HAMMERSCHMIDT, J. et al. Evaluation of the integrated parasite control in a semi-intensive goat farming in the region of Santa Catarina. Arq. Bras. Med. Vet. Zootec. [online]. 2012, vol.64, n.4, pp.927-934. ISSN 1678-4162. http://dx.doi.org/10.1590/S0102-09352012000400020.
The objective of this study was to subsidize a sustainable parasite control program in a flock of goats in São Francisco do Sul, SC, Brazil, applying the integrated system for parasite control. Sixty three adult animals were used in nine groups to perform an anthelmintic efficacy test, faecal egg count (FEC), Famacha method, haematocrit, body condition score, coproculture, and the presence of larvae on pasture. Drug efficacy measured by FEC 15 days post-treatment with closantel, ivermectin + Levamisole + albendazole, albendazole, nitroxinyl, levamisol, abamectin, ivermectin, moxidectin and albendazole was 85, 57, 83, 65, 63, 31, 28, 24 and 0%, respectively. The Famacha score 1 or 2 was given to 81% and scores 3, 4 or 5 were given to 19%, without significant correlation with haematocrit values since the predominant was Trichostrongylus sp. (92%). The count of infective larvae levels on pasture revealed values below 1000 L3/kg/DM predominantly Trichostrongylus sp. None of the tested drugs was effective, showing multiple parasitic resistance. The correct application of the SICOPA and adoption of management strategies and proper nutrition are essential to establish a sustainable health program.
