Avaliação parasitária, hematológica e manejo produtivo de suínos nativos da Baixada Maranhense

Abstract

The Baixada Maranhense is region in Maranhão state, in Brazil, located in northwest of the state. Native swine is originating this region and live an extensive system. The aim of this study was to identify swine native helminth fauna and their interference in haematological tests, beyond the form of raising pigs in this region. A total of 200 feces samples for fecal examinations and 80 blood samples for haematological tests were collected during periods of drought, rain and interim periods. Weather data for comparison with the parasite load were obtained. Data about management of the animals were obtained by a questionnaire. It was detected eggs of the Superfamily Strongyloidea and genders / species of Strongyloides, Trichuris suis, Ascaris suum, Metastrongylus eggs and larvae, oocysts of coccidia, cysts of Balantidium coli and Entamoeba coli, and Acanthocephalo Macracanthorhynchus hirudinaceus. The parasite load did not affect haematological variables and climate only interfered in OPG of Bacurituba. The management is extensive without technology, using what environment offers. It is concluded that the native pigs at Baixada Maranhense are rustic animals living with internal parasites without affecting their health condition.
