Cobalt Toxicity in Calves Resulting from High Oral Administration

Abstract

Equivalent amounts of cobalt fed as the sulfate, chloride or carbonate were equally toxic to the dairy calf. Cobalt fed in excess of 40 mg. daily per 100 pounds of body weight produced toxic effects in dairy calves. Increasing the methionine content of the grain ration by addition of casein did not reduce the toxicity of cobalt fed to dairy calves.
