Abstract

Agribusiness currently plays important role in the economy of the country. Brazilian exports had a fall, even so the balance of trade is positive. Agribusiness, been suffering health pressures in order to improve the quality of their products. By owning one of the largest commercial herd in the world, there is a higher parasite burden in the herd and the mood predisposes to endo and ectoparasites causing losses in the production chain. The use of Macrociclics Lactones based products, are composed of wide spectrum, used for the endectocida control. In 2010, the beef embargo upon detection of ivermectin residues above the threshold adopted by the us. The Brazil regulates the use of anti-parasitic drugs according to the MAP, SDA, (Ordinance No. 48/97). This work was developed based on data sourced from the prohibition of the use and manufacture of LM by MAP, in order to discuss the role and importance of these drugs in the parasitic control of cattle and the impact for industries and producers resulting in the ban. Through research on what kinds of antiparasitic medicines with bases in LM marketed in Brazil at the time of the ban, along with a survey of data on parasitic control adopted in farms of Rio Grande do Sul. As a source of consultation were bulls of medicines classified as endectocides, available on the website "Compendium Vet" and on the internet, crossing the results with the list of products with existing licenses, published on the website of the MAP in April 2014. The information about the use of Macrociclics Lactones in rural properties were obtained by study of the exploratory and descriptive type. The research instrument consisted of questionnaire applied in 13 properties located in the region of the campaign. The questionnaire was drawn up as part of a research project of Embrapa Livestock South, whose main objective is to assess the risks of occurrence of ivermectin residues in beef.

The survey on site Veterinarian, Compendium on list of licensed products by MAP and products marketed on the internet, 52 companies, out of a total of 71, selling a total of 146 endectocides products identified in sources of information researched .48 with grace period exceeding 42 days, 82 with 35 days of grace period for slaughter, in 16 products not found the grace period information for slaughter. The results of the application of the questionnaire were divided into two parts, the characterization of the properties and for health management. Properties with average size of 1953 ha and cutting cattle as main activity. Most used British breeds. The level of education of the administrators was another highlight, with 92% having higher grade, among veterinarians, agronomists, administrators and zootechnists. Health management was rated according to the degree of knowledge of the administrators of the property. The main variables addressed, parasites treatment target, relevance of parasitism by the tick, loss of animals by TPB, knowledge of the grace period of the products it uses, knowledge about the normative Instruction 48.
