    Keywords : mjölkko; metan; minska; reducera; 3-NOP; 3-nitrooxypropanol; mjölkkvalitet; mjölkavkastning;

    Abstract : Att minska metanutsläppen från världens mjölkkor ger möjligheten att minska jordbrukets klimatpåverkan. Kornas metanutsläpp från fodersmältningen ger en kraftigare värmande effekt på atmosfären än vad koldioxid gör då metan är ca 32 gånger så kraftfull. Eftersom metan är en kortlivad gas kan minskning av den visa snabba resultat. READ MORE
