During an abattoir survey, 8071 bovine genitalia were examined. Cysts of 2-5 cm or larger were found on one or both ovaries in 307, an incidence of 38 per cent. The cysts were arbitrarily classified anatomically into eight groups according to the number present and their texture, whether thin or thick walled, and to the presence or absence of a corpus luteum. The weight and dimensions of the cysts were recorded and any abnormalities of the genital tracts were noted. Ninety-six specimens (30-67 per cent) were associated with a corpus luteum and 217 (69-33 per cent) had no corpus luteum. One hundred and sixty eight tracts (53-67 per cent) had single cysts and in 145 (46-33 per cent) they were multiple. The incidence of multiple ovulations was higher in the cystic ovaries which had corpora lutea than in the non-cystic population. The incidence of ovaro-bursal adhesions in the cystic population was three times higher than in that found in the genitalia which had no cysts and it is possible that this resulted from trauma during rectal palpation.
在一次屠宰场调查中，检查了8071个牛的生殖器。在307个样本中，一个或两个卵巢上发现了2至5厘米或更大的囊肿，发生率为38%。根据囊肿的数量、质地（薄壁或厚壁）以及是否存在黄体，将囊肿任意地解剖学分类为八组。记录了囊肿的重量和尺寸，并注意到生殖道的任何异常情况。96个样本（30.67%）与黄体有关，217个（69.33%）没有黄体。168个生殖道（53.67%）有单个囊肿，145个（46.33%）有多个囊肿。有黄体的囊性卵巢中多排卵的发生率高于非囊性群体。囊性群体中卵巢与囊袋粘连的发生率比无囊肿的生殖器中发现的发生率高3倍，这可能是直肠触诊时的创伤所致。
