Abstract

This experiment was conducted to investigate the effect of peptides derived from sunflower seed meal on performance, carcass characteristics, and antioxidant activity in broiler chickens. In this experiment, 200 Ross 308 male broiler chicks were used in a completely randomized design with five treatments, four replicates, and 10 chicks in each replicate, for 26 days. Experimental treatments included: 1) Control diet without any additives, 2) Control diet + 300 mg vitamin E per kg diet, 3) Control diet + 250 mg sunflower seed meal peptides per kg diet, 4) Control diet + 500 mg sunflower seed meal peptides per kg diet, 5) Control diet + 1000 mg sunflower seed meal peptides per kg diet. There were significant differences among treatments in feed conversion ratio and body weight gain in grower and whole periods of the experiment (p<0.05). The mostt, and leastt body weight gain belonged to treatment 5, and control treatment. The least feed conversion ratio in grower and whole period was observed in treatment 5 (1.37 and 1.36) respectively (p<0.05). The effect of experimental treatments on carcass percentage was significant. The most carcass percentage belonged to treatment 5 (73.31%), and the least was observed in treatment 2 (68.37%) (p<0.05). The malondialdehyde concentration in breast and thigh meat in groups received different levels of peptides and in treatment 2 was lower than the control group. In conclusion, results of the present experiment, showed that sunflower seed meal peptides have antioxidant activity and improve performance, carcass characteristics, meat stability after slauthering,
