Abstract

This study aimed to evaluate the activity of anthelmintic trichlorfon (Neguvon ®) and closantel (Zuletel ®) in lambs naturally infected with Haemonchus sp. Twenty-seven lambs, crossbred Ile of France with Corridale, 90 days-old, were divided into 3 groups of nine animals: Group 1, animals were treated with trichlorfon (Neguvon ®) orally at a dose of 97 mg.kg-1 body weight, Group 2 were treated with closantel (Zuletel ®) at a dose of 10 mg .kg-1 body weight and Group 3 did not receive any kind of anthelmintic treatment. Through the test of reduction of OPG could be noted that the trichlorfon showed effectiveness of 97.9% and 55.2% closantel. It is noted the first closantel resistance in lambs in the central area of the state of Parana, Brazil.
