Serum samples of 181 selected sows had been taken the day before culling, reproductive tracts were examined and the culling reasons were recorded. In sows with histories of multiple returns cyclic ovaries were found predominantly. All of the few sows culled for prolonged behavioural oestruses suffered from ovarian cysts. 87% of the sows whose serum oestradiol level exceeded 10 pmol/l and whose serum progesterone level exceeded 2.5 pmol/l revealed ovarian cysts. In 72% of the sows whose hormone concentrations were below these levels inactive ovaries were found. Corpora lutea, partly in association with ovarian cysts were present in 91.1% of the sows whose sera exhibited progesterone levels greater than 2.5 nmol/l and concentrations of oestradiol less than 10 pmol/l. As a rule ovarian diagnoses by combined determination of oestradiol and progesterone could be confirmed by the results of morphological examination of the reproductive tracts. In practice after selection of sows suffering from fertility disorders an even better reliability in diagnosis of ovarian disorders may be achieved than in this investigation.
对181头选定的母猪在淘汰前一天采集血清样本，检查生殖道并记录淘汰原因。在有多返情史的母猪中，主要发现了周期性卵巢。因行为性发情期延长而淘汰的少数母猪均患有卵巢囊肿。血清雌二醇水平超过10 pmol/l且血清孕酮水平超过2.5 pmol/l的母猪中，87%存在卵巢囊肿。在激素浓度低于这些水平的母猪中，72%发现卵巢无活性。血清孕酮水平大于2.5 nmol/l且雌二醇浓度小于10 pmol/l的母猪中，91.1%存在黄体，部分与卵巢囊肿有关。通常，通过雌二醇和孕酮联合测定进行的卵巢诊断可以通过生殖道形态学检查结果得到证实。在实际操作中，在选择患有繁殖障碍的母猪后，卵巢疾病诊断的可靠性可能会比本研究中更高。
