The cost-effectiveness of raising pigs primarily depends on the health of the farmed animals. Swine diseases pose a significant economic problem throughout the world, with losses from parasitic diseases being substantial compared to those caused by bacterial and viral infections. Parasites precede bacterial and viral diseases, exacerbated by the deteriorating condition of pigs. Parasitic infections cause significant economic losses on swine farms by decreased production and reproduction, and also by augmented morbidity and mortality. The vast majority of swine in Romania, are raised on low input farms, the number of which has been registered as increasing in the last decades. Organic farming depends on the ecological factors focusing on environment protection, plant health, animal health, food safety, and consumer health. The free-range raising system is a type of farming where the animals, for at least part of the day, can roam freely outdoors rather than being confined in an enclosure for 24 h each day. The current study aimed at identifying the parasitic profile of swine raised on two free-range farms in Transylvania included in three age categories. Romania has a temperate-continental climate of transitional type, with four clearly defined seasons, therefore systematic sampling over a year would also allow the investigation of possible seasonal trends of the identified parasitic infections. The samples were collected from two free-range farms, both raising Mangalitza and Bazna local swine breeds. The farms were located in Nord-West Region of Romania, a hilly area defined by abundant pastures, forests and specific temperate-continental climate. Drinking water for the animals was provided from a local fresh water source. The shelters were periodically cleaned throughout the year. The animals had access to outdoor areas at all times. A total of 960 fecal samples from the two farms were collected and examined during the experiment. Collected samples were examined by centrifugal sedimentation, flotation—Willis method, fecal smear stained by modified Ziehl-Neelsen technique, Blagg method, McMaster egg counting technique, and fecal cultures. The coproparasitological examination revealed co-infections with several species of parasites, respectively, Eimeria spp., Balantidium coli, Ascaris suum, Trichuris suis, Oesophagostomum spp., Strongyloides ransomi and Cryptosporidium spp. This study provides essential information on Transylvania’s distribution of gastrointestinal parasites in pigs. It was demonstrated that different species of gastrointestinal parasites are present in most pigs reared in free-range farms in the study area. The current information has great value to farmers, policy makers, and researchers alike, that should contribute to safer and healthier pork production for public consumption. Specifically, control strategies are needed to raise awareness among pig farmers about the negative impact of these parasites on the productivity and health of pigs and, in some cases, on human health (certain pig parasites are zoonotic).
