A device for producing a high density compact livestock feed from a loose granular material according to various embodiment can include a source for supplying a loose granular material to be treated. The high-energy treatment alters the substrate’s physical properties so that the inner core provides greater toughness and the outer region provides greater hardness, and greater abrasion resistance. An automated exchange director provides for real time matching of specific products in the database with corresponding bids from system users, and executes trades of accepted matches for identified units of the specific products.
