Abstract

The objective of this study was to determine the effects of currently used anthelmintics on production performance, carcass quality characteristics, and species diversity in western Canadian feedlot calves. Changes in climate and anthelmintic susceptibility are changing the epidemiology of gastrointestinal nematodes in livestock. However, the production impact of gastrointestinal nematodes in beef cattle from western Canada has not been studied in decades.
