| Summary : | In this study, determination of the effect of heat stress and use of Saccharomyces cerevisiae or (and) bacitracin zinc against heat stress to the height, width of villi and the goblet cell count per unit length of the duodenum, jejunum and ileum in quails was aimed. In this study, 47 56-day old Japanese quails were used. In the serial sections obtained from the intestinal samples the height and widths were measured and the goblet cell count per unit length of the villi determined with the aid of a image analysis program. The height of the villus in the duodenum, jejunum and ileum of the birds exposed to heat stress were shortened and the fall in goblet cell count per unit length in the villi of the ileum was found to be statistically significant whilst that in the duodenum and jejunum were not statistically significant. It was found that in those treated with yeast against heat stress the height of the villi in the jejunum was shortened, in those treated with bacitracin zinc the goblet cell count in the duodenum and jejunum increased, whereas in those treated with yeast- bacitracin zinc the villus height in the jejunum and ileum were found to be shorter with increased goblet cell count. In the combined use of yeast and bacitracin zinc, the individual effects were observed without any synergistic effect found. |
