(Table 2) in the birds fed organic acids in the diet.
These results are in concordance with the reports of earlier
researchers [23, 24] who reported that the supplementation
of organic acids improved the feed conversion ratio in
broiler chicken. The carcass characteristics of broiler chicken
fed diets supplemented with the organic acids showed no
significant differences (P > .05) between various treatment
groups (Table 2), confirming the earlier findings [25].
The mean values regarding the histomorphological alterations
in the broiler chicken fed organic acid based diets
are given in Table 3. Dietary supplementation of organic
acids significantly (P < .05) increased the villus height
in the duodenum, jejunum, and ileum but the values
were significant (P < .05) only in the duodenum and
jejunumwhen compared with the control group. The highest
duodenal, jejuna, and ileal villus heights were recorded in
the birds fed diets supplemented with 3% butyric acid, 3%
