Abstract

Doramectin pour-on solution (Dectomax® Pour-On) is an endectocide with a broad spectrum of activity against gastrointestinal nematodes and arthropods of cattle and duration of activity indications against several nematodes. To evaluate the efficacy of doramectin pour-on solution in decreasing pasture parasite contamination and resulting calf performance, two studies with similar experimental designs were conducted in cow-calf herds in Prairie, Mississippi (MS) and Parma, Idaho (ID). These studies were 168 and 140 days in duration for MS and ID, respectively.
