Dietary glutamine supplementation enhances expression of ZO-1 and occludin and promotes intestinal development in Min piglets

Forty-eight Min piglets at 7 days of age were randomly divided into two groups which were fed with 0% and 0.8% glutamine, respectively. Supplementation with 0.8% l-glutamine, the average daily gain (ADG) were significantly increased, and the concentrations of glutamine, glutamate, arginine and citrulline in plasma were significantly improved (P < .05). The expression of jejunal mucosa glutathione peroxidase (GSH-Px) and total superoxide...
