This study was conducted to investigate the effects of dietary supplementation with fermented tradi-tional Chinese medicine on reproductive performance,lactation performance of sows,and growth performance of suckling piglets.Forty-five Landrace x Large White binary hybrid sows(1 week before farrowing)with 3 to 4 parity and similar body weight were randomly divided into 3 groups with 15 replicates per group and 1 sow per replicate.The control group was fed a basal diet,and the experimental groups were fed the basal diet sup-plementation with 2％and 4％fermented traditional Chinese medicine,respectively.These diets were fed from prenatal 7 days to postnatal 21 days.The results showed as follows:1)compared with the control group,diet-ary supplementation with 2％and 4％fermented traditional Chinese medicine significantly increased the birth litter weight,weaning litter weight,average weaning weight,weaned piglet number and the average daily gain of piglets(P＜0.05).2)Compared with the control group,dietary supplementation with 2％and 4％fermen-ted traditional Chinese medicine significantly increased the lactation capacity of sows and the contents of milk fat and milk protein in colostrum components(P＜0.05);significantly increased superoxide dismutase(SOD)activity(P＜0.05),and significantly decreased malondialdehyde(MDA)content in colostrum(P＜0.05).3)Compared with the control group,dietary supplementation with 2％and 4％fermented traditional Chinese med-icine significantly increased total antioxidant capacity(T-AOC)and SOD activity(P＜0.05),significantly de-creased MDA content in sow serum(P＜0.05);and significantly increased the contents of prolactin(PRL),estradiol(E2)in serum(P＜0.05),significantly decreased progesterone(Prog)content in sow serum(P＜0.05).4)Compared with the control group,dietary supplementation with 2％and 4％fermented traditional Chinese medicine significantly increased the serum SOD activity of suckling piglets(P＜0.05),and significant-ly decreased the diarrhea rate of piglets(P＜0.05).In conclusion,dietary supplementation with 2％and 4％fermented traditional Chinese medicine can significantly improve the reproductive performance and lactation performance of sows,and the growth performance of suckling piglets,decrease the diarrhea rate of piglets.[Chinese Journal of Animal Nutrition,2024,36(4):2234-2245]
