Method and composition for increasing the proportion of dietary ingredients that are resistant to degradation by ruminal microorganisms

Feed ingredients that are otherwise susceptible to degradation by ruminai microorganisms are combined with mineral hydrates (or oxides) and water, and processed through a pin mixer, pellet mill, extruder, or other suitable device to produce agglomerated particles. The ruminant animal feed which is so produced effectively increases the proportion of dietary ingredients presented for digestion and absorption within the post-ruminal digestive tract of the animal by inhibiting premature digestion by microorganisms inhabiting the rumen.
