| Abstract | ||
| This study was conduced at the poultry farm, Animal Resource Department, Collage of Agriculture, University of Baghdad from 20-4-2010 to 4-6-2010, to investigate the potential effect of coriander oil on intestine histometrical traits in broiler . One hundred and thirty five Arbor acers day-old broiler chicks were randomly assigned in to three dietary treatments with three replicate pens per trearment (15 birds/pen). Birds were fed experimental diets containing 0%,0.5% and 1% coriander oil. Water and feed were provided ad libitum during the six weeks experimental period. Three experimental birds were taken randomly from each treatments at 42 day and anesthetized by using chloroform inhalation in closed chambers and then the necropsy were applied to removed the small intestine. Histological technique were applied on each samples and also the ocular micrometer were used to measured the thickness of the intestinal wall layers. Results showed that feed conversion ratio were significantly (p<0.05) higher in the (T2 and T3) as compared with control treatment. Chicks in (T2 and T3) had significantly (P<0.05) higher thickness in duodenum wall than control (T1), but the mucosal layer thickness were more significantly (P<0.05) in (T3) . The jejunum wall and mucosal layer thickness were significantly (P<0.05) higher in (T2) group. While chicks in (T3) had significantly (P<0.05) higher wall and mucosal layer thickness in ileum compared with T1 and T2 . In conclusion the results showed that the increase in the intestinal wall thickness indicate that the intestine is highly activated in digestion and absorption function that lead to increase of feed conversion ratio. | ||
