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.
