摘要
文章旨在探讨绞股蓝多糖对童鸽生长性能、血清免疫和抗氧化能力的影响。试验选取28日龄、体重相近[(441.08±35.63)g]的天成王肉鸽200只(雌雄各半),随机分为4组,每组5个重复,每个重复10羽(雌雄各5羽)。各组饲喂基础日龄的同时分别添加0、300、600、1200 mg/kg的绞股蓝多糖,预试期7 d,正试期28 d。结果表明,(1)与对照组相比,600 mg/kg组平均日增重显著提高31.58%(P<0.05);(2)600 mg/kg组和1200 mg/kg组血清免疫球蛋白A(IgA)、免疫球蛋白M(IgM)、白细胞介素-2(IL-2)、白细胞介素-4(IL-4)、补体3(C3)、干扰素-γ(IFN-γ)较对照组显著提高(P<0.05);(3)就血清超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH-Px)指标而言,600 mg/kg组和1200 mg/kg组较对照组均显著提高(P<0.05)。由此可见,在童鸽生长、免疫和抗氧化方面,绞股蓝多糖具有明显增强作用,本试验条件下绞股蓝多糖的添加为600 mg/kg较为适宜。
This experiment aimed to explore the effects of polysaccharides from Gynostemma pentaphyllum on the growth performance,serum immunity,and antioxidant capacity of young pigeons.A total of 200 Tiancheng King meat pigeons(half male and half female)at 28 days of age with similar body weight(441.08±35.63g)were selected and randomly divide into 4 fours,with 5 replicates in each group and 10 birds per replicate.The 4 groups were fed basal diets supplemented with 0,300mg/kg,600mg/kg,and 1200mg/kg Gynostemma pentaphyllum polysaccharides,respectively.The pre-trial lasted for 7 days,followed by a 28-day experimental period.The results showed that,compared with the control group,(1)the 600mg/kg group increased the average daily weight gain by 31.58%(P<0.05);(2)serum levels of IgA,IgM,IL-2,IL-4,complement C3,and INF-γin the 600mg/kg and 1200mg/kg groups were significantly higher than those of the control group(P<0.05);(3)serum SOD and GSH-Px activities in the 600 mg/kg and 1200 mg/kg groups were significantly increased(P<0.05).It can be seen that the additive of Gynostemma pentaphyllum polysaccharide in feed can improve the growth performance,enhance serum immunity and antioxidant capacity of young pigeons.Under the conditions of this experiment,adding 600mg/kg Gynostemma pentaphyllum polysaccharide has a better effect on young pigeons.
