饲粮营养调控减少反刍动物甲烷排放研究进展

Research Progress on Reducing Methane Emission from Ruminants by Dietary Nutrition Regulation and Control

温室效应是改变地球生物生存环境、导致生态危机的重要原因之一。畜牧业生产中产生的甲烷、CO_2等温室气体占全球人造温室气体的18%。文章就近些年降低反刍动物甲烷排放的最新方法、研究进展和存在的问题进行了综述,尤其针对海藻作为新型饲料添加原料在降低甲烷排放方面的效果和应用现状进行归纳介绍,以期为降低反刍动物甲烷排放、发展绿色畜牧业以及寻求新的技术解决方案提供参考依据。

Greenhouse effect is one of the important reasons for changing the living environment of the earth,leading to ecological crisis.The production of methane,CO 2 and other greenhouse gases from animal husbandry account for 18%of the world's man-made greenhouse gases,therefore,the animal husbandry methane emission is a global problem to be solved.In this paper,the latest methods,research progress and existing problems of reducing methane emission in ruminants in recent years are reviewed.In particular,the effect and application status of algae as a new feedstock in reducing methane emission are summarized in order to provide a reference for the reduction of ruminant methane emissions and the development of green animal husbandry,as well as in the search of new technological solutions.
