Cottonseed Meal as a Substitute for Soybean Oil Meal in Poultry Rations ,

Abstract

RINGROSE and Morgan (1938) reported that hydraulic cottonseed meal could replace one-half of the meat scraps in chick starter rations. Boatner et al. (1948) showed that chick growth was retarded by gossypol and related substances in cottonseed meal. Clark et al. (1948) found solvent cottonseed meal to be slightly superior to hydraulic cottonseed meal when fed to chicks. They also reported that equal parts of solvent or hydraulic cottonseed meal with soybean oil meal gave results similar to that obtained with soybean oil meal alone. Lillie and Bird (1950) concluded from their studies that the toxicity of cottonseed pigment glands fed to chicks daily by capsule was due entirely to the gossypol content of the glands. Richardson and Blaylock (1950a) obtained rapid growth in young chickens fed a diet which contained cottonseed meal as the only source of protein, when the diet was supplemented with vitamin B12 and synthetic lysine …
