Purpose: Livestock production is a recognized source of environmental impact, and this sector indirectly involves approximately 5 million people in Brazil. Livestock production includes nearly 1.5 million milk producers that use several different production systems. We chose the southern region of Brazil to evaluate the carbon footprint (CF) per 1 kg of energy-corrected milk (ECM) at the farm gate for different dairy production systems with the use of a good level of technology.
Methods: The dairy production systems were confined feedlot system, semi-confined feedlot system (including some grazing), and pasture-based grazing system. A sensitivity analysis of the dry matter intake (DMI) in each farming system and an uncertainty analysis based on a Monte Carlo (MC) simulation were performed to complement the discussion. The standards ISO 14040: 2006 and ISO 14044: 2006 were used for the comparative life cycle assessment (LCA) focused on the CF. The LCA software tool SimaPro 7.3.3 was used. Sensitivity analyses were conducted on input data for total digestible nutrients (TDN) and crude protein (CP) based on values from the literature.
Results and discussion: The comparative LCA showed that the confined feedlot system had a lower CF than the other systems studied. Total greenhouse gas emissions were 0.535 kg CO2e kg ECM for the confined feedlot system, 0.778 kg CO2e kg ECM& for the semi-confined feedlot system, and 0.738 kg CO2e kg ECM for the pasture-based system without considering the impact from direct land use change (dLUC). When considering these emissions, the CFs for grain and cottonseed production showed CF increases of 45.0, 36.9, and 37.3 % for the confined feedlot, semi-confined feedlot, and pasture-based systems, respectively. The results from the MC simulations showed low uncertainty through variations in TDN and CP. The coefficient of variation was 1.1 % for the confined feedlot, 0.7 % for the semi-confined feedlot, and 1.0 % for the pasture systems.
Conclusions: The uncertainties were due mainly to variations in N2O emissions from manure for the three systems. The CF in Brazilian systems was lower than almost all the results found in the literature, even when impacts from the dLUC were considered. The lowest CF in this case study was due mainly to the emission factor used for enteric fermentation.

Durante o mês de Fevereiro o fenômeno El Niño diminuiu a intensidade na sua área de atuação no Pacífico central, porém continuou sem influenciar a chuva no Sul do Brasil. O primeiro dia do mês apresentou os valores mais significativos de Fevereiro (69,6 mm em Campo Belo do Sul e 44,8 mm em Pinhal da Serra), devido à frente fria que chegou a Santa Catarina no último dia de Janeiro trazendo destruição ao Planalto Sul catarinense. Durante o restante do mês a chuva foi frequente, bem distribuída com totais diários entre 4,0 mm e 30,0 mm. As pancadas de chuva convectiva, associadas ao calor da tarde, típicas de verão contribuíram para manter boa parte dos dias com mais nebulosidade e registro de chuva. A chuva ficou distribuída em 16 dias na estação de Campo Belo do Sul e 19 dias em Pinhal da Serra, com valor diário superior a 0,5mm. A chuva acumulado no mês foi de 209,2 mm em Campo Belo do Sul e de 176,4 mm em Pinhal da Serra. Os maiores volumes horários de chuva ocorreram devido a núcleos de instabilidade. No dia 23/02 o total de chuva em uma hora foi de 30,8 mm em Campo Belo do Sul e chegou a 28,2mm em Pinhal da Serra no dia 15/02. A chuva foi causada por quatro frentes frias, cavados ou áreas alongadas de baixa pressão e as pancadas de chuva associadas ao calor da tarde na região da Baesa. Ocorreram menos temporais em Fevereiro do que em Janeiro na região da Baesa. |
