Methane emission, nutrient degradation and nitrogen turnover in dairy cows and their slurry at different milk production scenarios with and without concentrate supplementation

Methane emissions from dairy cows, including storage of their slurry, contribute significantly to the global greenhouse gas budget. Supplementation of diets with concentrate often diminishes enteric methane emissions from cows, but it may simultaneously enhance slurry methanogenesis because this is...
