  • 摘要:150 day old Vencobb broiler chicks were randomly allocated to 5 treatment groups with 3 replicates of 10 chicks in each to determine the effect of mannan oligosaccharide (MOS) and Saccharomyces cerevisiae in gut morphology of broilers. The trial lasted for 6 weeks. For microscopic examination the representative samples of each segment of intestine were collected and fixed in the 10% buffered formalin. No significant difference was observed in treatments at length of different segments of intestine and villus height/crypt depth ratio. Significant (P< 0.05) difference observed for the mean height of the duodenum, jejunum, and ileum villus amongst different dietary treatments, being highest in T5 and lowest in T2. Mean crypt depth of the duodenum and ileum villus also differed significantly (P< 0.05) amongst treatments. The highest mean crypt depth in the duodenum was recorded in T5 and lowest in T2 whereas the highest mean crypt depth of caecum was recorded in T3 and the lowest in T1. Thickness of tunica muscularis was significantly (P< 0.05) decreased in all segments of intestine except colorectum as MOS and S. cerevisae added to the diet. Height of the epithelium of villi differed significantly (P< 0.05) amongst treatments in all segments of intestine except caecum being maximum in T5 and minimum in T2. It was concluded that supplementation of MOS and S. cerevisiae improves the gut health of broiler chickens.
