摘要
对无机铜及氨基酸螯合铜在养猪业中的营养及应用进展进行综述 ,虽然猪对铜的需要量较低 ,但具有不可缺少的作用。高剂量铜对猪则具有明显的促生长效果 ,同时存在比较明显的缺点 ,而氨基酸螯合铜生物效价较高 ,具有较大的实际应用前景。
The role of copper is impotant for swine,and feeding high dietary concentrations of copper markedly improves pig's performance.But the principles are unclearly.The Cu AA complex was more effective than CuSO 4 in enhancing pig performance,and has a hoping future.
