摘要

Methane is 21 times more potent than CO_2 as a greenhouse gas (GHG), and dairy cows typically produce 118 kg methane/year, which is over twice that produced by other non-lactating cattle. Evaluation of strategies to reduce methane production should consider the effects on total farm greenhouse gas emissions. Increasing productivity per cow will reduce methane emissions per kg of milk and total farm GHG emissions where milk production is fixed, although the effect on total farm emissions needs further clarification. A lower culling rate will reduce farm methane and total GHG emissions.
