Models represent the understanding of a biological, production, and/or economic concept. Models can be represented simply with diagrams or a series of mathematical equations. Clearly, the objectives of the modeling experience vary dramatically and ultimately control the impact of the exercise. All models and modeling exercises described in this chapter are based (in some part) on the understanding of biological processes involved in pig production and how the description of biology is applied to swine production (Figure 38.1). It is not surprising that significant discussions have been generated, and will continue to be generated, regarding the “level of science” required to describe adequately growth, pregnancy, and lactation in the pig. The objective of this chapter is to explain some of the quantitative methods used to describe biological and nutritional impacts on swine production. For more-detailed discussions of biological modeling, the reader is encouraged to consult the following references: France and Thornley (1984), Whittemore (1986), Baldwin (1995), and Black (1995).
