Ewes were unilaterally ovariectomized and/or hypophysectomized and treated with PMSG and hCG. For a given gonadotrophin treatment the ovulation rate per ewe was maintained, i.e. the ovulation rate of the remaining ovary was significantly increased (P less than 0.05), after the removal of one ovary in hypophysectomized and in pituitary-intact ewes. It is concluded that compensation of ovulation rate in the remaining ovary after unilateral ovariectomy in the sheep may be independent of feedback from the ovary and the release of gonadotrophins from the pituitary gland.
对母羊进行单侧卵巢切除和/或垂体切除，并使用孕马血清促性腺激素（PMSG）和人绒毛膜促性腺激素（hCG）进行处理。对于给定的促性腺激素处理，在垂体切除的母羊和垂体完整的母羊中，切除一侧卵巢后，每只母羊的排卵率得以维持，即剩余卵巢的排卵率显著增加（P<0.05）。得出的结论是，绵羊单侧卵巢切除后，剩余卵巢排卵率的代偿可能与卵巢反馈及垂体释放促性腺激素无关。
