摘　　要：选用560只1日龄肉用乌骨鸡,采用单因子多水平随机化试验设计,研究铜致肉用乌骨鸡中毒的效应,观察了雏鸡中毒的临床症状、病理学变化、生产性能、血液常规指标的变化。试验结果表明:日粮含铜600 mg/kg,可对肉用乌骨鸡产生毒性作用,800 mg/kg以上可引起急性中毒反应,1200 mg/kg可导致急性中毒死亡;日粮含铜400mg/kg尽管有促生长作用,但对肉用乌骨鸡可产生蓄积毒;日粮含铜200 mg/kg对肉用乌骨鸡有明显促生长作用,且无任何不良反应。An experiment was conducted with 7 × 1 factorial design to study the effect of dietary copper on growth performance,clinical symptoms,clinical pathology and routine blood-test indexes of black bone broilers. The experiment results indicated that the dosage of copper poisoning in black bone broiler was 600 mg/kg and the lethal dosage of copper was 1 200 mg/kg in diet. Acute copper poisoning occurred,as long as the copper content of black bone broiler was 800 mg/kg in diet. 400 mg/kg,cumulating poisoning occurred,although encouraged the speed of growth. 200 mg/kg copper in diet could promote black bone broilers growth,without any toxicity.
