Changes of intestinal morphology in semi-commercial village chicken treated with effective microorganisms

Effective microorganisms have been proved to have beneficial effect in preventing infections, maintain intestinal microbial balance, improving digestion and absorption rate thus improving production. However, lack of study has been done on morphological changes of intestine caused by effective microorganisms.An experiment was conducted to determine the effects of supplementing diets with effective microorganisms on gross anatomy of the small intestine and intestinal morphological changes of semi-commercial village chickens. Sixteen male semi-commercial village chickens were assigned into two treatment groups, the control and treated group. A complete randomized design was used. The treated group was supplemented with effective microorganisms (EM-1) in drinking water throughout the experiment. Effective microorganism supplementation shows significantly difference of (P<0.05) the width of villi of the ileum. However, no changes in the height of villi (P>0.05) seen in the villi of ileum. Effective microorganism did not affect (P>0.05) the height and the width of the villi of the duodenum and jejunum. Besides, gross measurement of the small intestine of semi-commercial village chickens supplemented with effective microorganisms is significantly longer (P<0.05) compared to the control group. It is concluded that effective microorganism supplementation to the drinking water of sixteen semi-commercial village chicken increases the width of the villi in the ileum and causes longer small intestine.
