Four Finnish Landrace X Dorset Horn ewes were each given an intramuscular injection of 15 mg of dexamethazone on day 142 of gestation. Four ewes with the same fetal numbers were used as controls. Administration of the corticosteroid reduced the mean gestation length from 146-5 to 143-3 days and had no effect on the pre-lambing concentrations of Na, Cl, Ca P and Mg in the maternal plasma or on blood pH. There was a slight but significant (P less than 0-05) decrease in plasma K before lambing in the treated ewes. Plasma urea and glucose concentrations were not affected by treatment. There was a significant increase in the plasma concentration of glucose in both groups of ewes immediately after parturition.
4只芬兰长白×多塞特角杂交母羊在妊娠第142天分别肌肉注射15毫克地塞米松。选取4只怀有相同数量胎儿的母羊作为对照。注射皮质类固醇使平均妊娠期从146.5天缩短至143.3天，对母羊血浆中产前钠、氯、钙、磷和镁的浓度以及血液pH值均无影响。处理组母羊产羔前血浆钾略有下降，但差异显著（P<0.05）。血浆尿素和葡萄糖浓度不受处理影响。两组母羊产后即刻血浆葡萄糖浓度均显著升高。
