%X This study evaluated lysine supplementation of 4 to 42 day of age of two commercial broiler genotypes (Arbor Acres and Lohmann). Four hundred and fifty day-old chicks were sexed and randomly distributed into 60 bamboo pens each 2 m2. A starter commercial diet as a basal diet was supplemented with lysine mono-HCL in a 2x2x5 factorial arrangement with lysine levels of 0.0, 0.5, 1.0, 1.5 and 2.0 g/kg fed from 4-21 days of age, and then followed by a finisher diet fed from 22-42 days of age. Feed consumption, body weight gain and FCR were determined on weekly basis. On d 43 of experiment, 4 birds per each replicate were processed for carcass parameters. Results of the study revealed that lysine supplementation in a starter commercial diet increased significantly carcass weight (P<0.05. Improved breast meat and lower abdominal fat were found in lysine supplementation. Arbor Acres broilers response more efficient in low lysine whilst Lohmann broilers were better in a higher level of lysine.
