The opportunity to breed more climate-friendly cows is one step closer for New Zealand dairy farmers after a Waikato trial finds a possible link between a bulls’ genetics and the amount of methane they produce.

CRV introduced the feed efficiency breeding value in December. Willem Alders has been conducting feed trials for CRV for several years. He sees huge differences, also between similar cows.
