中药制剂对母猪繁殖性能、血清生化指标和免疫相关指标的影响

Effects of traditional Chinese medicine preparations on reproductive performance,serum biochemical indices and immune-related indices in sows

旨在研究日粮添加中药制剂对母猪繁育性能、血清生化指标和免疫相关指标的影响。选择40头体况相近的9月龄左右母猪(来自猪繁殖与呼吸综合征阳性猪场),随机分为对照组和试验组,试验组日粮中添加1%的中药制剂(主要原料为七清败毒颗粒和香菇健),对照组饲喂基础日粮,试验周期150 d。结果:与对照组相比,试验组母猪配种率、分娩率、窝均活仔数有所上升,血清谷草转氨酶、谷丙转氨酶、总抗氧化能力、超氧化物歧化酶酶活性和丙二醛、葡萄糖、尿素氮含量无显著差异(P>0.05),血清免疫球蛋白A、免疫球蛋白G在第30天显著提高(P<0.05);猪繁殖与呼吸障碍综合征病毒(PRRSV)抗体检测方面,在第30天,试验组S/P均值显著降低(P<0.05),对照组和试验组的离散度分别为66.29%和50.74%;PRRSV抗原检测方面,第30天试验组阳性率由20%降至0。综上,在母猪日粮中添加1%的中药制剂能提升其繁殖性能和部分免疫指标,维持PRRSV抗体水平稳定,并能降低PRRSV抗原阳性率。

This experiment aimed to determine the effects of adding traditional Chinese medicine preparations to the diet on the reproductive performance,serum biochemical indices and immune-related indices in sows.Forty sows at around 9 months of age with similar body conditions were randomly divided into 2 groups,namely the control group and the experimental group.The experimental group had 1%traditional Chinese medicine preparation added to the diet,while the control group was fed with basic diet.The experimental period was 150 days.The results showed that,compared with the control group,the mating rate,delivery rate,and average number of live offspring per litter increased in the experimental group.There were no significant differences,however,in serum aspartate aminotransferase,alanine aminotransferase,total antioxidant capacity,superoxide dismutase activity,propylene glycol,glucose,and urea nitrogen levels(P>0.05),but the serum immunoglobulin A and immunoglobulin G levels were significantly increased on the 30th day(P<0.05).In terms of porcine reproductive and re-spiratory syndrome virus(PRRSV)antibody testing,on the 30th day,the S/P mean of the experimental group significantly decreased(P<0.05),and the dispersion of the control group and the experimental group were 66.29%and 50.74%,respectively.In terms of PRRSV antigen testing,the positive rate of the experimental group decreased from 20%to 0 on the 30th day.In conclusion,adding 1%traditional Chinese medicine preparation to the diet of sows had the effect of improving the breeding performance of gilt,enhancing some immune indicators,maintaining the stability of PRRSV antibodies in the pig population,and reducing the positive rate of PRRSV antigens.
