Abstract：To investigate the effects of adding fermented Chinese herbal medicines(Codonopsis pilosula,Lycium barbarum,Astragalus membranaceus,Atractylodes macrocephala,Poria cocos)to the diet of lactating sows on the growth performance,blood biochemical indexes,immune function and antioxidant capacity of lactating sows and suckling piglets,and to explore its application effects in lactating sows and suckling piglets,27 Hexi black sows with similar parity,farrowing time and litter size were randomly divided into 3 groups with 3 replicates per group and 3 piglets per replicate.The control group was fed a basal diet,while experimental groups Ⅰ and Ⅱ were supplemented with 1.5%and 2.0%fermented Chinese herbal medicines in the basal diet,respectively.The experimental period was from the date of delivery of sows to the end of weaning day of piglets at 25 days post partum.The results showed that compared with the control group,the weaning body weight per individual and average daily gain of experimental group Ⅰ were significantly increased by 11.16%and 12.53%,respectively.The diarrhea rates of the two experimental groups were significantly decreased by 67.60%and 85.73%,respectively.In experimental group Ⅰ,the activities of alanine aminotransferase,aspartate aminotransferase and blood urea nitrogen content in the blood were significantly decreased by 35.36%,40.11%and 24.96%,respectively.The contents of glucose in experimental groups Ⅰ and Ⅱ were increased by 65.06%and 94.58%,respectively.The contents of IgG,IgA and IL-6 in blood of group Ⅰ were significantly increased by 28.33%,44.95%and 24.68%,respectively.The levels of IL-1β and IL-6 in group Ⅱ were significantly increased by 35.44%and 33.73%,respectively.The activity of superoxide dismutase in the blood of group Ⅰ was significantly increased by 22.32%,and the content of malondialdehyde was significantly decreased by 32.61%.In summary,adding 1.5%fermented Chinese herbal medicines to the diet of lactating sows can effectively improve the growth performance of suckling piglets,reduce diarrhea rate,and optimize some blood biochemical and immune antioxidant indicators.
