Present study was conducted to evaluate different strategies for feed formulation in commercial broiler production. A total of 16 male newly hatched broiler chickens (Gallus gallus domesticus) were fed with different formulated diets in 3 feeding phases, starter (1–11 d), grower (12-22 d) and finisher (23–33 d). Four strategies of feed formulation (F1, F2, F3 and F4) were compared; where in F1 group was fed with traditional diet, F2 and F3 were fed with traditional diet after supplementation with 10% & 20 % paneer respectively. The last group (F4) was fed with traditional diet supplemented with 10% collagen and is incorporated into paneer to provide extra protein. The collagen used in the study was analyzed and characterized by UV-Vis spectroscopy, SDS-PAGE and FTIR which was confirmed type-I collagen. All the experimental birds had shown significantly high body weight (BW) for F4 birds compared with other groups. Feed conversion ratio was significantly lower for F3 birds compared to the birds in other groups. No differences were detected for feed intake and mortality. At 33 d, F4 birds (2.227) were significantly heavier than other groups and a remarkable difference was noticed in the decreasing order F3>F2>F1 (2.004 kg, 1.998 kg and 1.749 kg respectively). Notable differences were detected for carcass yield (%), breast yield (%) and breast-to-carcass ratio at 33 d. In conclusion, our results demonstrated that the enhancement in growth rate of birds was observed by providing them with collagen along with the regular diet.
