Extract

Cotton is one of the main agricultural crops of Iran. The potential of cottonseed meal (CSM) for poultry nutrition is limited by the presence of gossypol, a toxic polyphenolic pigment. Gossypol exists in CSM in two forms, free and bound. Free gossypol, as defined by AOCS official methods, are those gossypol and gossypol derivatives that are soluble in aqueous acetone and are physiologically active. Bound gossypol is insoluble in ether, chloroform or aqueous acetone and for the most part is physiologically inactive (Berardi & Goldblatt, 1980). The objectives of the experiments reported herein were to study of gossypol reduction by dehydrated ferro sulfate( DFS) and lecithin and also the feeding value of a commercially processed CSM in broiler diets.
