Abstract

The parasitism of swine by nematoid Ascaris suum mainly occurs in the early stages of creating the animals, when the parasite makes migration hepato tracheal in those animals and can even cause death of young animals. This nematode is considered the main cause of production loss in swine farms. Given the importance of parasitism by A. suum, it is recommended as ideal conditions identify the agent in the animals the most previously possible. One of the most practical ways to make the diagnosis of this nematode would be the verification of the presence of milky white spots (spot milk) on the surface of swine livers inspected at slaughter resulting from larval migration in that organ. Also, this nematode is the leading cause of condemnation of livers at slaughter inspection. This study aims to assess the level of A. suum infection in pigs at the age of slaughter created in technified farms located in three municipalities in the Zona da Mata region. This study was conducted in three slaughterhouses located in municipality of Piranga and consisting of assess the level of observed alterations in the livers of slaughtered animals. These lesions that were observed showed it as suspicions of parasitism by A. suum in those animals, at least, at some stage of life of these. It should be remembered that some situations as low parasite load, constant cleaning of the stalls and periodic deworming of animals are responsible for many of the animals parasitized by A. suum not reached adulthood or has delayed its development, being present in animals in the larval stage L3 (liver) and L4 and L5 (the lungs). By fact of this agent to be responsible for significant losses in pig farming, it is recommended that these swine farms conduct a strategic protocol of deworming in piglets and matrixes
