EFICÁCIA ANTI-HELMÍNTICA DO ALBENDAZOLE E LEVAMISOL UTILIZADOS ISOLADAMENTE E EM ASSOCIAÇÃO EM OVINOS DA MICRORREGIÃO DO BREJO PARAÍBANO.

Abstract

The sheep breeding has emerged as Important economic activity, characterized as one of the main sectors for exploration and growth for the development of activity in Brazil. However, one of the main cumber the growth of this segment are the parasitosis by gastrointestinal nematodes. Different schemes of parasite treatments are used, but most of the time, they are not properly adopted, and the parasites develop anthelmintic resistance. Thus, in order to analyze the efficacy of anthelmintic albendazole and levamizol, these were tested individually and in combination in sheep raised semi- intensively, in the micro-region of Brejo Paraibano in the city Areia. Project participated 28 animals naturally infected with larvae of nematodes, regardless of gender, aged 2 months for 3 years, which have been identified and randomized into three groups. Group 1 was treated with albendazole, levamisole with 2 and 3 with both Association. Stool samples from each animal were collected in pre and post- worming to perform the count OPG and determining the effectiveness of the principles used. It was considered effective suspected effective and ineffective results >90%, between 80% and 90% and <80 % respectively, and means for comparing the OPG group, we used the test of variance analysis and Tukey 5%. It was proven resistance to drugs, when given alone, however, the treatment using the combination of these was efficient (100%) , however this should not be the only method of control of helminths.
