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 μg/kg of extruded feed are preferred.
