Abstract
Disclosed is an NPN delivery system for a ruminant animal, the system comprising a complex of a zein-containing species or other proteinaceous species with a nitrogenous species. The NPN from the nitrogenous species is present in the complex in a form such that at least a portion of the NPN is not initially bioavailable to the rumen upon introduction of the system into the rumen of the ruminant animal. Preferably, the delivery system comprises a complex of urea with corn gluten. Also disclosed are methods for preparing an NPN delivery system for a ruminant animal.
