Abstract The objective of the present experiment was to evaluate the effect of bioactive peptides derived from cottonseed (BPC) on chicken performance, immunity, the total antioxidant activity of serum and intestinal morphology. A total of 280 one-day-old male broiler chicks (Ross 308) were randomly allocated into 1 of the following 7 experimental treatments (5 replicates per treatment with 8 broilers per pen). Five diets were formulated to contain 0 (control), 3, 4, 5 and 6 g BPC/kg of diet in comparison with control + 50 U excessive dietary vitamin E and control + 2 mg lincomycin. At 40 d the BW tended to improve in broilers supplemented with an antibiotic, 3, 5 and 6 g BPC/kg groups (p > .05). In the whole trial, supplementing 5 g BPC/kg increased feed intake of broilers in comparison to other groups (p < .05). In the whole trial broilers fed diets supplemented with 6 g BPC/kg had a significantly better FCR value (p < .001). Supplementation of 3 g BPC/kg increased antibody titres against Newcastle disease virus and sheep red blood cell (p < .01). Dietary supplementation of vitamin E, antibiotic, 3, 4 and 5 g BPC/kg significantly (p < .001) increased total antioxidant activity of serum compared with those fed the basal diet. In conclusion, the results indicated that supplementation of 6 g BPC/kg in broiler diets could induce favourable influences on growth performance, immune responses and total antioxidant activity of serum and it could be used in broiler diets as an alternative to antibiotics. HIGHLIGHTS Broilers fed diets supplemented with 6 g bioactive peptides (BPC)/kg had better FCR. Supplementation of BPC increased humoral immune responses.

棉籽生物活性肽对肉鸡生长性能、胴体性状、免疫力、血清总抗氧化活性和肠道形态的评价

摘要 本实验的目的是评估棉籽生物活性肽(BPC)对鸡性能、免疫力、血清总抗氧化活性和肠道形态的影响。总共 280 只 1 日龄雄性肉鸡(Ross 308)被随机分配到以下 7 个实验处理中的 1 个(每个处理 5 个重复,每栏 8 只肉鸡)。与对照 + 50 U 过量膳食维生素 E 和对照 + 2 mg 林可霉素相比,五种饮食被配制为含有 0(对照)、3、4、5 和 6 g BPC/kg 饮食。在 40 天时,肉鸡补充抗生素、3、5 和 6 g BPC/kg 组的 BW 趋于改善(p > .05)。在整个试验中,与其他组相比,补充 5 g BPC/kg 增加了肉鸡的采食量(p < .05)。在整个试验中,肉鸡饲喂补充 6 g BPC/kg 的日粮具有明显更好的 FCR 值(p < .001)。补充 3 g BPC/kg 可增加抗新城疫病毒和绵羊红细胞的抗体滴度(p < .01)。与喂食基础饮食的人相比,饮食中补充维生素 E、抗生素、3、4 和 5 g BPC/kg 显着 (p < .001) 增加了血清的总抗氧化活性。总之,结果表明,在肉鸡日粮中添加 6 g BPC/kg 可以对生长性能、免疫反应和血清总抗氧化活性产生有利影响,并且可以在肉鸡日粮中作为抗生素的替代品。亮点 肉鸡饲喂添加 6 克生物活性肽 (BPC)/kg 的日粮具有更好的 FCR。
