摘要: 为探讨青藏高原放牧绵羊矿物元素含量变化规律,本研究分春、夏、秋3季采集青海湖南岸绵羊毛、血清、粪、尿样品,测定Cu、Mn、Zn、Mg、Se和Mo的含量,并考查了各元素的相关性。结果表明: 血清中除Mn、Se,其余元素在季节间差异不显著;毛中除Se其余元素差异显著,尿中各元素均差异显著,粪中除Zn其余元素差异显著(P<0.05)。同一样品内不同元素间的相关性分析表明,春季元素间的正相关较夏季和秋季多;粪内元素间关联度较高;Mg元素与其他元素的协同关系较多,而Se元素则相反。同一元素在不同样品间的相关性表明:尿中矿物元素与其他样品显著相关;Zn、Se与其他元素相关关系紧密,而Mo元素则不甚紧密。综上,对于放牧绵羊而言,推荐尿液作为矿物元素实时监测指标;春季适时补充矿物质,可将Se与其他元素分开以避免相互拮抗。

Abstract: In order to explore the change pattern of mineral elements from hair, serum, feces and urine on grazing sheep of Qinghai-Tibet Plateau, the contents of Cu, Mn, Zn, Mg, Se and Mo in hair, blood, feces and urine collected in spring, summer and autumn from sheep on the southern shore of Qinghai Lake were measured, and the correlations of different elements in the same samples and the same elements in different samples were calculated. All elements showed no significant difference except the Mn and Se in serum among seasons, and all elements in urine, hair and feces showed significant difference except Se in hair and Zn in feces (P<0.05). These results showed that the content of each element in serum was much easier to keep constant than that in hair, feces and urine. From the correlation of different elements in the same samples, the positive relationship in spring was more than that in summer or autumn, and the related degree of each element in feces was higher than others, and the Mg had more synergic effect with other elements while the Se had less. From the correlation of the same element in different samples, the correlation of each element between urine and other sample was of significance. Zn and Se had a tight relationship with other elements while Mo did not. In conclusion, the urine is recommended as an index to monitor the grazing sheep minerals and Se should be separated from other elements to avoid antagonism when adding minerals in spring.
