Does the feed given to the animal affect the production of methane gas?
Manure from animals fed high energy diets generally would be easier to digest than manure from animals fed a high forage diet. Manure from animals on a high forage diet will have a high content of partially digested lignocellulosic material. The animals will have utilized the most easily digested parts of the forage, leaving the most recalcitrant parts in the manure.
