摘要： To explore the effects of cordyceps militaris (CM) on growth performance and intestinal epithelium functions, 180 weaned pigs were randomly assigned into 5 treatments with 6 replicate pens per treatment (6 pigs per pen). Pigs were fed with basal diet (control) or basal diet supplemented with 100, 200, 400, and 800 mg/kg CM. The trial lasted for 42 d, and pigs from the control and optimal-dose groups (based on growth performance) were picked for blood and tissue collection (n = 6). Results showed that CM elevated the average daily gain (ADG) and decreased the ratio of feed intake to gain (F:G) in the weaned pigs (P < 0.05). CM supplementation at 100 mg/kg improved the digestibilities of dry matter (DM), crude protein (CP), and gross energy (GE) (P < 0.05). CM not only increased the activities of superoxide dismutase (SOD), glutathione (GSH), and catalase (CAT) but also increased the concentration of interleukin-10 (IL-10) in serum (P < 0.05). The serum concentrations of malondialdehyde (MDA), d-lactate, and diamine oxidase (DAO) were reduced by CM (P < 0.05). Interestingly, CM elevated the villus height and the ratio of villus height to crypt depth in the duodenum and jejunum and increased the activities of duodenal sucrase and maltase (P < 0.05). Moreover, CM elevated the expression levels of tight-junction proteins ZO-1, claudin-1, and occluding, as well as critical functional genes such as the fatty acid transport protein (FATP1), cationic amino acid transporter 1 (CAT1), and NF-E2-related factor 2 (Nrf2) in the duodenum and jejunum (P < 0.05). Importantly, CM increased the concentrations of acetic acid and butyric acid, and elevated the abundances of Bacillus and Lactobacillus in the cecum and colon, respectively (P < 0.05). These results indicated potential benefits of CM in improving the growth of weaned pigs, and such effect may be tightly associated with improvement in antioxidant capacity and intestinal epithelium functions.
