Abstract: 【Objective】 This experiment was conducted to investigate the effects of compound Chinese medicine fermentation powder on growth performance,nutrient apparent digestibility,antioxidant function and immune function in weaned piglets.【Method】 48 healthy crossbred and castrated weaned piglets (Duroc×Landrace×Yorkshire) of 28-day-old with similar initial body weight of (8.290±0.140) kg were randomly divided into 2 groups with 6 replicates per group and 4 pigs per replicate.Pigs in the control group were fed a basal diet,while the piglets in the experimental group was fed a basal diet containing 3% compound Chinese medicine fermentation powder.The compound Chinese medicine fermentation powder was fermented from Hawthorn,Tangerine peel,chicken’s gizzard-membrane,Chinese yam and Poria cocos,and its main active substances include organic acids,flavonoids,polysaccharides and triterpenoids.The trial lasted for 28 d,3 d before the end of the experiment,dietary and fecal samples were collected.At the end of the experiment,one weaned piglets with an average body weight were selected from each replicate for slaughter,plasma and liver were collected and growth performance,nutrient apparent digestibility,plasma and liver antioxidant indices and plasma immune indices were detected.【Result】 Compared with the control group,there were no significant differences in the average daily feed intake (ADFI) and the feed to gain ratio (F/G) of weaned piglets in the compound Chinese medicine fermentation powder group (P>0.05),but the average daily gain (ADG) was significantly increased (P<0.05),and the diarrhea rate was significantly decreased (P<0.05).Compared with the control group,the apparent digestibility of ether extract (EE) and ash (Ash) and calcium (Ca) in the compound Chinese medicine fermentation powder group were extremely significantly or significantly increased (P<0.01;P<0.05).Compared with the control group,the plasma catalase (CAT) and glutathione peroxidase (GSH-Px) activities and the total antioxidant capacity (T-AOC) of weaned piglets in compound Chinese medicine fermentation powder group were significantly or extremely significantly increased (P<0.05;P<0.01).Furthermore,the activity of total superoxide dismutase (T-SOD) in liver of piglets in the compound Chinese medicine fermentation powder group was significantly higher than that of control group (P<0.05).Compared with the control group,the content of immunoglobulin A (IgA) and immunoglobulin M (IgM) in plasma of piglets in the compound Chinese medicine fermentation powder group were significantly increased (P<0.05),while the content of tumor necrosis factor-α (TNF-α) was significantly decreased (P<0.05).【Conclusion】 Adding 3% compound Chinese medicine fermentation powder in the basal diet could improve the apparent digestibility of EE,Ash and Ca,improve the antioxidation capacity and enhance the immune function of the body,thereby reducing diarrhea rate and improving the growth performance of weaned piglets.
