Weekly reproductive health examinations were performed on 46 multiparous Holstein cows from 14 to 100 d post partum. Sixteen cows developed 19 nonsimultaneous ovarian cysts, with a mean day of first detection at 34.3 +/- 4.5 d post partum and a mean duration of 31.0 +/- 4.3 d after first detection. Coccygeal blood was collected three times weekly, and plasma progesterone concentrations were determined by radioimmunoassay. Cysts were diagnosed by palpation per rectum or by ultrasonography and classified as follicular or luteal cysts; the cows were not treated. Cows with a mean plasma progesterone concentration of < 1 ng/ml from the first day of detection (Day 1) of a cyst until Day 10 were classified as having a follicular cyst, and those with a mean plasma progesterone concentration of >or= 1 ng/ml from Day 1 to Day 10 were classified as having a luteal cyst. According to this classification, 58% of the cysts were follicular and 42% were luteal. There was an overall 47% agreement between classification by palpation and by ultrasonography on Day 1 with progesterone concentration during Days 1 to 10 after detection of the cyst. Detailed graphs of progesterone concentrations and area of largest follicles or cysts and corpora lutea demonstrate the variability of ovarian structures and progesterone profiles in cystic cows. Detection of a cyst at any one time accompanied by simultaneous measurement of progesterone can lead to different diagnoses of cyst type depending on the method of classification, the presence and age of luteinized tissue in the cyst and undetected corpora lutea.
对46头经产荷斯坦奶牛在产后14至100天进行每周一次的生殖健康检查。16头奶牛出现了19个非同时发生的卵巢囊肿，首次检测的平均天数为产后34.3±4.5天，首次检测后平均持续时间为31.0±4.3天。每周采集三次尾静脉血，采用放射免疫分析法测定血浆孕酮浓度。通过直肠触诊或超声检查诊断囊肿，并将其分为卵泡囊肿或黄体囊肿；这些奶牛未接受治疗。从囊肿检测第一天（第1天）到第10天，平均血浆孕酮浓度<1 ng/ml的奶牛被分类为卵泡囊肿，而从第1天到第10天平均血浆孕酮浓度≥1 ng/ml的奶牛被分类为黄体囊肿。根据这一分类，58%的囊肿为卵泡囊肿，42%为黄体囊肿。在囊肿检测后第1天，通过触诊和超声检查进行的分类与第1至10天孕酮浓度之间的总体一致性为47%。孕酮浓度以及最大卵泡或囊肿和黄体面积的详细图表显示了患囊肿奶牛卵巢结构和孕酮水平的变异性。在任何时候检测到囊肿并同时测量孕酮，根据分类方法、囊肿中黄体化组织的存在和年龄以及未检测到的黄体情况，可能会导致对囊肿类型的不同诊断。
