Custo da implantação e utilização de dois métodos de identificação de bovinos leiteiros

Abstract

This study aimed to evaluate the cost of the implantation of two methods of cattle identification, namely conventional earring and electronic ear tag, in addition to discussing both the advantages and limitations of each of them. All the operational expenses concerning to the identification were recorded and, for each method, the times of holding of the animal, the implantation of the identifier, the earring reading, typing and data transfer were surveyed. The cost of the identification by using the electronic tag was the highest, mainly the purchase of the equipment and identification device. Nevertheless, there was increased reliability of the recorded information, since the conventional earring in spite of having lower cost, induced errors in data transcription. Therefore, it is up to the farmers to decide which method should be suitable for their production system, taking into account not only financial issues but also the limitations and benefits of each method.
