【摘要】：铜是猪重要的必需微量元素之一。它不仅参与造血功能,而且作为许多重要酶的辅酶因子,参与机体抗氧化、糖脂代谢调控、骨骼矿化、黑色素合成、毛发形成等复杂的功能,饲粮添加高水平铜的促生长和免疫功效,在生产中表现出诸多优势。但生产者往往忽视了它另一面的负效应:打乱了猪代谢的平衡而产生中毒症状,其一是危害猪本身健康,其二是影响肉品安全,甚至危害食用者的健康,其三是产生了难以治理的高铜排泄等环境污染问题。
[Abstract]:Copper is one of the essential trace elements in pigs. It not only participates in hematopoietic function, but also as a coenzyme factor of many important enzymes, participates in the body antioxidation, the sugar and lipid metabolism regulation, the skeleton mineralization, the melanin synthesis, the hair formation and so on complex function. The growth-promoting and immunological effects of high-level copper supplementation in diet showed many advantages in production. But producers often ignore the negative effects on the other side: they disrupt the balance of metabolism in pigs and produce toxic symptoms, one of which is harmful to the pig's own health, the other to the safety of meat, and even to the health of the user. Third, it is difficult to control the high copper excretion and other environmental pollution problems.
