Abstract

BACKGROUND: GLUTAMINE supplementation to the PRE-STARTER DIET of broiler chicks could improve their performance during the first week of post-hatch.OBJECTIVES: This experiment was conducted to evaluate the influence of GLUTAMINE levels in the PRE-STARTER DIET on intestinal mucosa MORPHOLOGY and performance of broiler chicks.METHOD: A total of 160 Ross 308, one-day old broilers were used in a complete randomized block design with 3 treatments of 5 replicates. Diets were formulated to contain different levels of GLUTAMINE (0, 0.5 and 1%). Body weight and feed intake were measured at 6 and 13d. On d 0, 3, 6 and 13 post hatch, 2 birds per each replicate were weighted and killed, and samples of the duodenum, jejunum, and ileum were taken subsequently.RESULTS: Supplementation of diets with 1% GLUTAMINE improved growth performance and feed efficiency at 6 and 13 day post hatch (p<0.05). On d 3 and 6, GLUTAMINE supplementation increased villi height and width in the SMALL INTESTINAL significantly (p<0.05). On d 13, chicks fed GLUTAMINE added diet had a longer villi height and width than those fed the basal diet (p<0.05). GLUTAMINE supplementation has also decreased crypt depth of jejunum and ileum at 3, 6 and 13, but increased crypt depth in duodenum at 3 and 6 d of age (p<0.05). Increase in GLUTAMINE levels of PRE-STARTER DIET increased villi height relative crypt depth of jejunum and ileum at 3 and 6 d of age. On d 13, chicks fed diet contain 1% GLUTAMINE had a higher villi height relative crypt depth than those fed the basal diet.CONCLUSIONS: Addition of 1% GLUTAMINE to the PRE-STARTER DIETs improved broiler growth performance and resulted in better development of the intestinal mucosa in broiler chicks.
