Abstract:
A study was conducted in commercial broiler chicks (Vencobb) for a period of six weeks to analysis the dietary supplementation of valine with respect to Body weight and Cumulative feed consumption at sixth week, Total feed cost per bird (Rs), Total cost of production per kg live weight (Rs), Total income per bird (Rs), Net profit per kg live weight (Rs), Net profit per bird (Rs). These broiler chicks were wing banded, weighed and randomly allotted into five treatment groups 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 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 cumulative feed consumption (P<0.05) at sixth weeks of age. The T₂ group (basal diet + 0.04 per cent valine) recorded the lowest Production cost per kg live weight (Rs 57.31) and highest Total income per bird (Rs 174.68), Net profit per kg live weight (Rs 16.69) and Net profit per bird (Rs 39.39). Based upon this study, it is concluded that supplementation of valine in broiler basal diet at the level of 0.04 per cent (T₂ group) increased sixth week body weight, Total income per bird, Net profit per kg live weight and Net profit per bird in a cost effective way.
