Among the causes of productivity losses in swine productivity, the presence of gastrointestinal parasites is noteworthy. In order to design an effective control program for this problem, information is needed on the occurrence of parasite species in the locations concerned. For this reason, the aim of this study was to evaluate the occurrence of gastrointestinal parasites of pigs in non-technified productions in the Metropolitan Region of Curitiba. Fecal samples from 280 pigs from 192 farms were analysed. For the analysis, the qualitative test of spontaneous sedimentation and the count of eggs per gram of feces in the McMaster chamber were performed. Furthermore, those responsible for the farms were asked about the use of anthelmintics and the cleaning and hygiene of the facilities. Overall, 91.1% of the samples tested were positive; the most common parasite forms were strongyle eggs (66.8%), followed by Ascaris suum eggs (47.1%) and coccidia oocysts (46.1%); Balantidium coli cysts (16.8%), Trichuris suis eggs (7.1%) and Strongyloides sp. eggs (1.1%) were also present. The average total number of eggs, oocysts, or cysts per gram of feces was 1009.2±1078.8 with a range from 25 to 12,175. Regarding the questions asked to breeders, 93.2% said they provided antiparasitic to the pigs, 44.8% removed waste daily and only 13.3% said they washed and disinfected the facilities. It is concluded that the occurrence of gastrointestinal parasites is high in pigs from farms in the metropolitan region of Curitiba and that both helminths and protozoa affect these animals.Downloads
