In 8 experimental ewes on normal diet the influence of pregnancy and feeding on insulin and glucose in the blood was studied. A reduction in insulin concentration was found as pregnancy advanced. Blood glucose fluctuated, but during late pregnancy the blood glucose level was significantly lower in twin–pregnant ewes than in ewes pregnant with 1 fetus. No increase in insulin concentration was demonstrated in twin–pregnant ewes after feeding, on the contrary an increase was found in ewes pregnant with 1 fetus. A limited effect of feeding on the glucose concentration was observed, especially compared to the reference range. A positive correlation was obtained between the concentration of glucose and insulin in the blood.
在8只正常饮食的实验母羊中，研究了怀孕和喂养对血液中胰岛素和葡萄糖的影响。随着怀孕进程的推进，胰岛素浓度降低。血糖有波动，但在怀孕后期，怀有双胞胎的母羊的血糖水平显著低于怀有单胎的母羊。怀有双胞胎的母羊进食后胰岛素浓度没有增加，相反，怀有单胎的母羊胰岛素浓度增加。观察到进食对葡萄糖浓度的影响有限，尤其是与参考范围相比。血液中葡萄糖浓度和胰岛素浓度之间呈正相关。
