Proceedings... Brasília, DF: Embrapac2016  ap.429-430.  a(Embrapa Gado de Corte. Documentos, 216).  aAt present there is a need to increase the productivity of systems due to an increasing demand for food and a shrinking area available for agricultural production. One solution is confinement of livestock and the use of genetic groups that are more efficient at transforming feed into product (meat). Feed efficiency may be related to enteric methane emissions, which generate energetic losses when produced by the animal. The objective of this study was to measure enteric methane emissions from crossbred cattle bred from different breeds of bulls.  aConfinamento  aGado Mestiço  aEficiência genética  aEmissão de metano entérico1 aGUILARDI, J.
