Broiler chickens were weighed and feed intake per pen was recorded on d 1, 21, 35, and 42 of the experiment, and feed to gain ratio (F:G) was calculated. At 21 and 35 d of age, individual broiler chickens were weighed, and 2 broiler chickens per pen, closest to the mean, were selected and killed by carbon dioxide.
The gastrointestinal tract was immediately removed from broiler chickens on the control and 100mg/kg of clove, and the small intestine was then separated.
The ileum was defined as the region comprised between Meckel’s diverti- culum and the ileocecal junction.
