Abstract

During the 1986 lambing season, 33 Michigan sheep producers submitted all lambs that had died before weaning to the Michigan State University Diagnostic Laboratory for necropsy. Inductively coupled argon plasma emission spectroscopy was used to measure 22 elements in the liver of 888 of the lambs submitted. Mean concentrations of each element were established and compared with literature values of established deficient, normal, and toxic concentrations. Mean values in milligrams per kilogram of wet weight were as follows: Al, 3.843; As, less than 1; Ba, 0.176; Ca, 128.2; Cr, 0.778; Cu, 56.82; Fe, 491.6; Hg, less than 2; K, 2,150; Mg, 138.4; Mn, 2.776; Mo, 0.489; Na, 1,384; P, 2,583; Pb, 1,453; Sb, less than 1; Tl, less than 5; Zn, 68.31. In only 11 lambs did the liver contain As, B, Cd, Co, Hg, Sb, Se, or Tl in detectable concentrations.

摘要

在1986年的产羔季节，33位密歇根州的养羊户将所有在断奶前死亡的羔羊送到密歇根州立大学诊断实验室进行尸检。使用电感耦合氩等离子体发射光谱法对送检的888只羔羊肝脏中的22种元素进行了测量。确定了每种元素的平均浓度，并与既定的缺乏、正常和中毒浓度的文献值进行了比较。每千克湿重的平均值（毫克）如下：铝，3.843；砷，小于1；钡，0.176；钙，128.2；铬，0.778；铜，56.82；铁，491.6；汞，小于2；钾，2150；镁，138.4；锰，2.776；钼，0.489；钠，1384；磷，2583；铅，1453；锑，小于1；铊，小于5；锌，68.31。只有11只羔羊的肝脏中含有可检测浓度的砷、硼、镉、钴、汞、锑、硒或铊。
