The essentiality of zinc for animals has been recognized over 80 years. Zinc is an essential trace element that is a component of many enzymes and is associated with the various hormones. Apart from the nutritional function, zinc has antimicrobial property and often be supplemented in diets in the quantities greater than which is required to meet the nutritional requirement, especially for weaning pigs. This review will focus on the application of pharmacological zinc and its mechanisms which may be responsible for the effects of zinc on performance and health of monogastric animals. Various novel sources of zinc in non-ruminant animal production will also be discussed. These should assist in more precisely formulating feed to maximize the production performance and to maintain the health condition of monogastric animals.
锌对动物的重要性在80多年前就已被认识到。锌是一种必需的微量元素，是许多酶的组成成分，并与多种激素相关。除了营养功能外，锌还具有抗菌特性，并且在日粮中经常以高于满足营养需求所需的量进行添加，尤其是对于断奶仔猪。本文综述将聚焦于药理剂量锌的应用及其可能对单胃动物生产性能和健康产生影响的作用机制。同时也将讨论非反刍动物生产中各种新型锌源。这些有助于更精确地配制饲料，以最大限度地提高生产性能并维持单胃动物的健康状况。
