title: Prevalence of postservice pyometra in a herd of beef cows infected with trichomoniasis: A case report.
abstract: Trichomoniasis was detected in a herd of beef cows during a routine yearly reproductive examination. The examination revealed that 12.6% of the cows (75 597 ) were not pregnant. Of these, 65.3% (49 75 ) had a normal uterus and a functional corpus luteum, suggesting that they were cyclic; 21.3% (16 75 ) had pyometra; 6.7% had inactive ovaries and uterine atrophy and were not cyclic; 4% (3 75 ) had an involuting uterus, suggestive of a recent abortion; and 2.7% (2 75 ) had a mummified fetus. The herd had been on a reproductive herd health program for the past 10 years and had averaged 92-99% pregnant cows during this time. Pyometra was diagnosed by rectal palpation, and trichomonads were detected in the pyometra exudate.
