摘要
选用510只1日龄仙湖3号商品肉鸭,随机分为5组(公母各半),Ⅰ至Ⅴ组日粮中含铜水平(mg／kg)分别为7,150,200,250和300。试验结果表明,肝脏、肌肉与日粮铜水平相关系数分别为0.889,0.772,而屠宰性能与对照组差异不显著。
510 one-day Xianhu Ducks were randomly divided into five groups . Ⅰto Ⅴ groups were fed on basic diet with additive copper level 7,150,200,250 and 300mg/kg respectively. The result showed that liver copper and muscle copper increased as diet copper level were raised. The correlation coefficient between them were 0.889,0.772 respectively, and no significant differences of slaughter index were found among the five groups.
