Studies on the Vitamin B1 Requirements Of Growing Rats

Abstract
The autoclaved grain ration (ration 240A) cannot be used for studies on vitamin B1 with rats unless it is considerably modified. A synthetic vitamin B1 low ration (ration 112) has been developed which includes several recently disclosed factors of the vitamin B complex. Rats restricted to ration 112 supplemented with 80 to 100 micrograms of vitamin B1 hydrochloride per 100 gm. of ration grow at a normal rate.
