铜(Cu) 关于铜在动物营养方面作用的认识已有了进展,尤其自澳大利亚开始安装电话线以后,在新装的电话线下的牧草比那些远离电话线的牧草要茂盛到多,经土壤测试得知,电话线上的铜经雨水的淋溶进入到土壤,这些铜离子对于牧草的生长是有利的.不久又开展调查:以证实缺铜与动物健康是否有关.当时,澳大利亚的绵羊有一种流行病,叫地方性动物共济失 Copper (Cu) Knowledge of the role of copper in animal nutrition has progressed, especially since the telephone lines were installed in Australia after the installation of forage lines under the newly installed telephone lines to flourish more than pasture farther away from the telephone line.
