Reductions in emissions could be achieved by selecting for reduced dry matter intake, while maintaining production. Genomic breeding values for methane emission levels, can allow farmers to select dairy cattle with reduced methane emissions.

What Can I Do?

Since the level and type of methane-producing microbes in a cow is largely influenced by the cow’s genetic makeup, cattle could be selected based on this trait. This approach is more permanent than changing the cattle’s diet.
