Abstract: Improved extrusion-processed daily ration animal feeds are provided which include minor amounts of actives to ensure that an animal consuming the feed receives quantities of the actives sufficient to establish and maintain substantially constant concentrations of the actives in the animal's bloodstream. The feeds may be produced by extrusion with addition of minor quantities of one or more actives so as to uniformly distribute the actives throughout the extruded product.

Abstract: Improved daily ration mammal feeds are provided which include minor amounts of heartworm preventative drugs, ensure that a mammal consuming the feed receives quantities of drug sufficient to establish and maintain substantially constant concentrations of the drug in the pet's bloodstream. The feeds may be produced by extrusion with addition of minor quantities of heartworm preventative drug so as to uniformly distribute the drug throughout the extruded product. Ivermectin levels of from about 2-1500 ?g/kg of extruded feed are preferred.

Abstract: Improved daily ration mammal feeds are provided which include minor amounts of active such as heartworm preventative drugs, in order to ensure that a mammal consuming the feed receives quantities of active sufficient to establish and maintain substantially constant concentrations of the active in the pet's bloodstream. The feeds may be produced by methods including extrusion with addition of minor quantities of active therein so as to uniformly distribute the active throughout the product.

Abstract: Improved extruded human and animal foodstuff products are provided which include nutritional or therapeutically effective amounts of an active such as vitamins, vitamin precursors, and drugs such as tetracycline. The products are produced by extrusion, preferably with initial preconditioning followed by extrusion through an extruder equipped with a die assembly having an elongated, tubular body and an endmost restricted orifice die plate.

Abstract: A continuous mixer (32) is disclosed which can be used for mixing of incoming product streams (22, 24) of different characteristics respectively to yield a final product stream (26) of predetermined, consistent characteristics. The mixer (32) includes an elongated housing (42) having a pair of product input ports (50, 52) and an output (64), with a pair of elongated, axially rotatable, mixing screws (44, 46) located within the housing (42). The screws (44, 46) include a series of outwardly projecting mixing elements (114) preferably of pyramidal design and arrayed in a helical pattern along the length of the screws (44,46). The mixer (32) may be used in a processing system (20,200) having individual product lines (28,30,204,206) coupled to the mixer (32), and is especially useful for processing of incoming meat streams (22,24) of different fat/lean ratios, to give a final comminuted output stream (26) of an intermediate and essentially constant fat/lean ratio.

Abstract: Improved ivermectin-containing daily ration extruded feeds for domesticated household pets such as cats and dogs are provided so that a pet consuming the feeds receives quantities of ivermectin sufficient to establish and maintain substantially constant concentrations of the drug in the pet's bloodstream. The feeds are produced by extrusion with addition of minor quantities of ivermectin so as to uniformly distribute the drug throughout the extruded product. Ivermectin levels of from about 2-1500 &mgr;g/kg of extruded feed are preferred.
