    Abstract / Zusammenfassung

    Two methods for a scheduled postpartum examination were compared on a commercial dairy farm. The effects of the intensity of these methods on the reproductive performance of dairy cows were investigated. In Group 1, all cows (n=601) were examined by rectal palpation between days 20 and 26 postpartum for signs of endometritis (vaginal discharge, enlarged uterus). In Group 2, all cows (n=652) were examined by external adspection for vaginal discharge as a sign for endometritis. In both groups, all cows with endometritis were treated twice with prostaglandin F2alpha (25 mg of dinoprost) in a 14-day interval. The proportion of cows with signs of endometritis was 33.3 and 17.2% in Groups 1 and 2, respectively (P < 0.05). In Group 1, the conception rate (39.0 vs. 49.3%) and the proportion of pregnant cows (60.5 vs. 72.6%) were lower for cows with endometritis than for cows without endometritis. In Group 2, no significant differences were found in reproductive performance for cows with and without signs of endometritis. No significant differences in reproductive performance were found for cows with endometritis between the 2 groups. For cows without endometritis, no significant differences in reproductive performance were found between the groups. It is concluded that the postpartum examination by rectal palpation was more sensitive in finding cows with endometritis. However, with regard to the reproductive performance, the more sensitive method was not that effective compared to the method based on systematic external adspection
