Title : Effects of dietary organic acid supplementation on the intestinal mucosa in broilers
Authors : S. KUM, U. EREN, A.G. ONOL, M. SANDIKCI
Summary : The aim of this study was to investigate some histological intestinal modifications induced by a dietary organic acid supplementation in broilers. Forty eight male Ross 308, one day old broilers were randomly allotted in 2 equal control and assay groups: whereas control birds were not supplemented, organic acids were added to the ration of the assay birds and the half of each group were euthanized at 21 days then at 42 days for semi-quantitative histological assessment of the small intestine mucosa (duodenum, jejunum and ileum) throughout Crossman's triple stain and periodic acid Schiff (PAS) stain. It was observed that organic acid supplementation markedly increased the intestinal absorption area by promoting villus growth in height and in width at 21 and 42 days. In parallel, the goblet cell counts were also significantly higher in treated group whatever the intestinal segment. Moreover, the induction of these histological modifications appeared early (before the 21st day), transient in duodenum and jejunum but prolonged (after the 21st day) in the ileum part since the magnification rates calculated for ileum villi in supplemented birds for the 21-42 days period were significantly higher than in controls. These results demonstrate a positive effect of organic acids on intestinal mucosa.
