Berry et al. (1943 a, b) and Marvel et al. (1944, 1945 a, b) have emphasized the supplementary value of 0.15 percent of synthetic choline chloride in chick diets consisting of yellow corn, soybean oil meal, alfalfa leaf meal, and mineral and vitamin supplements. The diets included whey solubles in some cases and distillers’ dried solubles in others. Marvel et al. (1944) stated that “choline and methionine exerted an interchangeable supplementary action” on such diets. Bird and Mattingly (1945) found that dl-methionine, but not choline chloride, effectively promoted the growth of chicks fed a diet of grains, millfeeds, soybean oil meal, alfalfa meal, and mineral and vitamin supplements. The differences in the diets used afforded no obvious explanation of the difference in findings with respect to choline chloride. However, it was noted that in the studies of this compound reported by Berry et al., and Marvel et al., unusually high . . .
