Abstract

Bénédicte Suybeng investigated the effect of supplementing tropical beef cattle with Desmanthus on in vivo methane emissions and performance. She found that Desmanthus can maintain animal liveweight, health status and improve nitrogen utilisation without negatively affecting rumen fermentation and plasma metabolite profiles. However, on high-quality diets, Desmanthus did not reduce methane emissions. Meat & Livestock Australia is using the results of her study.
