The improvement depended on the kind of food the cows were given. Even the worst-polluting cows produced 33% less methane.(结果出乎意料地好。在某些情况下,奶牛产生的甲烷减少了82%。这种改善取决于喂给牛的食物。即使是污染最严重的奶牛产生的甲烷也少了33%。)”可知,研究人员进行这项研究是为了来测试...

Burger King said its lemongrass feed program could reduce methane created by cows by about33 percent. Scientists dove deeper into the fine print of the unpublished research, discovering that Burger King’s holy-grail lemongrass only reduces cow-produced methane emissions by about3 percent.Burger King...

What Is Methane? How Do Cows Emit Methane? Methane is emitted at dairy farms one of two ways. Enteric methane comes directly from the mouths of dairy animals. It is produced in the cow’s rumen through the digestion process. Think of it as a hearty burp after a good meal. ...
Dairy cows could be fed methane suppressants as part of a plan to cut down on greenhouse gases from farming. The government says it is planning to "encourage" the use of the suppressants - which can be made out of chemicals or natural ingredients such as seaweed - when ...

Methane is more than 80 times as potent as carbon dioxide in warming the atmosphere. About 25% of all methane is produced directly from fermentation by cows.
Cattle, such as dairy cows or beef cattle produce methane as a by-product of digestion. Cattle are ruminant animals, meaning they have specialized digestive systems that allow them to process foods that cannot be digested by humans and most other animals, like fresh grass and uncooked grain. ...
