Resumen
- Ruminants have the capability to ferment structural carbohydrates found in forages and obtainfrom them a usable form of energy to produce high quality food, i.e milk and meat (Kamra et al., 2012).However, as a gaseous by-product from the enteric fermentation of those carbohydrates, methane is produced in a significant proportion, being considered as one of the most important greenhouse gases (GHG). In Colombian tropical livestock, inclusion of legumes in on poor quality grasses diets based have allowed an improvement of their nutritive quality, besides enteric methanogenesis reduction because their content of condensed tannins (CT); however, this is not always associated with all tropical legumes (Hess et al., 2002).Therefore, the purpose of this study was evaluating the effect of including the tropical legume Arachis pintoi in diets based on Megathyrsus maximusy Brachiaria humidicolaover methane in vitro production.
