Evaluación comparativa de dos métodos de diagnóstico parasitario de campo ( famacha) y de laboratorio (mc master), en ovinos de la comunidad el socorro, Riobamba.

Abstract

The investigation was carried out in El Socorro Community, Cubijíes parish in Riobamba Canton, to evaluate two parasitic diagnostic methods, FAMACHA and McMaster.The experimental units were 14 sheep of the Corriedale breed and 6 mestizo sheep, in which, when applying FAMACHA, the ocular conjunctive color was observed and at the same time stool samples were taken to analyze them in the Microbiology Laboratory of the Faculty of Animal Sciences to determine the parasitic loads expressed in eggs per gram (EPG). The evaluation of the two post-treatment methods was performed three consecutive times every fifteen days. Having an initial parasitic load of 5811.5 EPG while at 15, 30 and 45 days it was 785; 107.5 and 617.5 EPG respectively, reaching an efficiency of the antihelminticLevamisol of 92.14%, 97.68 and 86.25% at 15, 30 and 45 days after application. When submitting the results to Pearson's linear correlation, it was found that there is a correlation of 70% between the two techniques used to determine the parasitic load of sheep. This means that for the parasitic diagnosis in sheep, the FAMACHA field technique can be used in places where there is no access to specialized laboratories having a high correlation with the McMaster technique.
