Abstract

A six week growth performance trial involving 450 birds was conducted to determine the dietary requirement of broiler chicks for available methionine (AM). Body weight gain was significantly (p<0.01) lower on high AM diet (1411 g/bird) than low AM (1470 g/bird) and normal AM (1466 g/bird) diets. The feed intake by birds ranged from $3241{\pm}25.69$ in high AM diet to $3321{\pm}25.69g/bird$ in low AM diet. The feed efficiency for the three diets having low, normal and high level of AM were $2.26{\pm}0.02$, $2.24{\pm}0.02$ and $2.30{\pm}0.02$, respectively. The results indicated that the birds fed high AM diet consumed significantly (p<0.01) more feed per unit body weight gain as compared to birds on low and normal AM diets.
