Last month we evaluated data indicating that only 35% of current methane emissions from domestic ruminants is contributing to increased atmospheric methane. With reductions in methane emissions ranging from 10 to 50%, feed additives could almost eliminate the 35% contributing to atmospheric methane.  Many feed additives have potential adverse effects on the animal, but 3-nitrooxyproponal reduces methane emissions without negatively affecting animal performance and is in the process of commercialization. Furthermore, 3-nitrooxypropanol shifts rumen VFA profile toward higher proportions of propionate making the ruminant animal more feed efficient and the compound very attractive to economically include in livestock rations.
