摘　　要：铜是所有生物体的必需微量元素,其对猪的促生长作用较为明显。文章论述了日粮中添加不同浓度的硫酸铜对仔猪生长期、育肥前期和育肥后期的生产性能,各组织铜沉积规律的影响。Copper is an essential trace element in all organisms, which can promote the growth of pigs. In this paper, the effects of different concentrations of copper sulfate on the production performance of piglets in the growth period, the pre fattening stage and the late fattening stage, and the influence of copper deposition in various tissues were reflected in the dose response curve.

关 键 词：铜水平 剂量反应曲线 生产性能 组织铜沉积
