Abstract

The objective of the study was to estimate the prevalence of gastrointestinal parasites in pigs from Quilanga town, sampling was carried out in 56 farms with a total of 238 samples of individuals, which were analyzed by qualitative methods (direct, flotation and sedimentation) and quantitative (McMaster and stool culture). A general gastrointestinal parasite prevalence of 78.2% was obtained. In the direct method and by sedimentation, 31.4% and 28.4% respectively, the most found parasite was Balantidium coli and, less frequently, Eimera debliecki with 0.8% and 0.4%; in the flotation method with 29.7% the parasite with the highest prevalence was Strongyloides ransomi and with less presence Macracanthorhynchus hirudinaceus. The intensity of infection (hpg) was determined in the positive samples with the flotation method, obtaining a high degree of infection (86.1%) in young animals. In the stool cultures Hyostrongylus rubidus was found in 17 samples and Oesophagostomum dentatum in 3 samples. In the epidemiological study, good management practices were identified as protective factors and, statistically, no risk factors were established.
