Implementation and evaluation of a strategic parasite control program for captive exotic ungulates.

A parasite control program was designed for greater than 1,200 exotic ungulates maintained in mixed-species enclosures at the San Diego Wild Animal Park. Three strategically-timed anthelmintic treatments were given during 1988-1989, and their success was evaluated by monitoring pretreatment and posttreatment fecal egg counts. Adequate parasite control was achieved for animals in 52 ungulate species, as evidenced by low pretreatment egg counts and the absence of egg-shedding after treatment. However, animals belonging to 11 species in the subfamilies Antilopinae, Hippotraginae, and Caprinae were identified as important targets for more intensive control efforts because they shed either greater than 100 eggs/g of feces before treatment, or greater than 0 eggs/g after treatment, at 2 or more sampling periods. These results and observations were used to generate management recommendations and illustrate how a model parasite control program can be developed for collections of exotic ungulates.
