Abstract
The project aims to quantify greenhouse gases (GHG) methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) and calculate the carbon footprint in beef cattle production systems. GHG emissions will be calculated as the sum of CH4 produced by enteric fermentation and manure; N2O emissions from feces and urine deposited on pasture or in feedlots, and N2O from nitrogen fertilizer applica…
