Experiments with pigs on a pellagra-producing diet. II

Abstract

Pigs fed on a pellagra producing diet consisting chiefly of maize sickened and died unless the diet was changed. The nutrient in autoclaved yeast extract which rendered the diet wholesome for pigs was adsorbed by fuller''s earth at pH 1.3. Expts. on the curative action of nicotinic acid previously reported were extended. Riboflavin was without effect in preventing or curing the symptoms developed on the maize diet. Pigs which ate wheat straw, in addition to the basal diet, throve. Rats grew well and even reproduced on the maize diet on which pigs died.
