摘要
选用135头体重约6 kg的“杜长大”三元杂交猪,根据体重相近、公母各半、随机的原则分为对照组和中药Ⅰ、Ⅱ组,每组3个重复,试验50 d.在基础日粮中添加2种不同精制中草药添加剂,研究其对断奶仔猪生产性能和免疫功能的影响.结果表明:中草药饲料添加剂能明显改善断奶仔猪的生产性能,与对照组相比较,总蛋白、白蛋白、球蛋白、免疫球蛋白(IgA、IgM、IgG)、补体(C3、C4)和血清中IL-2、γ-IFN含量均有显著提高(P<0.05);CD3、CD4、CD8数量均无显著变化(P>0.05),但CD4/CD8值变化极显著(P<0.01).可见精制中草药添加剂在一定程度上增强猪体免疫功能.
Two different kinds of compound Chinese herbal medicine feed additives were supplemented respectively to the same basic dietary to investigate the effect on the immune function and production performance of weaning piglets. A total of 135 crossed piglets ( D × L ×Y) with an average body weight of 6 kg were allotted to three groups by weight, sex and litter using a randomized complete block design, one was control group which was added with antibiotics and chemical compound drugs, and the other two were test groups which were added with Chinese herbal medicine feed additives Ⅰ , Ⅱ, respectively. There were 3 replicatios for each group. The feeding experiment lasted for 50 days. The results indicated that the daily gain, diarrhea ratio, complement ( C3 , C4 ), total protein (TP), albumin (ALB), immunoglobulin, acid α-anphthyl acetate asterase in lymphocyte (ANAE ^+) and interferon (γ- IFN), interleukin-2 (IL-2) in serum of treated weaning piglets significantly increased, as compared to the control group (P 〈 0.05 ), the ratio of CD4/CD8 was very significantly different (P 〈0.01 ) , but there was insignificant difference in CD3, CD4, CD8. It is concluded that Chinese herbal medicine feed additives could enhance the formation of immunoglobin, complement, γ-IFN and IL-2 to improve immune function.
