Effect of Day Gestation on Induction of Lambing with Flumethasone¹

South Dakota State University, Brookings 57007

Abstract

Three-hundred and sixty-nine ewes were examined for the effect of day of flumethasone injection on induction of parturition. Ewes were treated with either 2 mg flumethasone (FLU) or physiological saline (control) on days 138 through 144 of gestation as determined by date of marking by rams. Average time to lambing post-treatment was 86.7 ± 8.0 hr for FLU-treated ewes and 155.9 ± 7.9 hr for control ewes (P<.01). Sixty-four percent of the FLU-injected ewes lambed within 72 hr after treatment, complied to 17% of the control ewes (P<.01). The average interval to lambing for the FLU-treated ewes responding within 72 hr was 49.5 ± 2.1 hours. FLU treatment on days 140 through 144 of gestation resulted in a shorter (P<.05) interval from treatment to birth and more (P<.01) ewes lambing within 72 hr after treatment than did treatment on days 138 and 139.
