【 摘 要 】

References(12)Cited-By(2)Of 170 cows with ovarian cysts which were detected by palpation of the ovaries per rectum, 88 cows (51.8%) were diagnosed as having follicular cysts on the basis of milk progesterone concentrations. Eighty-three of the 88 cows were used for treatment trials. A group of 56 cows injected subcutaneously with fenprostalene, prostaglandin F2α analog, 14 days after treatment with fertirelin, an analog of gonadotropin-releasing hormone, compared with another 27 cows treated only with fertirelin (controls), showed a higher pregnancy rate within 100 days after the initial treatment (66.1 vs 48.1%) and shorter intervals from the treatment to conception (30±21 vs 43±27 days). It was concluded that the administration of fenprostalene following fertirelin treatment is effective in shortening the interval from treatment to conception in cows with follicular cysts.
