Environmental temperature and choline requirement in rats. I. Choline deficiency in rats at various temperatures.
Rats were maintained at 2 degrees, 21 degrees, and 33 degrees for 3 weeks on a choline-supplemented or a choline-deficient diet. In contrast to the findings of some other workers, choline deficiency produced fatty livers at all temperatures. The ratio of the total liver lipid to the total food intake was the same in all choline-supplemented rats. In choline-deficient rats this ratio was always higher and varied directly with temperature.
