Beef cattle is a product of great importance for the economy of countries like Brazil, nowadays the most important producer and exporter country of beef cattle in the world. However, to maintain itself on this important economic position, Brazil needs constantly to improve its production systems as well to invest in aspects related to sanitary control, according to the requirements of the consuming market like the European Community. The goal of OTAG project is to provide conditions to know the relative risks concerning to the bovine traceability, in the context of Southern Cone Countries and the EU policies. The project is based on the existing knowledge in Europe and Canada concerning to information systems and geo-decisional tools, as well to the interaction among experts and user groups from South Cone, Canada and Europe. OTAG prototype conceives the use of electronic devices for measuring the animal geo-localization in the herd. This information is associated to data about farm management, such as feeding and production systems in use. This paper presents the characteristics, tools and steps concerned to the development of the OTAG information system, aiming to obtain a prototype to analyse the beef cattle traceability under experimental conditions in Campo Grande, Brazil.
