摘要

本试验旨在研究植物多酚对黄羽肉鸡抗氧化性能、肠道形态及肉品质的影响。选取1日龄雄性黄羽肉鸡288只，随机分为4组，每组6个重复，每个重复12只。各组分别饲喂基础饲粮（对照组）、基础饲粮+100 g/t抗敌素（抗生素组）、基础饲粮+500 mg/kg植物多酚（BP500组）和基础饲粮+1 000 mg/kg植物多酚（BP1000组）。试验期56 d。结果表明：1）21日龄时，BP500组和BP1000组肉鸡血清中过氧化氢酶（CAT）活性显著高于抗生素组（P<0.05）；56日龄时，BP1000组肉鸡血清中CAT活性显著高于其他3组（P<0.05）。2）21日龄时，BP500组和BP1000组肉鸡回肠绒毛高度/隐窝深度（V/C）显著低于抗生素组（P<0.05）；56日龄时，BP500组肉鸡回肠V/C显著高于对照组和抗生素组（P<0.05）。3）56日龄时，BP1000组胸肌肉色红度（a^*）值显著高于其他3组（P<0.05），BP500组和BP1000组胸肌失水率显著低于其他2组（P<0.05），BP500组和BP1000组胸肌24 h滴水损失显著低于其他2组（P<0.05），BP1000组胸肌48 h滴水损失显著低于对照组和抗生素组（P<0.05）。由此可见，饲粮添加500和1 000 mg/kg的植物多酚均能改善黄羽肉鸡肠道形态，提高机体的抗氧化能力，并改善鸡肉品质。植物多酚的推荐添加量为1 000 mg/kg。

Abstract

This experiment was conducted to investigate the effects of botanical polyphenol on antioxidant capacity, intestinal morphology and meat quality of yellow broilers. A total of 288 one-day-old male yellow broilers were selected and randomly allocated to 4 groups with 6 replicates per group and 12 chickens per replicate. Broilers in the four groups were fed a basal diet (control group), the basal diet+antibiotics (antibiotic group), the basal diet+500 mg/kg botanical polyphenol (BP500 group) and the basal diet+1 000 mg/kg botanical polyphenol (BP1000 group), respectively. The experiment lasted for 56 days. The results showed as follows: 1) on 21 days of age, the serum catalase (CAT) activity of BP500 group and BP1000 group was significantly higher than that of antibiotic group (P<0.05); on 56 days of age, the serum CAT activity of BP1000 group was significantly higher than that of other three groups (P<0.05). 2) On 21 days of age, the villous height/crypt depth (V/C) in ileum of BP500 group and BP1000 group was significantly higher than that of antibiotic group (P<0.05); on 56 days of age, the V/C in ileum of BP500 group was significantly higher than that of control and antibiotic groups (P<0.05). 3) On 56 days of age, the meat color of redness (a^*) value in breast muscle of BP1000 group was significantly higher than that of other three groups (P<0.05); the water loss rate of breast muscle of BP500 group and BP1000 group was significant lower than that of other two groups (P<0.05); the 24 h drip loss of breast muscle of BP500 group and BP1000 group was significant lower than that of the control group (P<0.05), the 48 h drip loss of breast muscle of BP1000 group was significant lower than that of control group and antibiotic groups (P<0.05). It is concluded that botanical polyphenol can improve intestinal morphology, antioxidant capacity and meat quality of yellow broilers. The recommended addition of botanical polyphenol is 1 000 mg/kg.

Key words： botanical polyphenol; yellow broilers; antioxidant capacity; intestinal morphology; meat quality
