通过将营养物质利用和动物环境相互作用的知识整合到一个系统中，猪生长模型可以成为确定个体生长-肥育猪单位最佳管理策略的有用工具。此外，这些模型可用于展示猪生长中营养利用的基本原理，检查“假设”情景，帮助制定猪育种计划和制定有效的研究计划。商业猪肉生产中使用的模型应该代表猪的生长生物学，应该是灵活的，这样它们就可以很容易地集中在特定生长肥育猪单位的需求和特殊条件上。为了使生猪生长模型在实际中得到合理的应用，必须对生猪单位进行合理准确的表征。这尤其适用于猪在实际条件下可达到的体蛋白沉积上限、生长各阶段的采食量以及可考虑的替代饲喂策略。提供了在加拿大条件下猪生长模型商业应用的一些说明性实例。
Pig growth models can be useful tools for identifying optimum management strategies for individual grower-finisher pig units, by integrating knowledge of nutrient utilization for growth and animal-environment interactions into one system. In addition, these models can be used to demonstrate basic principles of nutrient utilization for growth in the pig, to examine "what-if' scenarios, to aid in the development of pig breeding programs and to develop effective research programs. Models used in commercial pork production should represent the biology of growth in the pig and should be flexible, so that they can be focused easily on the needs and special conditions pertaining to particular growing-finishing pig units. For proper application of pig growth models in practice, pig units should be characterized reasonably accurately. This applies in particular to the upper limit to body protein deposition that pigs can achieve under practical conditions, feed intake at various stages of growth and the alternative feeding strategies that can be considered. Some illustrative examples of the commercial application of a pig growth model under Canadian conditions are provided.
