Effects of Fermented Traditional Chinese Medicine on Reproductive Performance and Lactation Performance of Sows,Growth Performance of Suckling Piglets
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]
