Descripción

The livestock contributes to greenhouse gas (GHG) emissions of anthropogenic origin, especially enteric methane (CH4). The objective of this work is to quantify in vitro the potential for reducing CH4 emissions through the inclusion of increasing levels of forage peanuts (FP) in a brachiaria-based diet. Samples were collected in two seasons of the year: summer and winter. Four field replications (pastures) were used. The samples were collected, dried, ground to 1mm and mixed to create FP inclusion levels of 0 %, 25 %, 50% and 100 %. The experimental design was a randomized blocks desing, with a 4x2 factorial arrangement and four replications. The samples were weighed on an analytical balance (0.5g), placed in filters and placed in 50 mL bottles.
