Abstract: The present invention relates to the field of reduction of methane emission in ruminants. Particularly. it relates to the administration of gossypol in an amount of at least 7.5 g gossypol/animal/day to a ruminant for reducing the production of methane emanating from the diges-5tive activities of said ruminant.
