Investigation on the Abundance and Deficiency Status of Mineral Elements in Yaks in Hongyuan County of Sichuan Province
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 with-out obvious diseases were selected from Hongyuan County.The contents of trace elements(iron,manga-nese,cobalt,molybdenum,copper,zinc,and selenium)in whole blood and the mass concentrations of vita-mins(A,D2,D3,D,E,K1 and K2)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 investiga-ted yaks were 551,0.06,0.002,0.04,0.49,2,and 0.1 mg/kg,respectively.The contents of vitamins A,D2,D3,D,K1 and K2 in serum were 428.64,59.57,19.2,78.78,1.37,and 0.15 ng/mL,respectively,and the con-tent of vitamin E was 5.28 μg/mL.These results indicated that the investigated yaks had deficiencies in manganese,cobalt,copper,zinc,and vitamin D3.Therefore,local herders should reasonably adjust the daily diet and feed more green vegetables to supplement the relatively deficient trace elements and vitamins.关键词
