AB  - The experiment was conducted to determine influence of caecectomy on Endogenous Amino Acid Losses (EAAL) in unfed Rohde Island Red adult cockerels. During the experimental period (48 h), excreta of cockerels were collected and dried, ground and assayed for quantities of amino acids. The caecectomy increased (p<0.05) the endogenous quantities of serine, histidine, arginine, cystein and isoleucine and decreased (p<0.05) the endogenous quantities of methionine, lysine and leucine, but had no significant influence (p>0.05) on the endogenous quantities of aspartic acid, Glutamic acid, glycine, threonine, alanine, tyrosine, valine and phenylalanine. However, the mean quantity of EAAL in caecectomized cockerels was approximately 10% more than it in intact cockerels (p<0.05).
