Abstract:
The present investigation was conducted to explore the effect of Selenium-enriched yeast supplement on the gross morphology and morphometry of the small intestine during post-hatch growth of chicken. Total eighty numbers of day-old broiler chicks were procured from the authorized breeder and were grouped into control and treatment groups. Each group had four replicates and each replica had ten birds. Selenium-Yeast was mixed with the standard diet of the treatment group at the dose rate of 0.15mg/kg feed. The samples were collected on the 14th and 28th day of the experiment. Results showed that the average body weight gain was higher in the dietary Se-Yeast supplemented group than the control group on both the days of experiments. The average length of the small intestine was increased significantly (p<0.05) with the age of both groups. However, when compared between groups, there were significant (p<0.05) changes on the 14th day but no difference on the 28th day. The average length of the duodenum and jejunum increased significantly (p<0.05) with age. When compared between groups, in case of the duodenal length, no significant (p<0.05) difference was found; however, the jejunum showed the opposite result on both the days of the experiment. The ileal average length was more on day 14th. There was no significant (p<0.05) difference in length of the ileum between the days and between the groups. The average diameter of jejunal and ileal Peyer’s patches had increased with increasing age but no significant differences (p<0.05) were noticed between the days and also the groups. In comparison, the diameter of Peyer’s patches of the jejunum was higher than the ileum on all days of studies. In conclusion, the Se-yeast had an effect on the small intestine as it increased the length resulting in weight gain and better FCR. The diameter of Peyer’s patches of both jejunum and ileum was increased as compared to the control group of birds which ultimately enhanced the better health development and production.
