Modeling as a research tool in poultry science

The World's Poultry Science Association (WPSA) is a long-established and unique organization that strives to advance knowledge and understanding of all aspects of poultry science and the poultry industry. Its 3 main aims are education, organization, and research. The WPSA Keynote Lecture, titled "Modeling as a research tool in poultry science," addresses 2 of these aims, namely, the value of modeling in research and education. The role of scientists is to put forward and then to test theories. These theories, or models, at improving our understanding of a system or the interaction between systems. In developing a model, the scientist must take into account existing knowledge, and in this process gaps in our knowledge of a system are identified. useful ideas for research are generated in this way, and experiments may be designed specifically to address these issues. The resultant models become more accurate and more useful, and can be used in education and extension as a means of explaining many of the complex issues that arise in poultry science.
