Pre\u2010treatment FECs were monitored on 14 dairy farms. Anthelmintic resistance was assessed on 11 of the farms. Control FECs were compared with anthelmintic FECs at 14\u2009days post\u2010treatment with doramectin (injectable), levamisole (oral), fenbendazole (oral) and a levamisole\/abamectin combination (pour\u2010on). Results demonstrate a strong level of anthelmintic resistance, with at least one class of anthelmintic failing to achieve a 95% reduction in FEC in one or more gastrointestinal nematode species. Doramectin was fully effective against <jats:italic>Ostertagia<\/jats:italic>, but <jats:italic>C. oncophora<\/jats:italic> displayed resistance in 91% of the farms. Conversely, levamisole was fully effective against <jats:italic>C. oncophora<\/jats:italic>, but <jats:italic>Ostertagia<\/jats:italic> displayed resistance in 80% of the farms. Fenbendazole resistance was present in both <jats:italic>C. onocphora<\/jats:italic> and <jats:italic>Ostertagia<\/jats:italic> in 64% and 70% of the farms, respectively. <jats:italic>Trichostrongylus<\/jats:italic> showed low resistance, occurring in doramectin (14%) and levamisole\/abamectin combination (14%). This study confirms that anthelmintic resistance is common. Regular FEC reduction testing is recommended to monitor and guide decision\u2010making for appropriate anthelmintic usage.<\/jats:p>","DOI":"10.1111\/avj.13162","type":"journal-article","created":{"date-parts":[[2022,4,5]],"date-time":"2022-04-05T08:50:21Z","timestamp":1649148621000},"page":"283-291","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Anthelmintic resistance of gastrointestinal nematodes in dairy calves within a pasture\u2010based production system of south West Western Australia"],"prefix":"10.1111","volume":"100","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3218-0707","authenticated-orcid":false,"given":"M.","family":"Mauger","sequence":"first","affiliation":[{"name":"School of Veterinary Medicine, College of Science, Health, Engineering and Education Murdoch University  Murdoch Western Australia Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Kelly","sequence":"additional","affiliation":[{"name":"Boehringer Ingelheim Animal Health Australia Pty.
