| Abstract | ||||
| This study was conducted with broiler chickens to investigate the effects of feeding program (P 1-3), feed form (S 1-2) and their interactions on productive performance and economic efficiency. In total 180 one – day old broiler chicks of the Indian River strain were used in the experimental with 6 treatments, 30 chicks each in 3 replicates of 10 chicks. The study consisted of a completely randomized experimental design with a 3 × 2 factorial arrangement of treatments and three program diets (P 1-3), P1 (24, 23, 21, 20 and 19%) and P2 (23, 21, 20 and 19%) and P3 (21, 20 and 19%) crude protein respectively, with two feed forms (S 1-2), S1 (crumbles/pellets) and S2 (crumbles) diets and their interaction [ T1 (P1S1), T2 (P1S2), T3 (P2S1) T4 (P2S2), T5 (P3S1) and T6 (P3S2)]. Result of the percent study could be summarized as follow: Broiler chicks feeding on feed program 3 (P3) reflected the highest significant results in both live body weight (LBW) and body weight gain (BWG) than chicks on the P1-2. Broiler chicks feeding on feed programs P2-3 were significantly less feed consumption (FC) and better energy conversion ratio (ECR), greater performance index (PI) and Eruption production efficiency factor (EPEF) than those on P1 program. Broiler feeding different feed form (S1-2) showed insignificant different in LBW, BWG, FC or feed conversion ratio (FCR). Broiler chicks fed T5 (P3S1) diets reflected the highest LBW and BWG, while the best FCR, Piand EPEF were detected for the chicks fed T3, T5, and T6 diets, respectively. The best economic efficiency value was demonstrated when broiler chicks were fed T5 (P3S1) diets, and the value was 19.0% higher compared to those fed T1 (P1S1) diets. In conclusion, feeding broiler chicks programs 3 (21%, 20% and 19%) diets, with shape (S1) feed from (crumble/pellet) upholding and reinforcement productive performance and economic efficiency. | ||||
