Polyether ionophores--effect on rumen function in feedlot cattle

This article treated some of the modes of actions of ionophores in beef feedlot diets. It should be strongly emphasized that the predominant literature cited pertains to work with monensin sodium and more recently lasalocid sodium. There is ample evidence that the mode of action of these two ionophores is somewhat different and as new ionophores are cleared, it should not be assumed they follow the same mode of actions as described in this article.
