Methane production and fermentative parameters of Tithonia diversifolia/Pennisetum purpureum silage enriched or not with lactic acid bacteria strains

摘要

Tithonia diversifolia (TD) has great potential for feeding ruminant and monogastric because it has a high content of protein and minerals and a good acceptance by the animals for consumption. To select the best fermentation parameters of the materials favoring the availability of nutrients for rumen microorganisms we evaluated the association of TD and Pennisetum purpureum (PP) for silage making and the dynamics of gas production.
