Eficacia de la combinación entre Ivermectina y Fipronil como desparasitante externo en Cavia porcellus, en el barrio San Agustín, cantón Puyango, provincia de Loja.

Abstract

The objective of this research was to evaluate the efficacy of the combination of Ivermectin and Fipronil as external dewormers in guinea pigs; the study was experimental, with a quantitative and descriptive approach; the population consisted of 87 guinea pigs from the San Agustin neighborhood, which were checked for skin and fur, condition, body and skin scraping and imprinting, whose tests were taken to the laboratory to analyze if they had ectoparasites. Then, the combination of Ivermectin and Fipronil was applied to all the animals, and an analysis was made by imprinting on days 7 and 14 to observe if the drugs applied were effective or not to combat the ectoparasites, which had a high presence of mites and a low presence of lice. Finally, the Chi-square test was applied to these data, resulting in a p < 0.05, which means that the relative hypothesis was accepted, which indicates that the administration of the combination of these chemical dewormers totally or significantly reduces the presence of ectoparasites; at the same time, it was concluded that this combination of drugs does not show secondary effects in guinea pigs.
