| Abstract |
An experiment was conducted to evaluate the effects of dietary glutamine (Gln) and arginine (Arg) supplementation on performance, intestinal morphology and ascites mortality in broilers. A total of 675 day old chicks were randomly allocated to 9 experimental groups in a 3×3 factorial arrangement based on a completely randomized design with 5 replicates of 15 chicks. Three levels of dietary Gln (0, 0.5 and 1%) and Arg (100, 130% and 160% of Ross recommendation) supplementation were used in ascites inducing condition (15±1 ˚C) from 7 to 42 days of age. Dietary supplementation of Gln increased body weight gain (BWG) during grower, finisher and total periods (P<0.05) and increased feed intake during total period. Ascites mortality was decreased by Gln supplementation (P<0.05). Gln supplementation increased the villus height (VH) and crypt depth (CD) in duodenum and jejunum, and decreased the muscular layer in jejunum and ileum segments (P<0.05). Arg supplementation decreased CD in duodenum and jejunum and increased ileum villus width (VW), villus height /crypt depth ratio (VH/CD) in duodenum and jejunum and also muscular layer in duodenum, jejunum and ileum (P<0.05). Both Gln and Arg increased the goblet cell number (GCN) in duodenum whereas Gln supplementation decreased GCN in jejunum and ileum (P<0.05). The Gln×Arg interaction were observed for VH, VW, CD, VH/CD, muscular and serous layer thickness. It was concluded that dietary 0.5% Gln along with 130% Arg of Ross requirement, improve the intestinal morphology and performance and hence decrease the ascites mortality in broiler chickens with cold induced ascites. |
