    Prevalencia de Fasciola hepática en bovinos faenados en el Camal municipal del Cantón Pelileo Provincia de Tungurahua en el período Marzo-Mayo del 2024
    (2024-11) Carranza Arévalo Álvaro Iván; Almeida Secaira Roberto Ismael
    Fasciolosis is a zoonotic disease caused by Fasciola hepatica, which is considered a tropical disease that threatens the productivity of ruminants due to the economic losses associated with the presence of the parasite. The prevalence of Fasciola hepatica in cattle slaughtered at the municipal slaughterhouse of the Pelileo Canton, Tungurahua Province, was evaluated in the period March-May 2024. The study was carried out through macroscopic observation of livers obtained from cattle slaughtered at the slaughterhouse and the possible association between the sex and origin of the animal on the predisposition to the presence of the parasite was evaluated using a Pearson association test (𝜒2). From a total of 1,622 animals sampled, the overall prevalence of Fasciola hepatica in the dataset was found to be 8.08%, which corresponds to 131 animals that presented symptoms of the disease. In relation to the place of origin, the highest prevalence was observed in cattle from Salcedo, Chiquicha parish, Ambato and El Rosario with values of 9.9%, 9.8%, 9.7% and 9.6%, respectively, which are considered moderate values, while in Bolívar, the prevalence was the lowest (4.5%). No association was found between sex and prevalence, with percentages of 43.9% in males and 45.3% in females (𝜒2=0.243). The total value in liver losses, considering the price per kilo and the number of positive animals for each group was $2,728.00 during the study period, making a ratio of 100% of slaughtered livers (1,622 units), a loss of 8.08% due to confiscations is obtained. Given the prevalence of the parasite in livestock in the production areas of the Sierra zone, the development and implementation of training programs for small and medium producers on the management of F. hepatica in their production units is recommended.
