ABSTRACT
The aim of this study was to investigate the effects of glutamine (Gln) on the intestinal mucosal structure and immune cells of broilers infected with Salmonella Enteritidis. 160 1-d-old commercial Arbor Acres (AA) broilers were randomly selected to receive one of four treatments, each of which had 5 replicates. Each replicate consisted of 8 chicks subjected to a 21-d feeding trial. Group I served as the unchallenged (CON). All birds in groups II (SCC) - IV were challenged with 2.0 × 104 CFU/mL of S. Enteritidis. The birds in groups III and IV were treated with 0.5% and 1.0% Gln. The results showed that S. Enteritidis infection led to a decrease in the relative length and weight, villus heightcrypt depth (VHCD) of the jejunum and ileum, the number of intraepithelial lymphocyte cells, and number of goblet cells and an increase in the number of mast goblet cells compared with the measurements of these parameters in the CON group (p 0.05). In addition, the Gln groups had increased relative length and weight, VHCD of the jejunum and ileum, numbers of intraepithelial lymphocyte cells, and numbers of goblet cells and decreased crypt depth in the jejunum and ileum and numbers of mast goblet cells compared with the measurements of these parameters in the SCC group (p 0.05). It was concluded that Gln added to broiler diets can effectively alleviate the intestinal mucosal damage caused by S. Enteritidis infection and improve its normal defense barrier function.(AU)
