葡萄籽原花青素对樱桃谷肉鸭生长性能、免疫功能和抗氧化能力的影响

Effects of grape seed proanthocyanidins on growth performance,immune function and antioxidant capacity of cherry valley ducks

文章旨在研究葡萄籽原花青素(GSPs)对樱桃谷肉鸭生产性能、免疫功能和抗氧化能力的影响。试验将480只体重相近、健康的1日龄樱桃谷肉鸭随机分成4组,每组6个重复,每个重复20只鸭。空白对照组饲喂基础日粮,其他各组分别在基础日粮中添加50、75和100 mg/kg的葡萄籽原花青素。结果显示,(1)在平均日采食量(ADFI)和平均日增重(ADG)方面,与对照组相比,75 GSPs组、100 GSPs组樱桃谷肉鸭均显著高于对照组(P<0.05)。(2)与对照组相比,添加75 mg/kg GSPs樱桃谷肉鸭血清中免疫球蛋白G(IgG)和肿瘤坏死因子-α(TNF-α)含量显著降低(P<0.05)。(3)与对照组相比,添加不同含量GSPs各组血清过氧化物酶(CAT)和总抗氧化力(T-AOC)显著提升(P<0.05),75 GSPs组和100 GSPs组的谷胱甘肽过氧化酶(GSH-Px)和血清超氧化歧化酶(SOD)均显著提高(P<0.05),血清丙二醛(MDA)浓度显著降低(P<0.05)。研究表明,在樱桃谷肉鸭日粮中添加葡萄籽原花青素可提高樱桃谷肉鸭的ADG,增强免疫功能,改善抗氧化能力,日粮中葡萄籽原花青素添加量75 mg/kg效果较好。

The experiment was conducted to study the effects of grape seed proanthocyanidins(GSPs)on performance,immune function and antioxidant capacity of Cherry Valley ducks.Four hundred and eighty one-day-old cherry valley ducks with similar body weight and health status were randomly divided into 4 groups with 6 replicates in each group and 20 replicates in each group.groups with 6 replicates in each group and 20 ducks in each repetition.The control group was fed with basal diet,and the other groups were fed with GSPs of 50,75 and 100 mg/kg respectively.The results showed that:(1)compared with the control group,the average daily feed intake(ADFI)and average daily gain(ADG)of 75 gsps Group and 100 gsps group were significantly higher than those of the control group(P<0.05).Compared with the control group,the levels of IgG and TNF-αin the serum of Cherry Valley Ducks supplemented with 75mg/kg GSPS decreased significantly(P<0.05),and the levels of IgG and TNF-αin the serum of Cherry Valley Ducks supplemented with 75 mg/kg GSPS decreased significantly(P<0.05),Compared with the control group,Cat and T-AOC were significantly increased in the GSPS groups,while the activities of SOD and GSH-Px were significantly increased in the 75 GSPs and 100 GSPs groups(P<0.05),and the concentration of Malondialdehyde(MDA)was significantly decreased in the 75 GSPs and 100 GSPs Glutathione peroxidase groups(P<0.05)The results showed that adding GSPs to the diet of Cherry Valley Ducks could improve the daily gain,immunity and antioxidation ability of Cherry Valley ducks.The effect of GSPs 75 mg/kg in the Diet was better.
