Carbon dioxide emissions of lactating Holstein dairy cows with different total milk solids yields. Total CO2: P < 0.05, Total CO2/MW: P < 0.05, Total CO2/ECM: P < 0.05. MW: metabolic weight (kg). Total CO2, total CO2 production (g/d) = \( {\mathrm{CH}}_{4\left({\mathrm{CO}}_2-\mathrm{eq}\right)} \) (g/d) + CO2 production (g/d). ECM, Energy-corrected milk (kg/d) = milk yield (kg/d) × [(38.3 × fat (%) × 10 + 24.2 × protein (%) × 10 + 16.54 × lactose (%) × 10 + 20.7) ÷ 3140]
