Abstract
An Afrikaner beef cow was presented for reproductive tract assessment. Records showed that the cow was last served by a bull during an oestrus two years earlier and appeared to be pregnant ever since. Failure to deliver this pregnancy led the farm management to request an investigation into why an animal with an impeccable calving history of five calves and was in good body condition was failing to deliver this particular ‘pregnancy’. Rectal examination revealed a soft rubbery structure on the right ovary, a doughy consistency in the uterus and a tight cervix whose lumen contained a structure which felt twig-like. Examination of the ovaries after slaughter confirmed small cysts on both ovaries, a large corpus luteum occupying almost 75% of the right ovary, pyometra and that the twig-like structure in the cervical lumen was an inspissated and crystalized mucous plug. These findings supported diagnosis of a persistent corpus luteum due to pyometra.
