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-injected ewes and 155.9 +/- 7.9 hr for control ewes (P less than 0.1). Sixty-four percent of the FLU-injected ewes lambed within 72 hr after treatment, compared to 17% of the control ewes (P less than .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 less than .05) interval from treatment to birth and more (P less than .01) ewes lambing within 72 hr after treatment than did treatment on days 138 and 139.
对369只母羊进行了检查，以研究氟米松注射日对诱导分娩的影响。根据公羊标记日期确定，在妊娠第138天至144天，母羊分别接受2毫克氟米松（FLU）或生理盐水（对照）治疗。注射氟米松的母羊治疗后平均产羔时间为86.7±8.0小时，对照母羊为155.9±7.9小时（P<0.1）。64%注射氟米松的母羊在治疗后72小时内产羔，而对照母羊为17%（P<0.01）。在72小时内有反应的氟米松治疗母羊平均产羔间隔为49.5±2.1小时。与妊娠第138天和139天进行治疗相比，在妊娠第140天至144天进行氟米松治疗导致从治疗到出生的间隔更短（P<0.05），且更多（P<0.01）母羊在治疗后72小时内产羔。
