摘　　要：分别于冷、暖2季,采用黄嘌呤氧化酶法测定高原型藏系绵羊血浆铜锌超氧化物歧化酶的活性,用火焰原子光谱法测定血浆铜含量,以及对血浆铜含量与铜锌超氧化物歧化酶的活性进行相关分析。结果表明,冷、暖2季血浆铜锌超氧化物歧化酶的活性分别平均为169.867 2,278.612 8 U/mL,血浆铜含量相应分别平均为1.863 0,2.105 2μg/g,二者均为暖季极显著高于冷季(P<0.01);血浆铜含量与铜锌超氧化物歧化酶活性的相关系数为0.782 0,呈极显著正相关(P<0.01)。The activity of superoxide dismatase （SOD） in the blood of Tibelan sheep was determined in two different seasons and the relationship between SOD activity and Cu content was studied so as to understand the relationship of SOD with season and with Cu content and, based on this, offer recommendation about supplementation of Cu in sheep diet.
