Abstract

To investigate the effect of dinoprost to the exclusion of the purulent exudate, the change of intrauterine bacteria and the reproductive performance in cows with pyometra, 13 Holstein cows with pyometra were treated with tromethamine dinoprost intramuscularly (25 mg as dinoprost) one time on the day when pyometra was diagnosed. Then intrauterine perfusion fluid was collected for bacteriological examination at 3 days and 21 days after dinoprost treatment. In all cows estrus was induced by the dinoprost treatment within four days and the purulent material in the uterus was excreted from the uterus. Although Trueperella pyogenes was isolated in 12 cows out of 13 cows at the first bacteriological examination, it was isolated in only two cows at the second bacteriological examination. Seven out of 10 cows which received artificial insemination became pregnant after the dinoprost treatment. In conclusion, the dinoprost treatment is effective to not only exclude the purulent exudate but also eliminate T. pyogenes from uterus.
