Prevalencia de parásitos gastrointestinales en bovinos de 12 a 36 meses de edad en la parroquia La Belleza, cantón Francisco de Orellana.

Abstract

The present research was aimed to prevalence of gastrointestinal parasites (GIP) in cattle from 12 to 36 months of age in old cattle in the parish from La Belleza, Francisco de Orellana canton. They were evaluated at 225 samples of bovine feces were evaluated and analyzed using two laboratory techniques (sedimentation and flotation with 0.9% saline solution). The association between the prevalence of GIP as a function of age, breed, sex, locality, and cattle raising system was determined. It was used a non-probabilistic purposive sampling, contingency tables were drawn up and the data were subjected to the Chi-square test at 95 % using the Infostat Statistical Package Infostat (IS) version 2020I; descriptive statistics were used to interpret the data. At 52.6 % of GIP was determined with the flotation technique and for the interpretation of the data, descriptive statistics were used sedimentation technique 25.4 %; eight types of GIP were identified: six of the genus Nematode (Oesophagostomum (Oesophagostomum spp, Haemonchus contortus, Trichuris spp, Cooperia spp, Ostertagia spp, Trichostrongylus spp.), a Cestode (Taenia spp.), and a Protozoan (Eimeria spp.). the highest levels of infestation were by Haemonchus contortus. It was possible to find a greater number of parasites were found with the coprological technique (flotation), where the variables age, breed, sex and locality did not condition the prevalence of gastrointestinal parasites in cattle, with the exception the cattle husbandry system, which does condition the prevalence GIP. It is recommended to carry out research on the prevalence GIP by adding new variables such as: altitude, pastures, dewormers and stocking rates, as well as evaluations to assess parasite resistance in cattle of parasites to the dewormers used in the area.
