Forage quality, a central focus for all nutritional approaches in dairy cows, can play a role in CH4 mitigation.

Not only from an environmental standpoint, but also to improve rumen function and performance of the cow, it is important to mitigate methane production. Improved feed efficiency, achieved through feeding good quality forage, can contribute to reductions in CH4 production per kg of milk. Maturity at harvest is a key factor to consider with younger forage material generally yielding greater quality. Good ensiling and storage are essential to produce quality forage, maximise the conservation of nutrients and improve efficiency of production.
