Abstract

Commercial broilers were fed with different levels of energy (2850, 2950 and 3050 kcal/kg in pre-starter diet, 2950, 3050 and 3150 kcal/kg in starter diet and 3050, 3150 and 3250 kcal/kg in finisher diet) and protein (21.5, 22.5 and 23.5% in pre-starter diet, 20.5, 21.5 and 22.5% in starter diet and 19, 20 and 21% in finisher diet) for a period of five weeks to assess the production performance in both environmentally controlled and open curtained housing systems. All the chicks were reared up to five weeks under standard managemental condition. During this experimental period, data on body weight, feed consumption and mortality if any were recorded at weekly interval. The result of the study revealed lower feed intake in group T₇ (2640.16 g) in environmentally controlled housing system and group T6 (2667.19 g) in open curtained housing system. The broilers reared in environmentally controlled housing system had significantly better feed conversion ratio (1.31 to 1.42) than broilers reared in open curtained housing system (1.45 to 1.52).
