Perhaps one of the biggest challenges when managing parasites in donkeys is that of clinical assessment. Donkeys with significant endoparasite burdens may appear healthy and it is rare to observe the type of clinical signs (diarrhoea, weight loss, colic or poor condition) that are more common in horses and ponies.
Although donkeys can be infected by the same parasites as horses and ponies there are some notable differences in parasite dynamics and treatment regimes, the most important being the lack of anthelmintic products licensed for use in donkeys.
