| 摘 要： | 在约束条件为原料组份及比例（xn）、原料营养素含量（aij）、原料价格（cn）及能量、粗蛋白、部分限制性氨基酸及矿物元素等主要营养参数指标（bm）条件下，用数学建模的方法建立了畜禽饲料配方设计的数学模型， 并在满足畜禽营养标准的前提下，获得成本最低(z)的畜禽饲料优化配方。另外，通过对开产期至高峰期（产蛋率＞85%）饲料配方设计的实证，推荐了一个科学、简便、实用的畜禽饲料优化配方EXCEL求解方法。

| Abstract: | In this paper,the mathematic modeling of designing feed formula was established,and the parameters included feed ingredients,their proportion,feed price and nutrients compositions were analyzed.Through introducing the designing process and solving method by the handy EXCEL program for layers feed formula during the stages from perinatal period to the peak,the author put forward a scientific,simple and practical method to design feed formula for feedstuff producer. |
