Parasites that utilize a specific intermediate host cannot reproduce in areas that do not support an appropriate intermediate host. In some cases, wildlife can carry parasites of domestic animals either as a direct carrier or as an intermediate host. If domestic animals are exposed to such carriers or their feces, the possiblity of parasite transmission exists. Feedstuffs can be contaminated with infective stages of several parasites. Feeds contaminated by human waste via fertilization of hay fields or direct contamination of feed supplies can transmit parasite eggs.
Wildlife frequently make nests in buildings in hay lofts or among sacks of grain.
Fecal contamination by that wildlife can be a source of parasite infections. There are several different methods of raising animals for profit or pleasure, most of which can be translated from one species to another with only a few modifications. The basic principles and particular methods used to raise the different animal species are discussed on another page. Animals in a drylot are frequently kept at a concentration which precludes growth of new vegetation. These animals will require daily feeding of a total balanced ration.
