Influence of Different Levels of Energy and Protein on Production Performance of Male Broilers Reared Under Environmentally Controlled Housing System.

An experiment was conducted by feeding diets with three level 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 three levels of 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) to commercial male broiler chicken for a period of five weeks to assess the production performance in environmentally controlled housing system. The results of the experiment revealed that different level of energy and protein in the diet had significant influence (P<0.05) on body weight, body weight gain, feed intake and feed conversion ratioof male broilers where high energy high protein group showed better body weight and feed conversion ratio compared to rest of the tre a tment group.
