| Abstract | ||
| A Total of 180 day old male Cobb broiler chicks were raised, from day old untill 42 day of age to investigate the effect of adding graded levels of methionine (0.10, 0.15 and 0.20%) in comparison with basal diet on broiler body weight, uniformity and the relationship between economical traits and economical efficiency. The birds were equally distributed into four groups , with 45 birds each,and were allocated in three replications. Highest body weight was found in the chicks group that consumed ration consist in (0.15%)methionine at various ages.This treatment showed similar results for body weight uniformity and relative growth rate, in comparison with the other treatment groups. Feed conversion was significantly altered due to effect of methionine supplementation at (0.15 ,0.20%)levels vs first treatment. Feed intake and liveability were not affected by any level of methionine supplementation. Economical efficiency of the third group was the best when compared with others. Regression and simple correlation analyses revealed that third treatment showed that relationships among the performance traits was the best at 42 days of age. | ||
