PRESENCE OF PARASITES OF THE ORDER STRONGYLIDA IN DAIRY CATTLES RAISED ON PASTURE AND IN THE COMPOST BARN SYSTEM IN THE FREDERICO WESTPHALEN MICROREGION

Abstract

The constant presence of endoparasites in dairy herds has affected both the productivity and welfare of the animals. Consequently, the use of fecal exams has become crucial for veterinarians and property owners, as the results obtained allow for the adoption of appropriate control and prevention measures. There is a shortage of studies linking farming systems to the level of parasitism in cattle. In this study, 12 properties in the microregion of Frederico Westphalen - RS were visited, with 6 using extensive pasture systems and the other 6 employing intensive systems (compost barns). Through fecal analysis on these properties, it was found, as expected, that animals in pasture systems are more susceptible to helminth infections. Both intensive and extensive systems in dairy farming showed endoparasitosis, indicating that even cattle raised under intensive management are exposed to gastrointestinal parasites. It is concluded that in intensive systems such as compost barns, producers have greater control over potential herd parasitism, although this does not eliminate the possibility of infections occurring in the animals.
