Prevalencia de nematodos gastrointestinales en ovinos productores de carne en tres predios de la costa ecuatorial.

Abstract

Gastrointestinal parasitosis affecting cattle destined for meat production cause significant decreases in their performance, reducing the producer's economic income. Since this is a generalized problem due to inadequate technical and sanitary management of herds, it was proposed to investigate which parasites are prevalent on the Ecuadorian coast, allowing the identification of the specific treatment to be recommended. Therefore, this field study, with a nonexperimental, descriptive and correlational design, was carried out in 3 farms of the equatorial coast, where the objective was to determine the prevalence of gastrointestinal nematodes that affect sheep meat producers. A total of 100 sheep were floated for gastrointestinal nematode dispersal forms, distributed in 40 animals from the first and second farm respectively; 20 animals from the third farm, taken completely at random, analyzing feeding and sanitary management as risk factors and age and sex to determine predisposition to gastrointestinal nematodiasis. The results obtained were finally correlated with the variables sex, age and management of the farm, finding a prevalence of 75% which corresponds to the presence of Ostertagia and Trichuris, finding that the animals with greater presence of parasitosis corresponds to the free grazing farms, and that in terms of age, the highest frequency of parasites was given in animals from one to three years of age, this agrees with the results found in the results.
