辣木叶多糖对广西三黄鸡生长性能、免疫功能和血清生化指标的影响

Effect of Moringa oleifera leaves polysaccharide on growth performance,immune function and serum biochemical indexes of Guangxi Sanhuang chickens

试验旨在探讨在饲粮中添加不同比例的辣木叶多糖对三黄鸡生长性能、血清生化指标和免疫功能的影响。选取1日龄三黄鸡600羽,随机分成5组,每组8个重复,每个重复15羽三黄鸡。对照组(CON组)饲喂基础饲粮,T1组、T2组、T3组、T4组分别在基础饲粮添加0.08%、0.12%、0.16%、0.20%的辣木叶多糖。试验期42 d。结果显示,与对照组相比,1~21日龄,T1组、T2组、T3组三黄鸡的料重比显著降低(P<0.05),T3组42日龄三黄鸡的体重显著升高(P<0.05);1~42日龄,各试验组三黄鸡的料重比均显著降低(P<0.05)。与对照组相比,T2组血清白蛋白含量显著升高(P<0.05),T3组血清尿素氮含量显著降低(P<0.05);T1组、T2组、T3组血清葡萄糖含量显著增加(P<0.05);T3组胸腺指数显著升高(P<0.05),T1组、T3组、T4组血清白细胞介素-4(IL-4)含量显著升高(P<0.05),T2组、T3组血清白细胞介素-6(IL-6)含量显著降低(P<0.05),各试验组血清白细胞介素-1β(IL-1β)含量显著升高(P<0.05)。研究表明,添加辣木叶多糖能够改善三黄鸡的生长性能,促进免疫器官的发育,提高机体的免疫功能,改善蛋白质代谢,且添加量为0.16%时效果较好。

The experiment was to investigate the effect of different proportions of Moringa oleifera leaves polysaccharides on the growth performance,serum biochemical indexes and immune function of Sanhuang chickens.A total of 600 oneday-old Sanhuang chickens were randomly divided into five groups with eight replicates in each group and 15 chickens in each replicate.The chickens in the control group(CON group)were fed a basal diet,and the basal diet of group T1,group T2,group T3 and group T4 was supplemented with 0.08%,0.12%,0.16%and 0.20%Moringa oleifera leaves polysaccharides,respectively.The trial period was 42 days.The results showed that compared with the control group,the feed to gain ratio of Sanhuang chickens in the group T1,group T2 and group T3 from 1 to 21 days of age decreased significantly(P<0.05),and the body weight of Sanhuang chickens in group T3 at 42 days of age increased significantly(P<0.05).From 1 to 42 days of age,the feed to gain ratio of Sanhuang chickens in the experimental groups decreased significantly(P<0.05).Compared with the control group,the content of serum albumin in the group T2 increased significantly(P<0.05),while the content of serum urea nitrogen in the group T3 decreased significantly(P<0.05).The glucose content in serum of the group T1,group T2 and group T3 increased significantly(P<0.05).The thymus index of the group T3 increased significantly(P<0.05),the serum IL-4 content of the group T1,group T3 and group T4 increased significantly(P<0.05),the serum IL-6 content of the group T2 and group T3 decreased significantly(P<0.05),and the serum IL-1βcontent of the experimental groups increased significantly(P<0.05).The experiment indicates that adding Moringa oleifera leaves polysaccharides can improve the growth performance,promote the development of immune organs,improve immune function and improve protein metabolism of Sanhuang chickens,and adding 0.16%has the better effect.
