In order to determine the role of the cecum on energy use in growing chickens, metabolizability of the dietary energy and energy expenditure were examined in the week following bilateral ligation and washing out of the cecum. Apparent metabolizable energy (AME) values were 14.30 and 13.69 kl/g air-dry matter for sham-operated and cecally ligated chickens, respectively. These values were found to be significantly different (P< 0.05). Although AME intake and fasting heat production were decreased by cecal ligation, the distribution of AME (measured as fasting and feeding heat production, as well as heat increment and energy retention, as a proportion of AME intake) was not affected. These results suggest that the cecum helps chickens extract AME from corn-soybean type diets with little, if any, effect on AME use, based on the present study of growing chickens in the week following cecal ligation.
