Emisión de metano entérico en sistemas pastoriles: estrategias de reducción con potencial práctico

Abstract

Animal production must develop more efficient systems and less harmful with the environment. Enteric methane represents an energy loss for ruminant and it is a gas of greenhouse effect. Therefore, the objective of this review was to consider strategies that allow reduce enteric methane production in pastoral systems. The enteric methane emissions are modified by botanical characteristics and management. Therefore, the inclusion of tanniferous leguminous, efficient management of pastures and the increase in animal productivity are tools that allow decreasing methane production per unit of product. In pastoral systems other strategies reported in the literature should be investigated more closely.
