A comparison was made of alcohol-extracted casein and heat-treated casein as a source of protein in the vitamin A-free basal diet of carefully matched experimental rats.
No marked differences were observed in the growth responses, time for depletion or survival period of groups of animals on the two diets, with and without added vitamin A supplement.
