These methanogenic bacteria associated with rumen protozoa are apparently responsible for 9 to 25% of methanogenesis, but this can be reduced by around 13% when the protozoa are killed; however, this reduction occurs when the animal consumes starchy diets, which is when the protozoa generate more [H.sub.2], which is not the case when the diets are high in forage resulting in less methane formation (30).
