| abstract |
The subject invention provides compositions and methods for reducing atmospheric methane and/or nitrous oxide emissions using livestock feed additives and/or supplements. In preferred embodiments, a composition comprising a beneficial microorganism and/or a growth by-product thereof is contacted with animal feed and/or drinking water prior to the animal ingesting it. The composition is capable of, for example, controlling methanogenic microorganisms within the animal's digestive system, and thus, reducing the amount of enteric methane emissions produced from the animal and from the animal's waste. |
