in this study the effect of starter chick weight at hatch and the level of dietary methionine supplementation of diets were evaluated. a total of 1,984 males chicks (agross) with two initial weights (40 and 45 g) were used. these birds were fed a pre starter diets supplemented with different levels of methionine (0,455 %; 0,507 %; 0,559 % e 0,611 %). all the diets had the same amount of metabolizable energy and crude protein. the birds were randomly distributed in a factorial design (two body weights and four levels of methionine). four replicate and 62 birds per replicate were used. these results showed that the interaction between initial weight and methionine levels was not statistically significant. The methionine levels did not affect the performance and the carcass yield of the birds at 47 days. chicks with the initial different weight were similar at 47 days and the supplementation of the methionine in pre starter diets did not affect the performance of the birds.KEY-WORDS: carcass yield, feed intake, feed-to-gain ratio, wieght gain.
