Ovarian removal has been indicated for cases showing pain associated with grossly enlarged ovaries due to cysts, haematoma and abscesses. In female donkeys presenting with signs of abdominal pain, a rectal examination is indicated to assess the condition of the ovaries. Ultrasound per rectum and via the flank is required to fully evaluate the ovary. We have encountered

ovaries up to 20 cm in diameter due to abnormalities. In some cases external flank drainage of the ovary may be useful to temporarily alleviate the discomfort. We use two operators for this procedure, one with the arm per rectum to stabilize the ovary against the abdominal wall and one to aspirate the cyst externally.
