administering to a ruminant a feed additive composition comprising about 1 wt. % to about 3 wt. % of a cobalt compound, about 0.5 wt. % to about 15 wt. % of one or more essential oils selected from the group consisting of thyme, cinnamon, and oregano, and about 48 wt. % to about 98 wt. % of a yeast component, wherein a ratio of the yeast component to the cobalt compound is between about 140:1 and 13:1, and wherein the feed additive composition contributes to at least one of: increased milk production of dairy cows, increased feed efficiency, increased digestibility, and an improvement in early rumen development, as compared to if the ruminant was not administered the feed additive composition.
