Sistema de apoio na escolha de reprodutores de bovinos de corte avaliados em programas de melhoramento

Abstract

The Brazilian cattle production system is characterized by an extensive way of exploitation which emphasis the low genetic potential, resulting in incomplete utilization of resources and low productivity. The conduction of selection in beef cattle populations, through the use of harmonious sires ensures participation in the global market and profitability to production systems. The breeding programs have several options for sires in each race and with many evaluated characteristics. This paper aimed to create a tool, using a logical model, to facilitating and assistance in the sire choice, from a bulls summary based on the characteristics desired by the user. The model was developed and implemented on the basis of data management through the PostgreSQL (PostgreSQL, 2009) and the PHP programming language that is the basis web development (PHP community, 2009). The incoming data are breed, progeny differences, weaning, yearling, ultrasound, DECAs and accuracies. According to verification tests, the model considers requirements pre-established and launched by user where the list of sires is processed and presented in a restrictive way, facilitating the decision
