A Comparison of Soybean Oils and Soybean Oil Meals in Chick Rations Containing Distillers’ Dried Solubles ,

Abstract

SYNOLD (1942) has reported a choline deficiency in a corn and soybean oil meal ration containing distillers’ dried solubles as a vitamin supplement. It was suggested that the method of processing might affect the choline content or availability. Choline had previously been shown by Jukes (1940, 1941) to be an anti-perotic and growth-promoting factor for chicks. Berry and associates (1943a) reported choline to be a limiting factor in chick rations containing approximately one-third soybean oil meal, but containing no animal protein supplements. Later Berry and associates (1943b) conducted experiments comparing soybean oils and oil meals produced by expeller and solvent processes. However, the rations used were different from the original rations of Synnold (1942) in that whey solubles was used as a vitamin supplement instead of distillers’ solubles. Therefore, additional experiments were conducted in which the vitamin supplement was distillers’ dried solubles, and the experiments were extended to include a .
