Influence of Different Levels of Energy and Protein on Body Weight and Body Weight Gain of Broilers in Environmentally Controlled Housing System.

An experiment was conducted by feeding diets 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) to commercial broilers for a period of five weeks to assess the production performance. The result of the experiment revealed that high energy and high protein group viz. CP 23.5, 22.5 and 21.0 and ME 3050, 3150 and 3250 kcal/kg in the pre-starter, starter and finisher diets respectively had significantly (P<0.05) higher body weight and body weight gain than rest of the experimental groups.
