During the months of October and November 2019, a study was carried out in the Mantaro Valley and in the Parasitology Laboratory of the Faculty of Zootechnics, of the National Agrarian University of La Molina, in order to determine the efficacy of Triclabendazole (TCBZ), Rafoxanide (RFN) + albendazole and Clorsulon (CLN) + ivermectin, the control of Fasciola hepatica. 55 Brown Swiss cattle under semi-extensive rearing, naturally infected with fasciolosis, were used between cows and heifers. Animals were divided into three experimental groups. The doses used were of TCBZ: 12mg / kg (n = 18), RFN + Albendazole: 10mg / kg + 9mg/kg, respectively (n = 18) and CLN + Ivermectin: 2mg / kg + 0.2 mg/kg, respectively (n = 19). Stool samples were collected directly from the rectum, on the day of treatment (day 0), at 15 and 30 days post treatment. The samples were analyzed using the modified Flukefinder® technique to determine the amount of eggs per gram of feces (hpg). Efficacy was determined by applying the Egg Count Reduction Test (FECRT). 95 percent confidence intervals were determined following the guidelines of the World Association for the Advancement of Veterinary Parasitology (WAAVP). The efficacy results for TCBZ, at 15 and 30 days post treatment was null in both cases, while for RFN and CLN they were 92% (95% CI = 80:99), 97% (95% CI = 94:99) and 99% (95% CI = 97:100), 80% (95% CI = 46:99) of efficacy, respectively. Statistical differences were found between hpg (RFN and CLN) before treatment and post-treatment, while the hpg of days 15 and 30 post-treatment the opposite was obtained. It is concluded that there is therapeutic failure with the TCBZ, while the last two active ingredients evaluated have good efficacy in the control of Fasciola hepatica in cattle from the farm evaluated, however, due to greater efficacy, the use of RFN is recommended for the control of Fasciola hepatica in cattle due to its better reduction percentage after 30 days.
