Gastrointestinal parasites of pig raised on a pig farm in Nova Iguaçu, Rio de Janeiro

Abstract

At the national level, there are several types of pig breeding that employ diversified technologies and management, depending on the financial conditions of each producer. This difference, evidenced in the productions, ends up reflecting the presence of infectious agents in animals, including infections determined by gastrointestinal parasites such as helminths and protozoa. Due to the lack of information and the importance of this topic, this study aimed to report, through a parasitological survey, the frequency of gastrointestinal parasites detected in pig raised on a farm located in the Nova Iguaçú city, Rio de Janeiro. For this purpose, 200 fecal samples from 40 pens were collected. Fecal samples were processed in a pool using the Lutz spontaneous sedimentation technique. In 100% of the samples, forms of parasites were detected, being mainly strongyles eggs (97.5%), followed by coccidia oocysts (87.5%), Balantioides coli cysts (75%), Strongyloides ransomi eggs (42.5%), Ascaris suum (25%) eggs and Trichuris suis (7.5%), with statistically significant differences between these frequencies. From the parasitological survey carried out, it was possible to identify a high frequency of parasites in the fecal samples of the animals, confirming that the pig farm had recarious conditions for sanitary management.
