Abstract

Retained placenta, common in postpartum dairy cows, involves those animals not releasing their placenta within 8-24 hours after parturition. Cows with retained placenta (RP) are more prone to metritis and cystic ovarian disease than healthy ones. On the other hand, metritis complex, in the presence and/or the absence of retained placenta, has a detrimental effect on reproductive performance. Although retained placenta can be minimized by application of preventive and control measures in the herd, removing the placenta by manual, hormonal, antibacterial and antiseptic ways are other suggested methods. The aim of the present study was to compare manual removal, conservative treatment and control (non-retained healthy cows) based on uterine bacteriological and cytological state and reproductive performance.
