摘　　要： 天然沸石被应用于动物营养中以提高动物生产性能、有效预防氨和重金属毒性、吸附毒素、提高动物免疫力及畜舍环境。在过去的十年中,沸石作为霉菌毒素吸附剂一直是个热点话题,许多研究表明沸石或改性沸石对不同类型的霉菌毒素都有潜在的作用效果。近期研究表明沸石能够预防奶牛的代谢性疾病,同时能降低单胃动物粪尿中氮含量从而降低密闭畜舍内空气中氨含量。为了进一步拓展天然沸石的应用领域,本文综述了沸石提高动物健康状况的途径、详述了沸石提高动物健康状况的作用机制、分析了沸石在应用时的注意事项,为其在动物饲养及生产领域的应用提供科学依据。 Natural zeolites have been used in animal nutrition mainly to improve animals performance traits and they were also tested and found to be efficacious in the prevention of ammonia and heavy metal toxicities, absorption of poisonings as well as increase animal immunity and manure condition. During the last decade, their utilization as mycotoxin - binding adsorbents had been a hot topic of considerable interest and many published research data indicate their potential efficacy against different types of mycotoxins either as a primary material or after specific modifications. Recent findings support their role in the prevention of certain metabolic diseases in dairy cows, as well as their shifting effect on nitrogen excretion from urine to faeces in monogastric animals, which results in lower aerial ammonia concentration in the confinement facilities. In order to expand the application area of natural zeolite, this article reviewed the ways that improving animal health status through nature zeolite, described its mechanism of action, analyzed announcements when using natural zeolite as feed additive thus supporting scientific basis for its using in the area of animal raising and production.
