中文摘要：

硒是动物必需微量元素,与动物许多重要的生物学功能密切相关。硒在反刍动物消化道内消化吸收时,受到瘤胃微生物的影响,部分硒转化为不溶性物质,不能被动物吸收利用,因此在饲养过程中,反刍动物相对于单胃动物,应该更加注意补充硒。文章结合国内外研究进展,综述硒在反刍动物营养中的应用,在饲养实践中合理利用硒,实现反刍动物高效、健康养殖。

英文摘要：

Selenium is an essential trace element for animals, closely related to animals in many impor-tant biological functions.Selenium in ruminant digestion and absorption in the digestive tract, underthe influence of rumen microbes.some selenium translated into insoluble substances, can not be ab-sorbed by the animal, so in the breeding process, with respect to ruminants monogastric animals,should pay more attention to selenium supplementation.Based on the latest research progress both athome and abroad, we summarized the application of selenium in ruminant nutrition, rational utilizationof selenium in breeding practice, implement ruminants, and efficient health cultivation. feeding practic-es in the rational use of selenium to achieve ruminants efficient and healthy farming.
