Abstract
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 < 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.
