Metagenomic approach to assist genetic improvement programs in reducing methane emissions and improving feed efficiency from beef cattle. [Abstract]
Beef meat is one of the products with the highest intensity of greenhouse gas emissions in livestock production chains. Emissions are mainly in the form of methane (CH4) produced by enteric fermentation. This process is carried out by the symbiotic ruminal microbiota and causes a loss of energy for the host which may decrease the feed efficiency (FE).
