Teagasc has bought Danish Jerseys to establish a new elite purebred Jersey herd in Moorepark. Fifty-eight purebred Jersey maiden heifers arrived into Ireland this week.Denmark, Sweden and Finland all share a common breeding index called the Nordic Total Merit index (NTM). This index is similar to the EBI in that it analyses multiple traits and is based on economic values for each trait. Therefore, production and health traits constitute a large part of the NTM index. The aim of the index is to produce long-living and high-producing cows.
