Résumé:
The aim of this work was demonstrate the elimination of infective forms of L4
larvae of S. papillosus in milk and colostrum of cows from properties in Paraíba semiarid
region. This nematode is kown as responsible for high incidence of parasitic enteritis in
calves, primarily in the first weeks of life. The samples were collected in five cities located
in semiarid Paraíba: Catingueira, Emas, Patos, Sousa and Vieirópolis. The animals had no
management changes during the experiment. In a first stage, eighty samples were collected
randomly from cows in any lactation stage. The second stage consisted in collecting
seventy five milk and/or colostrum samples from cows that were first to seven day calved.
All samples were sent to the Laboratório de Parasitologia Veterinária da Universidade
Federal de Campina Grande – Campus Patos-PB, where the samples were analyzed to
determine the presence of fourth stage larvae of S. papillosus. The results showed that in
100% of the milk samples analyzed could be detected the presence of the nematode, while
in the colostrums samples, the elimination occurs in an irregular and reduced form. Based
on the results obtained, concludes that transmamary elimination is an important way of
infection to newborn calves.
