在冬眠早期，蝙蝠的血糖随体温的升高而升高。在冬眠后期，血糖水平随温度升高而升高，但速率较慢。糖原被证明是一个贫穷的能源所需的冬眠过程中。蝙蝠在冬眠期间利用的糖原和脂质储存分别足以维持动物12小时和11周，这表明其他能量储备的增加。通过对血尿素氮浓度的研究，提出了冬眠蝙蝠对蛋白质的利用。去冬眠动物的呼吸系统反应表明，除脂类以外的物质在醒来后被分解代谢，糖原的少量储存表明蛋白质是代谢混合物的一种成分。
Early in the period of hibernation, the blood glucose of the bat was found to increase logarithmically with body temperature during dehibernation. Late in the period of hibernation, the blood glucose level increased with temperature but at a slower rate. Glycogen was shown to be a poor source of the energy required during dehibernation. The glycogen and lipid stores utilized by the bat during its hibernating period are sufficient to maintain the animal for 12 hours and 11 weeks, respectively, indicating the catabolism of other energy reserves. The utilization of protein in the hibernating bat is suggested by studies on blood urea nitrogen concentrations. Respiratory quotients of dehibernated animals indicate that materials other than lipids are catabolized after awakening, and the small stores of glycogen suggest protein as a component of the metabolic mixture.
