Abstract
Two experiments are reported in which no evidence of nicotinicacid deficiency could be noted in growing pigs receiving dietscontaining 80 and 84 percent of corn respectively and supplyingat least 0.7 and 0.8 mg. of nicotinic acid respectively perkilogram live weight per day.
A third experiment is reportedin which severe nicotinic aciddeficiency resulted from feedingdiets containing 40 and 70percent of corn combined with purifiedmaterials, and supplying0.36 and 0.47 mg. of nicotinic acidrespectively per kilogramlive weight per day.
Evidence ofa pellagragenic effect of corn was obtained whichappeared tobe not necessarily an anti-nicotinic acid effect.
