A simulation model was developed to predict body weight and carcass composition in growing swine. The model is subdivided into modules,each responsible for simulating one portion of the model, such that the modules are as independent of each other as possible. Four modules are defined for simulating the microenvironment surrounding the pig, the feeding program used, the pig's heat balance and its metabolism. Fundamental concepts used in the model include a pool of readily available nutrients, speration of lean and fat tissue deposition, and the use of body temperature as a measurement of the thermal environment. The model predicts weight gain, feed consumption, carcass composition, heat production and body temperature. A graphical user interface program was developed to implement the model in a personal computer environment. Theuser can set the parameters for the simulation and observe the results in 15 different types of graphs. An expert system is interfaced with the simulation model to analyze the production system based on the simulation results. After the simulation model runs, the expert system iscalled and the resulting output is displayed on the screen. The model was calibrated and validated against experimental results, and responds to changes in environmental and nutritional factors in a manner similar to the way a real pig would. Although more research is needed to determine all the model parameters for modern pigs, the model provides a frame onto which the results of such research can be readily incorporated. The expert system interface provides an additional tool for management of swine production systems not found in other simulation models and is flexible enough to easily accept the incorporation of new knowledje as it becomes available.
