Abstract
They were appraised in the summer and winter of the year of 1991, the incidence of endoparasites in 21 pig farms of the Southwest of Paraná. In each herd were evaluated the diarrhoea in the suckling, weight variation coefficient (VC) at weaning and average daily weight gain (DWG) in the period. The samples of collected feces of the sows and her litters were appraised for the flotation method. In the period of the summer, the Coccids and Strongilids they were the parasites more frequently found in the feces of sows and her litters. In the winter period, the larger occurrence was of Coccids, so much in sows as her litters. DWG and VC were respectively 38g/ day lower and 12% higher in farms where Coccids were demonstrated in piglets feces in comparison to negative farms.
