Résumé
Methane produced by ruminants (goats, sheep, cattle) is a significant component of greenhouse gas emissions. In addition, in Indonesia, there is a shortage of livestock feed. We therefore tested whether harvest waste from tropical horticulture could be incorporated into ruminant diets and perhaps reduce methane production. Using in vitro techniques, we screened a variety of waste sources and chose the best candidates by comparing them to 100% Leucaena, a common ruminant forage in Indonesia. We found that banana and guava waste, when mixed with Leucaena, can be digested in the rumen and also reduce methane production.
