Herd Health for Donkeys

INTESTINAL AND LUNGWORM PARASITE CONTROL Intestinal parasites affecting donkeys are similar to those that affect horses. These include nematodes (large and small strongyles, ascarids, pinworms), bots, and Cestodes (tapeworms). Basic principles of parasite control are the same as for larger equines. Medications used with success in donkeys include fenbendazole, ivermectin, albendazole, and pyrantel pamoate. Lungworms. Animals in certain areas of the country are also affected by lungworms. These areas are not well defined. Donkeys are the natural hosts for lungworms and as such do not show obvious signs of disease when infected. In fact, the incidence of donkey infestation is not known. Mules are reported to be relatively unaffected by lungworm infestation, much like donkeys. Horses, however, may be severely affected, exhibiting coughing and wheezing. Lungworms should be suspected if an affected horse is pastured with donkeys or mules. Definitive diagnosis is made by demonstrating the presence of Dictyocaulis arnfeldi larvae in fresh feces. Treatment is achieved by oral dosing with ivermectin, followed by a repeat treatment in three weeks. Other strategies of parasite control include pasture rotation, removal of manure, and deworming of new herd additions. Successful use or need for deworming medications should be measured by periodic fecal examinations. I recommend the sugar centrifugation technique of fecal analysis.
