Abstract：To explore the effects of complex plant polysaccharides(Astragalus polysaccharide,Lycium barbarum ploysaccharide,Seaweed ploysaccharide)on the performance of sows and piglets,56 sows in late pregnancy of 2-3 parities were randomly divided into control group(basal diet)and three test groups(basal diet+0.05%,0.15%,0.25%complex plant polysaccharides).The test period was from 7 days before farrowing to 21 days after farrowing.The results showed that in the recovery of sow body condition,compared with the control group,backfat thickness at weaning of test groups 2 and 3 increased significantly by 7.48%and 8.09%,respectively,while there was no significant difference between the test group 1 and the control group.The backfat thickness loss was significantly reduced by 25.18%,51.08%,and 48.92%,respectively.Among them,the reduction of the test groups 2 and 3 were significantly greater than that of the test group 1.The estrus rate within 7 d post-weaning was significantly increased by 20.15%,35.07%and 37.08%,respectively.Among them,the increasing extent of the test groups 2 and 3 was signifianty greater than that of the test group 1.In terms of sow farrowing performance,compared with the control group,the number born alive in the test groups 1,2 and 3 increased significantly by 9.57%,14.41%and 11.70%,respectively;the number of healthy piglets was increased by 12.62%,16.41%and 14.46%,respectively,but there was no significant difference between the test group 1 and the control group.The newborn litter weight of piglets increased significantly by 10.50%,13.74%and 8.52%,respectively.The number of weak piglets was significantly reduced by 24.53%,27.36%and 23.58%,respectively.The number of stillbirths was significantly reduced by 16.20%,46.48%and 42.96%,respectively.In terms of serum immune performance of sows,compared with the control group,the IgA content in the test groups 1,2 and 3 increased significantly by 21.59%,19.32%and 18.18%,respectively;the IgM content of group 2 and group 3 was significantly increased by 21.10%and 23.85%,respectively,while the difference of group 1 was not significant.TNF-α levels were significantly reduced by 14.96%,19.44%,and 18.07%,respectively.The content of IL-2 increased significantly by 42.43%,45.91%and 48.68%,respectively.The content of IL-4 was significantly increased by 13.07%,14.86%and 14.08%,respectively.The content of IL-6 was significantly decreased by 18.52%,16.13%and 12.82%,respectively.In terms of growth performance of piglets,compared with the control group,the average birth weight of weaned piglets in the test groups 1,2 and 3 increased by 17.23%,19.43%and 19.59%,respectively.The weaning litter weight of piglets was significantly increased by 29.99%,38.68%and 34.29%,respectively,and the weaning litter weight of group 2 and group 3 was significantly higher than that of group 1.The average daily gain increased significantly by 20.97%,23.18%and 24.06%,respectively.The diarrhea rate was significantly reduced by 19.26%,26.91%and 28.89%,respectively,and the diarrhea rate of the test groups 2 and 3 was significantly lower than that of the test group 1.In summary,adding 0.05%,0.15%,0.25%complex plant polysaccharides to the sow diet can significantly improve the reproductive performance,immune function of sows and growth performance of piglets,and the improvement effect of 0.15%and 0.25%concentration groups is significantly better than that of low concentration group.
