title: [Ovarian cysts in cattle--etiology, therapy success, fertility].
abstract: The functions of the ovaries were controlled in 92 cattle over a period of 12 to 95 days p.p. Cystic follicles developed in 61% (25 from 41) during reconvalescence period and were correlated with a 4.2 days earlier onset of ovarian function, which was assured statistically. All together in 41 animals cystic degeneration was registered. Cysts having appeared before day 39 p.p. receded spontaneously in 24%, those having developed later remained. By application of the GnRH-analogous Buserelin (Receptal), either exclusive or combined with beta-carotene or Prostaglandin Trometamol-Tiaprost (Iliren) ovarian function could be restored in all cases. Restitution was most rapid when using Buserelin plus beta-carotene (Fertilizing insemination 3 weeks post application), but protracted after the consecutive method of therapy. All 92 cattle became pregnant. The P4-level of all "cyst-cows" were low, i.e. between 0.68 and 0.81 ng/ml of skimmed milk. The increase of conductivity of the cervical mucus to above 30 Ohm turned out an evidence of an ovarian cyst to be present. Restoration took longer in correlation with the increasing diameter of the cysts.
