As methane emission of dairy cows is the main component of this carbon footprint, and the Dutch agriculture is facing the challenge to reduce the methane emissions with 2.1 Mton by 2030, and even further by 2050, farmers urgently need efficient and cost-effective options to reduce methane emissions. Selective breeding as an additional mitigation strategy is cost-effective, permanent, and cumulative, and can also easily be included in the day-to-day herd management at low direct costs.
