摘　　要：为了研究相同放牧条件下蒙古牛和其他品种牛血清生化指标的变化,试验采用酶标仪测定了蒙古牛、安格斯牛和海福特牛血清8种生化指标的含量。结果表明,蒙古牛血清中胰高血糖素(glucagon,GC)、甘油三酯(triglyceride,TG)、尿素氮(blood urea nitrogen,BUN)含量均显著低于安格斯牛和海福特牛(P<0.05)。而蒙古牛血清中生长激素(growth hormone,GH)含量显著低于海福特牛(P<0.05),与安格斯牛之间无显著差异(P>0.05);蒙古牛血清中血糖(blood glucose,BG)含量显著高于安格斯牛(P<0.05),与海福特牛之间无显著差异(P>0.05)。此外,蒙古牛血清中胰岛素(insulin,ISU)含量有高于安格斯牛和海福特牛的趋势,但差异不显著(P>0.05);三碘甲状腺原氨酸(triiodothyronine,T_3)、甲状腺素(thyroxine,T_4)含量有低于安格斯牛和海福特牛的趋势,但差异不显著(P>0.05)。In order to characterize the serum biochemical parameters of Mongolia Cattle and other breeds of cattle under grazing condition, eight serum biochemical parameters of Mongolia Cattle, Angus Cattle and Hereford Cattle were determined by Microplate reader. The results showed that compared to Angus Cattle and Hereford Cattle, Mongolia Cattle had significantly lower serum content of GC, TG and BUN （P〈0.05）; the serum content of GH in Mongolia Cattle was significantly lower than that of Hereford Cattle （P〈0.05）, and was lower than that of Angus Cattle （P〉0.05）; the serum content of BG in Mongolia Cattle was significantly higher than that of Angus Cattle （P〈0.05）, and was higher than that of Hereford Cattle （P〉0.05）. Compared to Angus Cattle and Hereford Cattle, Mongolia Cattle had higher serum content of ISU and lower serum content of T3 and T4, but no significant differences were observed （P〉0.05）.
