The ability of 8 pregnant ewes to maintain glucose homeostasis following an intravenous glucose load (glucose tolerance test) and during starvation in late pregnancy was studied. Following an intravenous load 2 out of 7 ewes tested showed an impaired insulin secretion during the first 10–15 min. An increase in plasma insulin concentration was found 50–60 min after the injection. The results of the effect of a starvation on a number of blood constituents are demonstrated. Two of the twin–pregnant ewes developed symptoms of pregnancy disease following starvation, these were the same ewes that showed an impaired insulin secretion after the glucose load. However, no difference was demonstrated in the clinical chemical parameters whether the experimental ewes developed pregnancy disease or not.
研究了8只怀孕母羊在静脉注射葡萄糖负荷（葡萄糖耐量试验）后以及妊娠晚期饥饿期间维持葡萄糖稳态的能力。在静脉注射负荷后，7只接受测试的母羊中有2只在最初10 - 15分钟内胰岛素分泌受损。注射后50 - 60分钟发现血浆胰岛素浓度升高。展示了饥饿对多种血液成分影响的结果。两只怀有双胞胎的母羊在饥饿后出现了妊娠疾病症状，这两只母羊就是在葡萄糖负荷后胰岛素分泌受损的那两只。然而，无论实验母羊是否出现妊娠疾病，临床化学参数均未显示出差异。
