摘要: 试验旨在探讨日粮中葡多酚对肉鸡生产性能和免疫机能的影响。选用1日龄健康爱拔益加(AA)肉仔鸡公雏鸡240只,随机分配到对照组及试验Ⅰ、Ⅱ、Ⅲ组4个处理组中,空白对照组饲喂基础日粮(不含葡多酚),试验Ⅰ、Ⅱ、Ⅲ组分别在基础日粮中添加葡多酚7.5、15、22.5 mg/kg,试验期42 d。结果表明,在0~3周龄,试验Ⅲ组采食量最高,生长速度较快;在3~6和0~6周龄,试验Ⅰ组日增重和饲料效率最佳,而试验Ⅱ组略低于对照组。葡多酚对肉仔鸡的免疫器官发育无显著影响,7.5 mg/kg葡多酚有增加肉仔鸡外周血中CD3+、CD8+、αβ和γδ T细胞数量的潜力。因此,肉仔鸡日粮中添加适量葡多酚可促进生长,调节免疫机能。

Abstract: This experiment was conducted to investigate the effects of dietary grape procyanidins on growth performance and immune function in broiler chickens. Two hundred and forty day-old Arbor Acre male broiler chickens were randomly allotted into four dietary treatments with different inclusion ( 0,7.5,15 or 22.5 mg/kg) of grape procyanidins. The experiment period lasted for 6 weeks. The results showed that chicks fed higher dose of grape procyanidins intake more feed and grew faster during the first 3 weeks. During the second 3 weeks and the whole 6 weeks,chicks fed 7.5 mg/kg grape procyanidins had higher body weight gain and superior feed efficiency,and chicks fed 15 mg/kg grape procyanidins diet had inferior growth performance compared to the controls. Dietary grape procyanidins did not affect the growth of the immune organs. The percentages of CD3+,CD4+,CD8+,αβ and γδ T lymphocytes in peripheral blood had the increased tendency in chicks fed 7.5 mg/kg grape procyanidins. Overall,optimal dose of grape procyanidins in the diet would stimulate late growth and modulate immune function in broiler chickens.
