近年来,随着我国奶牛养殖数量和规模的不断扩大,大量的粪尿作为肥料被广泛地施用在农田里,奶牛正常的生理活动产生的大量气体（CO2和CH4）也被排放到了空气中,但是反刍动物生产中排放的这些废物却对土壤、空气和水造成了日益严重的污染,其中粪、尿和气体中的碳、氮、磷、钾元素引起的环境污染问题更是不容忽视。笔者就以上存在的问题综述了奶牛生产中碳、氮、磷和钾对环境的污染,并从营养和饲养管理上提出相应的减排技术措施。

With the increasing of diary cows number in China, in cows production large quantities of the manure and urine are widely applied in the fields, as fertilizer, and plenty of the gases （CO2 and CH4）,which are produced by normal physiological activities in the rumen of dairy cows, release in the air.The waste result in increasingly serious pollution of soil, air and water, and the elements carbon （C）,nitrogen（N）,phosphorus （P）,and potassium （K） in the waste especially cause inevitable environmental contamination. The paper is a summary about pollution of C, N, P, and K in ruminant production, and the author also give some suggestions about how to reduce emission of C, N, P and K through nutrition regulation and improving feeding management.
