Studies on the Concentration of Some B-Vitamins in the Blood of Normal and Cobalt Deficient Sheep

Abstract

The concentrations of nicotinic acid and vitamin B₆ group in the blood of cobalt deficient sheep were found to be lower than those in the normal animals; there was a suggestion of a similar lowering in the case of riboflavin. The folic acid and pantothenic acid contents were not affected. The relation of cobalt metabolism in ruminants to endogenous production of certain of the B-vitamins is discussed.
