Abstract
Description
The article is concerning the importance of cobalt to the diets of swine. The trace mineral, cobalt, proved to be a valuable addition to the rations of cattle and sheep where this mineral appeared to be lacking. Cobalt must be present if the rumen micro-organisms are to function normally. Cobalt needed to be fed and not injected for the best results. It was thought that swine could not utilize elemental cobalt. An experiment demonstrating this misconception was made at the North Dakota Experiment Station. Small additions of cobalt to the diets of swine increased their rate of gains.
