Intensities of methane emissions from Canchim steers finished in feedlots.

Livestock is responsible for 14.5% of total anthropogenic emissions of greenhouse gases - GHG (FAO, 2013). Studies evaluating GHG from different lineages within of the same cattle breed are scarce. The objective of this study was to evaluate the intensities of methane emissions (kg CH4/kg Live Weight) from two lineages of Canchim steers (3/8 Nelore + 5/8 Charolais).
