摘  要:
高铜对猪的促生长特性被发现后,一直作为廉价、高效的预防性饲料添加剂得到广泛的应用与研究。近年来,屡有报道指出长期补饲高铜不仅降低其促长效果,还会导致大量铜在动物组织器官积蓄,产生毒性,最终降低猪的生长性能。本文综述了长期补饲引起的高铜抑制猪生长的机制研究进展。

摘  要:
High copper feed has been widely used as an inexpensive and highly effective feed additive to promote growth performance of pigs.However,long-term feeding of high-copper feed may reduce the growth promoting effects of copper,time-dependent accumulation of copper in animal tissues and organs,and copper toxicity there by reducing the growth performance of pigs.Due to the widespread effects of high-copper supplementation in animals?diets,the benefits and drawbacks of high-copper feeding in pigs have been reported in several studies.This paper reviews the research progress of long-term supplementation of high-copper on the growth of pigs and provides some suggestions and further research directions.
