CHOLINE has been shown by Jukes (1940, 1941) to prevent perosis and promote growth in turkeys and chicks. Soybean oil meal was observed to have perosis-preventing and growth-promoting properties. These were ascribed at least in part to the choline content of the meal. Confirmatory evidence of the role of choline in preventing perosis and promoting growth in chicks has been reported by Hegsted and others (1941) and Record and Bethke (1942). Methionine was shown by Jukes (1941) to have no growth-promoting or perosis-preventing properties when added to a basal ration containing 30 percent casein. This suggested that methionine does not act as a precursor of choline for the chick. Conversely, it has been demonstrated by Griffith and Wade (1939) that methionine may act as a precursor of choline for the rat. On the other hand, choline has been reported by Klose and Almquist (1941) to act as a precursor of . . . |
