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.

Pork continues to occupy an important position as a food source in affluent societies as well as in developing countries with slower economic growth. The growth of the world swine population continues at a faster rate than that of the human population, a reflection of the sustained demand for pork in all parts of the world. The technical basis for commercial production of swine was presented in our two earlier textbooks-Swine Production in Temperate and Tropical Environ ments, by Pond and Maner, 1974, and Swine Production and Nutrition, by Pond and Maner, 1984. In view of rapidly advancing technology and an appreciation for the systems approach in industry and agriculture, this third book has been restructured to provide the student and practitioner with an integrated concept of pork production. We have attempted to blend the fundamental principles from genetics, physiology, nutrition, and biotechnology into the modern concepts of systems analysis and simulation modeling. The objective is to create a teaching approach which empha sizes the integrated synthesis of biological with physical and environmental sci ences and economics. This approach is expected to provide an overall pork pro duction systems view that individual producers can adapt to their specific resources, needs, and goals. Our new co-author, Dr. Dewey Harris, has used his expertise and perspective on interacting systems to change the complexion of the book to fulfill this objective. In addition, Dr.

With 42 chapters authored by leading international experts, Swine Nutrition: Second Edition is a comprehensive reference that covers all aspects of the nutrition of pigs. Content includes characteristics of swine and the swine industry with emphasis on the gastrointestinal tract; various classes of nutrients, how these nutrients are metabolized by swine, and the factors affecting their utilization; the practical aspects of swine nutrition from birth through gestation, lactation in sows, and the feeding of adult boars; and nutritional aspects of the various feedstuffs commonly fed to swine. Rounding the book is coverage of various techniques used in swine nutrition research.
