Methane emission traits heritable in cattle

Researchers in Australia have determined potential to use genetic selection to reduce methane emissions of beef cattle.

Researchers with the New South Wales Department of Primary Industries (DPI) in Australia have determined that methane emissions from beef cattle are a heritable trait.

The milestone research, published online in two articles in the Journal of Animal Science, offers the potential for using genetic selection to reduce greenhouse gas emissions from cattle without altering cattle performance.

Methane is a byproduct of microbial fermentation in the rumen. Methane emissio
