发酵五味子药渣对山西黑猪生长性能、血清生化指标及免疫功能的影响OA北大核心CSTPCD

The purpose of this experiment was to study the effects of fermented Schisandra dregs on growth performance,serum biochemical indexes,and immune function of Shanxi black pigs.Sixty 28-day-old Shanxi black weaned piglets were randomly divided into four groups with three replicates in each group and five weaned piglets in each replicate.In each group,0(control group),0.1％(experimental group Ⅰ),0.2％(experimental group Ⅱ),and 0.3％(experimental group Ⅲ)fermented Schisandra dregs were added to the basal diet,respectively.The pre-test period was seven days,and the formal test period was 21 days.The results showed that compared with the control group,the average daily gain of weaned piglets in experimental group Ⅱ and experimental group Ⅲ increased significantly(P＜0.05),and the feed to gain ratio decreased significantly(P＜0.05).The diarrhea rate of weaned piglets in all experimental groups decreased significantly(P＜0.05).Compared with the control group,the contentrations of serum albumin,total protein and blood glucose in all experimental groups increased significantly(P＜0.05),while the activity of aspartate-oxaloacetic aminotransferase decreased significantly(P＜0.05).The serum globulin content in the experimental group Ⅱ and experimental group Ⅲ increased significantly(P＜0.05),while the serum urea nitrogen content decreased significantly(P＜0.05).Compared with the control group,the serum levels of IgG,IgM,and IL-2 in all experimental groups were significantly increased(P＜0.05),and the serum levels of IgA in the experimental group Ⅱ and experimental group Ⅲ were significantly increased(P＜0.05).The results show that fermented Schisandra dregs can effectively improve the growth performance,reduce diarrhea rate,improve serum biochemical indexes and enhance immune function of weaned piglets,and the best results are achieved with a 0.3％addition rate.
