Dictyocaulus - D. Arnfieldi in Horses and Donkeys

D. Arnfieldi in Horses and Donkeys

D. arnfieldi is similar to D. viviparus in cattle, but only affects equids. Donkeys usually show no disease and can be silent carriers (and shedders) of this parasite, which causes clinical signs in horses. Routine deworming of horses and donkeys may help prevent cross infection when kept together. Pastures that housed donkeys may be infected with lungworm larvae. As a result, horses and donkeys should not be grazed together. These drugs are given with three weeks intervals between treatments.
