摘　　要：为了研究不同能量水平日粮对兰州大尾羊、小尾寒羊、藏羊、小尾寒羊及德国美利奴高代杂种羊血液生理生化指标的影响。试验选发育正常、年龄、体重基本一致的兰州大尾羊、小尾寒羊、藏羊、小尾寒羊及德国美利奴高代杂种羊各30只,每个绵羊类群随机分为3组,每组10只,采用全自动生化分析仪测定了血液中葡萄糖(GLU)、总蛋白(TP)、白蛋白(ALB)、球蛋白(GLO)、甘油三脂(TG)、总胆固醇(CHO)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)的含量。结果表明:同一类群绵羊血液中的TP、ALB、GLO含量随着日粮能量水平的增加而降低;而对于各类群绵羊血液中的TG、CHO含量而言,高能量水平日粮条件下显著高于中能量水平与低能量水平日粮(P<0.05);在同一能量水平日粮条件下,小尾寒羊与藏羊血液中的GLU含量显著(P<0.05)或极显著(P<0.01)低于兰州大尾羊与德国美利奴高代杂种羊,兰州大尾羊和小尾寒羊血液中的TP、ALB、GLO含量显著(P<0.05)或者极显著(P<0.01)高于藏羊和德国美利奴高代杂种羊。For studying the effects of different energy rations on blood physiological and biochemical indexes of Lanzhou Fat-Tailed Sheep, Small-Tailed Han sheep, Tibetan sheep and high hybrid German Merino. 120 sheep （Lanzhou Fat-Tailed sheep （n=30）, Small-Tailed Han sheep （n=30）, Tibet sheep （n=30） and high hybrid German Merino （n=30）） within well-developed, same age and weight were selected in the study, respectively. Every group was divided equally into three subgroups randomly and each subgroup had 10. The contents of blood glucose（GLU）, total protein（TP）, albumin（ALB）, globulin（GLO）, triglyceride（TG）, total cholesterol（CHO）, high-density lipoprotein（HDL） and low-density lipoprotein（LDL） were determined by Automatic Chemistry Analyzer. The results showed that： With the increasing levels of dietary energy, the contents of TP, ALB, GLO were reduced in the same groups, however, the percent of TG and total CHO of blood under high energy ration was significantly higher than intermediate and low energy ration （P〈0.05）, at the same energy ration, the GLU percent in the blood of Small-Tailed Han sheep and Tibetan sheep was significantly （P〈0.05） or very significantly （P〈0.01） lower than Lanzhou Fat-Tailed sheep and high hybrid German Merino. The contents of total （TP）, （ALB） and （GLO） in the blood of Lanzhou Fat-Tailed sheep and Small-Tailed Han sheep was significantly （P〈0.05） or very significantly （P〈0.01） higher than Tibetan Sheep and high hybrid Germany Merino.
