Method and composition for controlling rumen release of cobalt to rumen bacteria to produce vitamin B12

摘要

Compositions and methods that are a unique source of cobalt for improved production of vitamin B _{12 in} the rumen. This has the advantage of a slow release source of cobalt combined with a rapid release source of cobalt. Rapid cobalt ion release sources, which are soluble sources of cobalt, take over more rapidly in the rumen than insoluble cobalt sources are taken over.
