Abstract

Methods and compositions are provided for method of enhancing feed utilization efficiency in a ruminant animal by adding to the feed a sufficient amount of a nonionic surfactant to enhance the utilization of the feed by the animal. The methods and compositions result in enhanced weight gain and/or milk production by the animal. Preferred nonionic surfactants include polyoxyethylenesorbitan monooleate and polyoxyethylenesorbitan trioleate at a concentration range of from about 0.01 to 1% (w/w) of the dry weight of the feed.
