Abstract
To investigate the effects of adding traditional Chinese medicine preparations to the diet on reproductive performance,blood biochemical indicators,PRRS antibody levels,and vertical transmission of PRRSV in sows.Select 104 pregnant sows with similar physical conditions at 3 weeks before delivery(from a pig breeding and PRRS positive pig farm),and divide them into a control group and an experimental group according to the average number of buildings.The experimental group's diet is supplemented with tradi-tional Chinese medicine preparations(mainly Qiqing Baidu granules,Silver Yellow soluble powder,and Fragrant Mushroom Health),while the control group is fed a basic diet for 50 days.Result:Compared with the control group,the average number of live piglets per litter in the experimental group increased,while the number of ineffective piglets decreased significantly.The serum levels of ALT and AST decreased significantly(P<0.05),TBIL and other factors decreased slightly,but the difference was not significant(P>0.05);In terms of antibody detection against PRRS,the mean S/P value of the experimental group decreased,and the proportion of S/P>2.0 de-creased by 10%.In conclusion,the addition of Chinese medicine preparation to the sows'diet can improve their reproductive perfor-mance,reduce the incidence rate of piglets,maintain a stable level of PRRS antibody,and reduce liver and kidney function damage.关键词
