Abstract
A total of 320 day old Cobb broilers were used to determine the effect of valine supplementation at various level in diet with reduced amount of lysine on growth performance, carcass yield and income over feed cost. The birds were randomly allocated to four dietary treatments namely; 75% val:lys, 84% val:lys, 87% val:lys, and 92% valy:lys. Each treatment had 8 replications per treatments and 12 birds per replicate. Results showed significant differences in gain in weight, feed intake, and feed conversion ratio. However, 75% val:lys had the highest value among the four treatments. Carcass yield and cut-up parts showed no significant differences, except breast meat yield which differed significantly. Income over feed cost also showed significant differences and 75% val:lys had the highest value.
