An experiment was conducted by feeding diets with different levels of lysine (1.20, 1.30 and 1.40% in pre-starter diet, 1.10, 1.20 and 1.30% in starter diet and 0.95, 1.05 and 1.15% in finisher diet) and methionine (0.45, 0.55 and 0.65% in pre-starter diet, 0.40, 0.50 and 0.60% in starter diet and 0.35, 0.45 and 0.55% in finisher diet) to commercial broilers for a period of five weeks to assess the muscle protein content in environmentally controlled and open sided housing system. The interaction between feeding different levels of lysine and methionine and housing system revealed no significant influence on breast and thigh muscle protein level in broilers.
