在牛奶生产的过程中,奶牛胃肠道是甲烷产生的主要场所.本文概述了日粮NFC、淀粉、蛋白、纤维、脂肪、添加剂等营养调控措施和DMI、健康、牛群结构等管理措施及产奶量、饲料转化效率和反刍行为等遗传选择措施对奶牛胃肠道甲烷减排的影响.
A Comprehensive Review of Scientific Studies on Strategies for Reducing Methane Emissions in the Gastrointestinal Tract of Dairy Cows
In the process of milk production,the gastrointestinal tract of dairy cows serves as the primary source of methane emissions.Therefore,this paper provides a comprehensive overview the effects of various nutritional regulation measures,including dietary NFC,starch,protein,fiber,fat and feed additives;management measures such as DMI,health and herd structure;and genetic selection measures such as milk yield,feed conversion efficiency and rumination behavior on mitigating methane emissions of dairy cows.
