Methane emissions are the primary factor influencing the carbon footprint of cattle. They have been
reported to account for 55% [14] to 92% [15] of the carbon footprint, with the majority of the CH4
emissions arising from enteric fermentation. Depending on a suite of factors including feed quality,
management practices, animal activity, and animal genetics, 3% [11] to 9.5% [16] of the energy
consumed by cattle is lost as CH4. Adopting feeding practices that minimize the loss of CH4 improves
animal productivity and reduces the carbon footprint of cattle.ctice
