Blood characteristics of reindeer calves fed on lichens were studied during the winter. 2. The serum total protein, albumin and globulin concentrations decreased during the winter, obviously partly due to protein deficiency in the diet. 3. High urea levels in autumn and midwinter were possibly reflections of increased stress and/or protein catabolism. 4. Marked lipolysis occurred in late winter, and thus increases were observed in fatty acids, glycerol, triglycerides and acetoacetate concentrations. 5. Serum sorbitol dehydrogenase (SDH) activity increased towards the spring, most probably reflecting changes in the liver. 6. A decrease in serum alkaline phosphatase (AP) activity occurred in midwinter due to cessation of growth. 7. It can be concluded that all the animals were at least in moderate condition throughout the winter and the physiological responses to a negative energy balanced reflected good adaptation.

冬季对以地衣为食的驯鹿幼崽的血液特征进行了研究。2. 冬季血清总蛋白、白蛋白和球蛋白浓度下降，显然部分原因是饮食中蛋白质缺乏。3. 秋季和冬季中期尿素水平较高，可能反映了应激增加和/或蛋白质分解代谢。4. 冬末发生了明显的脂肪分解，因此脂肪酸、甘油、甘油三酯和乙酰乙酸浓度均有所增加。5. 血清山梨醇脱氢酶（SDH）活性在春季临近时升高，很可能反映了肝脏的变化。6. 由于生长停止，冬季中期血清碱性磷酸酶（AP）活性下降。7. 可以得出结论，所有动物在整个冬季至少处于中等状态，对负能量平衡的生理反应反映了良好的适应性。
