The aim of this study was to comparative of two therapies pharmacological based ivermectin and febendazole by Strongyles control intestinal in Thoroughbreds horses. Were study 110 horses all of 2 years old (55 Stallion and 55 Mares), in the Racetrack “La Rinconada” Caracas-Venezuela. A stool test was performed prior to treatment to each horse. Group 1: 50 horses were evaluated before treatment, using a stool test, then was given Ivermectin (0.2 mg/kg) 1% 7 ml, with reassessment intramuscularly coprological at 7 days. Group 2: 50 horses were evaluated before treatment, using a stool test, Fenbendazole was later administered (5 mg/kg) 18.8% oral paste 12 g. With reassessment coprological at 7 days. Group 3: 10 equines those not administered drug therapy, alone parasite burden was assessed using a fecal examination by Willis test. Anthelmintics effectiveness was conducted by counting fecal drug-treated group and the untreated control group. The results Group1 with Ivermectin 2.38 EPG showed pre-treatment and post treatment 7 days EPG 0.48. The group2 with Fenbendazole obtained 2.66 EPG and 7 days post treatment was obtained 0.06 EPG. Group 3 without medication present the following day 1.9 EPG value and then at 7 days 2 EPG. Comparing the effectiveness of both drug treatment and fenbendazole ivermectin antiparasitic indicate that fenbendazole base is more effective against the equine intestinal Strongylus, taking a percentage of 97% in comparison with specifically macrocyclic lactones which Ivermectin obtained a much lower drug efficacy throwing only 76%.
