Feed chemical composition is associated with methane (CH4) formation in the rumen. and thus CH4 yields (Ym; CH4 emitted from per unit of dry matter intake) could be predicted using near-infrared reflectance spectroscopy (NIRS) of feeds fed to ruminants. Two databases of NIRS data were compiled from feeds used in experiments in which CH4 yields had been quantified in respiration chambe... https://www.collegenotprison.com/product-category/testiere/
