Abstract

The effect of 6 methods of copper supplementation on copper status was examined in Merino sheep at pasture. Plasma copper concentrations were not affected by any of the treatments. Liver copper concentrations in sheep given an oral dose of 3 g of oxidised copper wire particles were significantly greater than those of untreated sheep for the duration of the experiment of 80 weeks. Subcutaneous injections of 18 mg of copper as diethylamino cupro -oxyquinoline sulphonate produced small, transient increases in liver copper. Single oral doses of 150 mg of copper as copper sulphate or 30 mg of copper as copper oxychloride produced little or no detectable increase in liver copper. Liver copper concentrations of untreated sheep were lowest in winter, apparently associated with increased damage to the abomasum, as indicated by raised plasma pepsinogen activities.

摘要

在放牧的美利奴绵羊中研究了6种补铜方法对铜状态的影响。血浆铜浓度不受任何一种处理的影响。在为期80周的实验期间，口服3克氧化铜丝颗粒的绵羊肝脏铜浓度显著高于未处理的绵羊。皮下注射18毫克的二乙氨基铜氧喹啉磺酸盐形式的铜，会使肝脏铜出现小幅度的短暂增加。单次口服150毫克硫酸铜形式的铜或30毫克氯氧化铜形式的铜，几乎不会使肝脏铜浓度出现可检测到的增加，或根本不会使其增加。未处理绵羊的肝脏铜浓度在冬季最低，这显然与皱胃损伤增加有关，血浆胃蛋白酶原活性升高表明了这一点。
