RESPONSE OF DIFFERENT GENOTYPES OF BROILERS TO LYSINE SUPPLEMENTATION RAISED UNDER PRACTICAL CONDITION
Abstract: This study evaluated
lysine supplementation of 4 to 42 day of age of two commercial broilergenotypes
(Arbor Acres and Lohmann). Four hundred and fifty day-old chicks were sexed
andrandomly distributed into 60 bamboo pens each 2 m2. A starter commercial
diet as a basal diet wassupplemented 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 22-42days of age. Feed
consumption, body weight gain and FCR were determined on weekly basis. On d
43of experiment, 4 birds per each replicate were processed for carcass
parameters. Results of the studyrevealed 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. ArborAcres broilers response more efficient in low lysine
whilst Lohmann broilers were better in a higherlevel of lysine.
