Induction of parturition in the ewe.
One-hundred and seventeen ewes were used in a study of induction of parturition. Ewes were treated with either 2 mg flumethasone (FLU), 15 mg prostaglandin F2 alpha-THAM salt (PGF) or physiological saline (control) on day 141 of gestation, as determined by dates of marking by rams. Eighty-nine percent of the ewes treated with FLU and 33% of the ewes treated with PGF lambed within 72 hr post-treatment. More (P less than .01) ewes treated with PGF or FLU lambed within 72 hr than did control ewes. The interval from treatment to parturition was shorter in FLU (P less than .01) and PGF (P less than .05) treated ewes than in ewes given saline.
