (as per ISI specifications), T3 - 20:2700, T4 - 16:2600, T5 - 18:2600, T6 - 20:2600, T7 - 16:2500, T8 - 18:2500 and T9 - 20:2500. Twenty seven hens under each treatment maintained in California cages were individually fed one of the nine diets from 22nd to 72 weeks of age.
