The existence of significant and sufficient genetic variation in fertility is generally accepted and most leading dairy cattle breeding programmes have included fertility in their selection indices (Miglior and others 2005). This multi-trait selectio

In-line milk progesterone records (n = 163,145) collected from June 2009 through November 2013 for 2,274 lactations of Holstein-Friesian cows in 12 commercial herds in the Netherlands were analyzed for commencement of luteal activity (CLA), luteal ac
