Treatment of Postpartum Metritis In Dairy Cows Caused by Actinomyces Pyogenes

Abstract

Three treatments (oxytetracycline infusions, prostaglandin injections, and no treatment) were applied to Holstein cows with postpartum metritis from which A pyogenes had been isolated from the uterus. Gross involution was not different between groups, but oxytetracycline infusions significantly reduced (P <0. 005) the incidence of A pyogenes infected uteri. Numbers were too small to pass judgement on fertility between groups, but when all groups were combined fertility was definitely reduced.
