Endometritis is a significant condition in postpartum dairy cattle because it causes infertility.1 Although pathogenic bacteria underlie the aetiology of clinical endometritis (Box 1), peripartum problems such as dystocia and retained placenta increase the risk of disease. Metabolic stress is another risk factor for clinical endometritis2,3 and a recent study by Valdmann and others, summarised on p 126 of this week’s issue of Vet Record,4 extends this observation to include cytological endometritis. This finding is important because metabolic stress is a common feature of intensive dairy farming, and metabolic demands on cows will rise further because milk yields are expected to double in the next 50 years.5
