摘要
为了研究日粮中不同比例的绞股蓝对断奶仔猪免疫功能的影响,选取240头21日龄的断奶仔猪,并将该实验动物随机分组为对照和试验I、Ⅱ、Ⅲ共4个处理组,每组3个重复,每个重复20头猪,公母各半.对照组饲喂基础日粮,3个试验组在基础日粮的基础上分别添加不同比例的绞股蓝,分别为0.5%、1.0%、2.0%,试验期为28 d.结果表明:日粮中添加0.5%、1.0%绞股蓝能够显著提高免疫球蛋白IgA、IgG、IgM以及补体C3、C4含量,同时免疫蛋白均升高,血清中抗氧化能力不同程度的提高,丙二醛的含量显著降低,并且免疫蛋白、血清中抗氧化能力和丙二醛与对照组相比均具有显著性差异(P<0.05).日粮中添加2%绞股蓝和对照组相比两者之间差异不显著(P>0.05).综合来看以添加1%绞股蓝作为一种中草药饲料添加剂饲喂家畜效果最好.
The aim of this study was to investigate effects of rations containing Gyrtostemma on the immune functions of weaning piglets.A total of 240 piglets at 21days old were selected and assigned randomly into four groups,with three replicates in each group and 20 pigs in each replicate(half male and half female).The piglets in each group had statistically nonsignificantly different body weight.The piglets in the control group were fed basal ration.The piglets in group I,group II and group Ⅲ were fed the basal ration supplemented with Gyrtostemma at 0.5%,1.0% and 2.0% ration respectively.The trial period was 28 d.The results showed that serum levels of total IgA,IgG,IgM and C3 and C4 rose with the increasing level of Gyrtostemma at 0.5%,1% in ration,which were significantly different from control group and group Ⅲ.Ration on performance,antioxidant capacity and immune function had significant difference(P<0.05).The rations supplemented with Gyrtostemma at 2.0%.were not significantly different from the control group(P>0.05).On the whole,the rations supplemented with Gyrtostemma at 1.0%.had the best effects on the weaning piglets.
