Pathology in practice - Fascioliasis in a Dahl sheep
Journal of the American Veterinary Medicine Association
In early fall 2012, a 48-kg (106-lb) sexually intact male Dahl ram in fair body condition was found dead; the owner observed no clinical signs prior to death. The ram was part of a ﬂock of 50 game animals used for high-fence hunting that was moved among pastures in Idaho, Utah, and Montana. The ram was housed primarily on ﬂood-irrigated pasture in common with approximately 170 captive Rocky Mountain elk (Cervus canadensis). The owner reported that 12 other sheep had died over the past year without observed clinical signs, but none were submitted for postmortem examination. Both sheep and elk were orally dewormed each February with 11.3% albendazole at a dose of 10 mg/kg (4.5 mg/lb; labeled cattle dose).
