Prevalencia de Neospora caninum en un hato de producción lechera en el Criadero Santa Catalina en el cantón Chambo.

Abstract

One of the main economic losses in dairy farming in Ecuador is caused by abortion and the presence of pathological diseases. Considering the problems covered by these types of productions, we have sought to study in greater depth one of the most representative causes of abortions worldwide. Neospora caninum is a protozoan that affects cattle at the reproductive level, with the canine as the definitive host. This protozoan can cause abortions until malformed calves and for the moment prevention is one of the solutions to this disease since there is no treatment. For the study of this protozoan, a kennel from the province of Chimborazo was taken as a reference, where the animals in production were analyzed, taking blood samples from each animal and analyzing it by means of the INDIRECT ELISA test, studying the prevalence of Neospora caninum, and in relation to variables such as age, race and clinical signs, the significance was determined by applying chi-square and analyzing the correlation that existed between the variables, with results of the analyzes performed on the 36 producing cows of the hatchery obtained a 27.78% prevalence has a total number of 10 cases positive to Neospora. Finding a statistical significance in the presence of parasites in the area where canines coexist and that the disease influences herd productive performance.
