The parasitological diagnostic was made by four coproparasitic methods: direct, flotation, sedimentation and Baermann. For the egg count, was used the McMaster method. There was a 64.4% prevalence of gastrointestinal parasites per individual and 82.9% prevalence per farm of gastrointestinal parasites, being Ascaris suum the most prevalent parasite, followed by Strongyloides ransomi and last the Balantidium coli. Was determinate the grade of infection (HPG) which shows that 58,69% of the individuals presented a high or massive infection. Being Catacoha the parish with the highest prevalence and infection of gastrointestinal parasites. In order to determine the risk factors, all the variables of the producer’s survey were analyzed and was established that the only factor that contributed to the canton is the absence of internal deworming of the adult animals (OR = 95% CI = 1,009-2,642).
