Abstract
O desempenho eficiente da produção de suínos depende da gestão do rebanho, bem como da nutrição, do controle sanitário, das instalações e de condições ambientais adequadas. O conceito desse tipo de produção está diretamente relacionado com a redução das perdas seletivas e o controle do processo. Cada segmento da produção é controlado de maneira a alcançar a otimização na totalidade do sistema, ou seja, é necessário aplicar conceitos de manejo dos animais. Sendo assim, o presente trabalho apresenta como objetivo o desenvolvimento de modelo matemático para avaliar as interações do ambiente interno da instalação com a preferência térmica dos animais, detectando relação entre a freqüência de acesso ao bebedouro e as condições do ambiente, temperatura ambiente, temperatura de globo negro e umidade relativa, utilizando como ferramenta a identificação eletrônica. Os resultados obtidos por meio do modelo matemático permitiram concluir com precisão a avaliação da preferência térmica dos suínos em relação às variáveis climáticas na fase de gestação.
The efficiency of swine production performance depends on the herd administration, such as good nutrition, sanitary control, facilities and appropriate environmental conditions. The concept of this production model is directly related with the reduction of selective losses and the process control. Each production segment is controlled to reach the optimization in the system totality, it is necessary to apply animals handling concepts, environmental control implementation, diseases control, nutrition control, information concerning in guaranteeing the animal welfare and individual identification. The present work presents as objective the development of the mathematical model to evaluate interactions among the internal atmosphere of the installation and the thermal animals preference, in the expectation of detecting a relationship among the frequency access to the drinking fountain and the atmosphere conditions - temperature, black globe temperature and relative humidity, using as tool the electronic identification. The results obtained by the mathematical model, allowed to conclude accurately the evaluation of the swine thermal preference correlating with the climatic variables in the pregnancy stage.
