Abstract

KUMMEROW, Weaver and Honstead (1949) found that the addition of high levels of fat to the diet increased the requirement of the chick for choline. Siedler and Schweigert (1953), on the other hand, observed no gain from choline supplementation of diets containing from 2 to 8 percent of added fat. Frazer (1946) and Tidwell (1950) reported that choline accelerated absorption of fat in the rat. The data in the literature indicate that choline requirement is not always raised by increasing the dietary fat level; nevertheless, there is often an effect in this direction. Because of the recognized interrelationship among choline, folacin, vitamin B12 and methionine, it seemed possible that contradictory evidence regarding the effect of dietary fat on choline requirement may be the result of differences in the composition of the experimental diets.Schaefer, Salmon, Strength and Copeland (1950) and Strength, Schaefer and Salmon (1951) demonstrated an interrelationship between the …
