Composition and method for reducing atmospheric methane and nitrous oxide emissions

摘要

The present invention provides compositions and methods for reducing atmospheric methane and/or nitrous oxide emissions using livestock feed additives and/or supplements. In a preferred embodiment, before the animal swallows feed and/or drinking water, a composition comprising beneficial microorganisms and/or their growth by-products is contacted with them. The composition, for example, can control methanogenic microorganisms in the digestive system of the animal, thereby reducing the content of intestinal methane emissions produced from animals and animal waste.
