Abstract:
An experiment was conducted by using two hundred commercial (Vencobb), sexed, day-old chicks for a period of six weeks to study the dietary supplementation of valine with respect to production performance of broilers. These chicks were randomly grouped into five treatments with four replicates of ten chicks each and fed with basal diet as T₁ (Control), T₂ (Basal diet + 0.04 per cent valine), T₃ (Basal diet + 0.08 per cent valine), T₄ (Basal diet + 0.12 per cent valine) and T₅ (Basal diet + 0.16 per cent valine). The experimental feed was formulated according to the Vencobb standards by supplementing graded levels of valine for different treatment groups. The supplementation of valine in broiler diets up to 0.16 per cent did not show significant improvement in sixth week body weight. The supplementation of valine in the diet of broilers had significant differences in (P<0.01) feed consumption per bird per day, cumulative feed consumption (P<0.05) and feed conversion ratio (P<0.01) of broilers at sixth weeks of age. The dietary treatments had no significant effect on livability. Based upon this study, it is concluded that supplementation of valine in basal diet at the level of 0.04 per cent (T₂ group) did not affect the production performance of broilers.
