Effects ofSophora alopecuroides Seed Dreg,Bifidobacterium bifidum and Lactobacillus salivaris Synbiotics on Seral Biochemical Indexes and Immunoglobulins in Early-weaned Piglets
摘要
Abstract
To get better known the effect of Sophora alopecuroides seed dreg,Bifidobacterium bifidum and Lac-tobacillus saliva on seral biochemical indexes and immunoglobulins of early-weaned piglets,60 Duroc×Landrace× Edelschwein three-cross weaning piglets at 21 days with similar weights were randomly chosen and divided into four groups.Every group practiced three repetitions and five piglets were tested in one repetition.The piglets in control group were fed with basal diet,while the piglets in test groups were respectively added 5 g/kg,10 g/kg and 20 g/kg of symbiotics in the basal diet.The test cycle was four weeks.One weaned piglet from each replicate was randomly selected and 5ml blood sample was collected when they were 28,35,42 and 49 days,seral biochemical in-dexes and immunoglobulin content of sera were measured by automatic analyzer and ELISA method.The results showed that compared with control group,it significantly improved the content of TPO,ALB and GLB(P<0.05)in the sera of early-weaned piglets of 42 days old that adding synbiotics in the feed and significant-ly reduced the content of ALT (P <0.01)in the sera of early-weaned piglets of 49 days old,but it had no effect on CHO(P >0.05).When it was 42 days old,the group of adding 20 g/kg of synbiotics significantly improved the concentration of AST in sera(P <0.01).Compared with control group,the groups of adding synbiotics could significantly improve the titers of IgM,IgG and IgA in early-weaned piglet sera(P <0.01),while the titers of IgM,IgG and IgA in the group of adding 20 g/kg of synbiotics were much lower than that in the control group when it was 35 days old(P <0.01).The results indicated that Sophora alo-pecuroides seed dreg,Bifidobacterium bifidum and Lactobacillus salivaris synbiotics added in the feed would have a positive effect on improving the biochemical indexes in serum and humoral immunity of early-weaned piglets.Obviously,the groups adding 5 g/kg,10 g/kg of synbiotics had more significant effects than that adding 20 g/kg of synbiotics in early weaned piglets.关键词
