中文摘要:

      通过测定牦牛全血中微量元素和血清中维生素的含量并进行分析，从而了解四川红原县牦牛全血中微量元素和血清中维生素的盈缺状态。选取红原县 4~6 岁无明显疾病的牦牛共 60 头，测定牦牛全血中微量元素铁、锰、钴、钼、铜、锌、硒含量和血清中维生素 A、D?、D?、D、E、K?、K?的质量浓度。结果显示，所调查的 60 头牦牛全血中铁、锰、钴、钼、铜、锌、硒的平均含量分别为 551、0.06、0.002、0.04、0.49、2 和 0.1 mg/kg，血清中维生素 A、D?、D?、D、K?、K?的含量分别为 428.64、59.57、19.2、78.78、1.37 和 0.15 ng/ml，维生素 E 含量为 5.28μg/mL，表明所调查的牦牛均存在锰、钴、铜、锌以及维生素 D?的缺乏，因此当地牧民应合理调配日粮，多投喂青绿蔬菜，以补充相对缺乏的微量元素和维生素。

英文摘要:

      Abstract：By measuring and analyzing the contents of trace elements in whole blood and vitamins in serum of yaks, the deficiency or sufficiency status of trace elements in whole blood and vitamins in serum of yaks in Hongyuan County of Sichuan Province was investigated. A total of 60 yaks aged 4-6 years without obvious diseases were selected from Hongyuan County. The contents of trace elements (iron, manganese, cobalt, molybdenum, copper, zinc, and selenium) in whole blood and the mass concentrations of vitamins (A, D?, D?, D, E, K? and K?) in serum were determined. The results showed that the average contents of iron, manganese, cobalt, molybdenum, copper, zinc, and selenium in the whole blood of the 60 investigated yaks were 551, 0.06, 0.002, 0.04, 0.49, 2, and 0.1 mg/kg respectively. The contents of vitamins A, D?, D?, D, K? and K? in serum were 428.64, 59.57, 19.2, 78.78, 1.37, and 0.15 ng/ml, respectively, and the content of vitamin E was 5.28μg/mL. These results indicated that the investigated yaks had deficiencies in manganese, cobalt, copper, zinc, and vitamin D?. Therefore, local herders should reasonably adjust the daily diet and feed more green vegetables to supplement the relatively deficient trace elements and vitamins.
