Prevalencia de parásitos gastrointestinales en cerdos en el cantón Saraguro de la provincia de Loja, Ecuador.

Abstract

In Ecuador, one of the most carried out livestock activities is the swine production, especially in the Saraguro canton, with three types or systems of extensive, semi-extensive and intensive exploitation. To determinate the prevalence of gastrointestinal parasites in pigs in the Saraguro canton, a sampling was done in 85 farms where 297 stool samples were taken, which were analyzed by qualitative and quantitative techniques. 71.5% of the general prevalence of gastrointestinal parasites was obtained. The parasites found were Balantidium coli (85,8%), Ascaris suum (48,1%), Hyostrongylus rubidus/Oesophagostomum dentatum (35,6%), Strongyloides ransomi (27,9%) and with lower prevalence Macracanthorhynchus hirudinaceus (1%); using the McMaster technique it was established that pigs under one year of age have a moderate degree of infection. In stool samples technique was found with two types of parasites Hyostrongylus rubidus/Oesophagostomum dentatum which were more representative in male pigs under one year. In addition, it was established that the age and sex of the animals influences the type of parasites found.
