Estudo da eficiência da atividade anti-helmíntica de ivermectina e moxidectina em ovinos localizados em Feira de Santana, São Gonçalo dos Campos e Castro Alves

Abstract

The importance of sheep farming to Brazil is revealed by its position as the 16th largest producer of sheep in the world, however this production still does not meetthe national demand for sheep meat. One of the main limiting factors of productivity in this sector is gastrointestinal parasites. These high rates of infection of the herds determine economic losses in the production of the small ruminants, either by direct losses to the production with the fall of the performance in the affected animals as of indirect way in the use of medicines for the control of the primary and secondary diseases. The use of drugs with low efficiency causes economic losses, since the investment does not generate a desired therapeutic effect, animal welfare and / or productivity. The objective of this work was to evaluate the efficacy of the active principles ivermectin and moxidectin in sheep located in the following municipalities of the state of Bahia: Feira de Santana, São Gonçalo dos Campos and Castro Alves. And the multiple RA occurred two of the three properties, and MOX was not tested on a property. In the property of number 02, carried out in the municipality of Castro Alves, IVC and MOX were used, with efficiency ranging from 53.3% to 82.6%. In the property number 01, located in the municipality of São Gonçalo dos Campos the IVC and MOX presented efficiency of 18.3% and 80.5% respectively. Current parasite control measures have not achieved efficiency within the WAAVP recommended. The current parasite control measures have not achieved efficiency within the recommended by the WAAVP, which advocates the use of anthelmintics with an efficiency equal to or greater than 90%.
