Vitamin B₁₂ and Cobalt Concentrations in Livers from Healthy and Cobalt-deficient Lambs

Abstract

DURING field investigations into cobalt deficiency we collected pasture samples from experimental paddocks at intervals for cobalt analyses, and at the end of the trials made comparisons of the vitamin B₁₂ and cobalt concentrations in the livers of healthy lambs not given cobalt, cobalt-dosed lambs, and other groups showing various stages of cobalt-deficiency disease. Results are shown in Table 1.
