Abstract

This study was conducted to assess the effects of dietary Lysine (Lys) and Methionine (Met) on the performance of broiler chicks. Ninety-six Hybro strain broilers were allotted to four groups, each included four replicates (6 birds per replicate) in a completely randomized design. The treatment groups received the same basal diet supplemented with Lys and Met in 00: 0.0; 0.10: 0.20 and 0.0; 0.7: 0.60; and 0.5 respectively. Data were analyzed using SPSS software; Duncan’s test was used to compare the means on a value of P< 0.05. Whereas feed conversion ratio (FCR) was the least in these two treatment groups (P< 0.05) showed that birds positively responded to dietary levels Lys and Met 0.1:0.6 tend to a significant increase in body weight gain (P<0.05). Results showed that increasing Lys and Met to diets of today’s broiler can improve immune system functions, FCR, carcass efficiency. This reveals the possibility to produce healthier and economic poultry meat by supplementation Lys and Met to broiler diets increased gross marginal profit.
