Propostas de seleção para redução da produção de gases de efeito estufa em bovinos de corte

Abstract

Selection to reduce greenhouse gas production in beef cattle is a strategy currently used to make production efficient and sustainable. Livestock, especially the production of beef cattle, is one of the main emitters of these polluting gases, such as carbon dioxide, nitrous oxide and methane gas, the latter one of the most produced and that generate a great impact on the sustainability of this chain. This literature review has as its main objective the collection of information and data on how selection, either indirectly by performance and reproductive characteristics or directly by the production of gases, can impact on the mitigation of greenhouse gases produced, for this, specialized literature was used to review the subject addressed. The selection of characteristics of zootechnical interest, which present high values of heritability, both for productive traits or in parallel to reduce these emissions, have been explored in several studies related to the subject. Thus, studies are needed using methodologies that collect information necessary for the selection of such parameters, such as methane measurement techniques or life cycle assessment that can evaluate these characteristics that present results for the economic and environmental sustainability of beef cattle production systems.
