| dc.description.abstract | The study was conducted to evaluate the effects of valine supplementation in standard broiler diet. The parameters were the following: production performance, carcass yield and income over feed cost. A total of 384 day-old Cobb broiler chicks were used in the feeding trial. The broiler were randomly assigned to different dietary treatments. Specifically, D1 - standard broiler diet (SBD), D2 - standard broiler diet + 0.01 valine, D3 - standard broiler diet + 0.02 valine, D4 - standard broiler diet + 0.03 valine. Each treatment used eight replications having twelve birds per replicate. Results from the study revealed that feeding with D3 and D4 provided higher average daily gain of birds all throughout the production. D2 attained the lowest average daily feed intake. D4 also achieved an ideal feed conversion ratio. However the results were insignificant. Low percent livability was observed in the D2 that was significantly different compared to the other treatments. In terms of carcass yield. D2, D3 and D4 all presented higher live weight and carcass weight. However, D2 and D4 showed better dressing percentage compared to the control. Income over feed with D3. There is no significant result in carcass yield and income over feed cost. Supplementation of commercially available valine was too low ( 0.01 % to 0.03% of the diet), it can be recommended for further studies to increase the conclusion rate of valine supplement in the diet. | |
