Two biological trials were conducted to determine the energy and lysine requirementsof “TANUVAS Namakkal gold Japanese quail” for production performance. The economic impact of different levels energy and lysine during the chick (0-2 weeks) and grower (3-5weeks) phases was assessed using seven hundred and twenty straight-run, day-old chicks randomly grouped in nine treatments with four replicates of twenty chicks each. Three levels of energy (2800, 2900 and 3000 kcal/kg) and three levels of lysine (1.2, 1.3 and 1.4%) were tested for chick and grower phase of the first experiment. The net profit per bird (Rs. 8.49) was high in group T1 (low energy and low lysine) and the net profit per kg live weight (Rs. 48.57) was high in T2 (2900 kcal/kg and 1.2%). For the second experiment an energy level of 2700, 2800 and 2900 kcal/kg was fixed for chick and grower mash, lysine level of 1.2, 1.3 and 1.4% was fixed for chick phase and 1.1, 1.2 and 1.3% for grower phase and the crude protein level wasfixed as 20.3 and 19.4 per cent for chick and grower mash respectively for the second trial. The net profit per bird (Rs. 7.18) was high in group T6 and the net profit per kg live weight (Rs. 37.62) was high in T6 (2900 kcal/kg and 1.3% lysine during chick phase and 1.2% lysine during the grower phase).
