Abstract
in English, French

Blood was drawn from 1530 dairy cows in 51 herds. For antibodies against bovine leukemia virus, Mycobacterium avium subspecies paratuberculosis, and Neospora caninum, 37.4%, 2.7%, and 5.6% of cows were test positive, respectively, while 29.2% of herds had unvaccinated animals with > or = 1:64 for bovine viral diarrhea virus.

Résumé — Séroprévalence des anticorps contre le virus de la leucémie bovine, le virus de la diarrhée virale bovine, Mycobacterium avium sous espèces paratuberculosis et Neospora caninum chez les bovins laitiers de la Saskatchewan. Du sang a été prélevé chez 1530 vaches laitières de 51 troupeaux. Les tests d’anticorps contre le virus de la leucémie bovine, Mycobacterium avium sous espèces paratuberculosis et Neospora caninum étaient respectivement positifs chez 37,4 %, 2,7 % et 5,7 % des vaches alors que 29,2 % des troupeaux comprenaient des animaux non vaccinés avec ≥ 1 :64 pour le virus de la diarrhée bovine virale.
