The objective of this trial was to evaluate the impact of a control program based on systematic clinical examination on day 10+/-3 postpartum (pp) and treatment in the case of puerperal metritis on reproductive performance in dairy cows. Cows having serious dystocia as well as cows treated for retained placenta were not involved in the trial. The evaluation was performed by comparing reproductive performance between systematically examined cows (group E, n=83) and cows that were examined and treated occasionally on the basis of farmers' notifications of a pathological condition (group C, n=95). In group E, reproductive performance was compared between cows with a mild form of metritis (group E1, n=18), cows with a severe form of metritis (group E2, n=14) and cows without puerperal metritis (group E0, n=51). Clinical examination consisted in rectal and vaginal palpation with inspection of the lochia manually withdrawn from the vagina. Cows with puerperal metritis were treated with an intramuscular administration of PGF2alpha analogue - dinoprost. An intrauterine antibiotic (rifaximin foam) was added in cases of severe metritis. The examination and treatment (in cases of a pathological condition, n=10) were repeated in group E on day 24+/-3 pp. Occurrence of ovarian disorders and clinical endometritis, calving to first service interval, pregnancy until day 100 pp as well as until day 150 pp, services per conception, calving to conception interval, total culling rate and culling rate due to (sub)infertility in group E compared to group C were not different. Only the first service pregnancy rate was lower in group E (30.3 vs. 47.1%, P less than 0.05). The worst results (non-significant) were in group E2. There was no beneficial effect either of systematic clinical examination on day 10+/-3 pp or of the treatment of puerperal metritis on reproductive performance in dairy cows.
