Abstract
Serum copper was generally higher in lambs affected with ovine white-liver disease (OWLD) than in cobalt/vitamin B12 supplemented lambs grazing the same pastures. Although the copper content of the grass was very low on the OWLD pastures, dosing lambs with Cu alone resulted in worsening of the clinical condition and aggravation of clinical pathology. Dosing with selenium had no effect on OWLD. Dosing with a combination of Co, Se and Cu resulted in normal lamb growth and normal laboratory tests. Lambs growing well on other pastures (H) showed elevated serum Cu when they were subclinically B12 deficient.
摘要
患绵羊白肝病（OWLD）的羔羊血清铜含量通常高于在同一牧场放牧的补充了钴/维生素B12的羔羊。尽管OWLD牧场的草铜含量非常低，但仅给羔羊投喂铜会导致临床状况恶化和临床病理学加重。投喂硒对OWLD没有影响。同时投喂钴、硒和铜可使羔羊生长正常且实验室检查结果正常。在其他牧场（H）生长良好的羔羊在亚临床维生素B12缺乏时血清铜升高。
