Abstract: This study was conducted to investigate the effects of Chinese herbal compound fermentation powder (CHCF) on growth performance,nutrient apparent digestibility and digestive enzyme activities of weaned piglets.A total of 32 healthy 42-day-old weaned piglets (Duroc×Landrace×Large White) with an average body weight of (14.96±0.96) kg were randomly divided into 4 treatments,8 replicates per treatment,and 1 pig per replicate.The control group was fed the basal diet,and the other three groups were supplemented with chlortetracycline (CC) 75 mg/kg,CHCF 600 mg/kg,CC 75 mg/kg+CHCF 600 mg/kg.The experiment lasted for 42 days.The results showed as follow:Supplementation of CHCF had significantly increased the apparent digestibility of dry matter,organic matter and carbohydrates and the apparent digestible energy (ADE) (P<0.05),increased the apparent digestibility of essential amino acid and non-essential amino acid (Gly,Asp,Ala,Cys and Tyr),activities of lipase (duodenum,jejunum and ileum) and amylase (ileum) (P<0.05).CHCF and CC had a significant interaction on average daily gain (ADG) and ADE,the apparent digestibility of crude protein (CP) and ether extract (EE),and the apparent digestibility of Leu,Phe and Ser (P<0.05).Compared with control group,CHCF and CC group had significantly increased ADG and the apparent digestibility of CP and EE,the apparent digestibility of Phe and Ser (P<0.05),but there were no significant difference between two groups (P>0.05).In conclusion,the addition of 600 mg/kg CHCF in diets could improve the nutrient apparent digestibility,apparent digestibility of amino acid and intestinal digestive enzyme activities of weaned piglets.
