Abstract
PREVIOUS studies (Kummerow et al., 1948 and Hite et al., 1949) have indicated that the skin fat of turkeys which had been fed either ethanolamine or choline was more stable than the fat from unsupplemented birds. Ethanolamine, therefore, seemed to be functional in the metabolism of fat in poultry although it has been reported to be nonfunctional in growth and the prevention of perosis. Jukes (1941) found that ethanolamine could not replace choline when fed to chicks which were kept on a purified ration. On the other hand, McGinnis, Norris and Heuser (1944) found betaine and methoinine prevented perosis on a simplified ration, but not on a purified ration similar to the one used by Jukes.In the present study the choline replacement value of ethanolamine was tested with chickens kept on a ration which contained 25 percent linseed oil. The latter was added to the ration, as Sharpless (1940) .
