摘　　要：饲料的有效能可用于猪的维持、生长、繁殖和泌乳,饲料原料品种、种植年份、气候环境、储存条件、加工工艺等多种因素均会造成饲料原料理化参数及有效能值的变异.研究表明,猪饲料原料中多种化学成分与饲料原料的有效能值显著相关,通过建立基于不同饲料原料化学成分的预测方程可以较为准确地评定其有效能值,从而达到精准配方的目的.文章就猪常用饲料原料中理化参数和有效能值的变异情况、影响猪饲料原料有效能值的关键化学成分、基于猪饲料原料化学成分预测其有效能值的数学模型及其在饲料配方中的应用作一综述,以期进一步深化对饲料原料与有效能值间构效关系的认知,并推动猪饲料的精准配制.The available energy of feed can be used for the maintenance, growth, reproduction and lactation of pigs. A number of factors including varieties, growing years, climate, storage condition, processing technology can lead to the variation in physical and chemical parameters and available energy value of feed ingredients. Studies have shown that the correlation between chemical components and available energy in feed ingredients of pigs is significant. Establishing prediction equations for different feed ingredients based on their chemical compositions is a great way to evaluate the available energy of feed ingredients and achieve the goal of accurate diet formulation. In this paper, the variation of physical and chemical parameters and available energy value in main feed ingredients of pigs, key chemical components affecting the available energy of feed ingredients in pigs, mathematical models predicting available energy based on chemical components and application of the models in feed formulation are reviewed. It is expected to deepen the cognition of structure-function relationship between feed ingredients and available energy as well as promote the accurate diet formulation for pigs.
