COMPARISON BETWEEN IRRADIATION OF DIET AND SUPPLEMENTAL IRRADIATION OF ANIMALS IN VITAMIN A AND D DEFICIENCY.
The stimulating effects of the Vitamin D thus supplied became quite apparent and lasted for 10 days, then began to subside. The animals in Lot 2 were allowed to exist on the Sherman No. 380 diet, with supplemental Vitamin D, in the form of irradiated ergosterol, but in Lot 1 the animals were also irrradiated daily except Sundays, for 30 seconds, at a distance of 18 inches from a Macbeth carbon arc lamp.
