摘　　要：我国规模化集约化猪场现行三阶段饲养模式存在饲料浪费、养殖成本增加、环境影响加剧和生产效率低下等问题,精准饲养系统实时监测生长育肥猪生长状况,利用二次指数平滑法和生长预测模型预测猪只采食量和营养需要量变化,结合饲料原料营养价值快速评定技术,针对不同个体制定个性化饲养方案,可有效节省饲料资源消耗,提高生猪养殖利润,减少生猪养殖碳排放等环境影响,促进生猪养殖业可持续发展,有利于缓解我国粮食进口压力,保障国家粮食安全。本文综述了生长育肥猪精准饲养系统的技术要求、应用现状与发展趋势,以期为深入理解并完善生长育肥猪精准饲养系统奠定基础,为应用、推广精准饲养系统以促进生猪养殖业可持续性发展提供指导。The current three-stage feeding mode of large-scale intensive pig farms in China has many problems,such as waste of feed,increase of breeding cost,intensified environmental impact and low production efficiency. Precision feeding system monitors the growth status of growing-finishing pigs in real time,predicts the changes of feed intake and nutritional requirements of pigs with growth prediction model and quadratic exponential smoothing method,and formulates individual feeding programs based on rapid evaluation of nutrient value of feed ingredients. Precision feeding system can effectively save feed consumption,improve the production profit of pig breeding enterprises,reduce carbon emissions and other environmental impacts from pig farming,promote the sustainable development of pig breeding industry,alleviate China’s food import pressure and ensure national food security. This paper reviews the technical requirements,application status and development trend of the precision feeding system for growing-finishing pigs,in order to provide a foundation for the deep understanding and improvement of precision feeding system of growing-finishing pigs,and to provide guidance for the application and promotion of precision feeding system to promote the sustainable development of pig breeding industry.[Chinese Journal of Animal Nutrition,2022,34(5):2752-2763]
