摘要
应用优化理论研究了肉牛生产系统的最大收益饲料配方问题,并根据我国北方农区舍饲育肥牛的实际,建立了肉牛最大收益饲料配方模型。讨论了肉牛最大收益饲料配方模型的目标函数、约束条件、粗饲料约束因子以及计算输出,并建立了计算软件进行了实际计算。应用我国北方农区肉牛饲料原料,通过最大收益饲料配方模型,给出了计算结果。还讨论并给出了肉牛精料消耗最省的饲料配方模型及其计算。
The problem of maximum profit feed formulation for beef cattle productive system was studied by optimum theorem in this paper.Based on the fact of dry-lotfinishing beef cattle in NorthChina,the maximum profit feed formulation model of beef cattle and its computational software was built.The objective function,constrained condition,constri- ained factor as well as outputs for the maximum profit feed formulation are discussed.Using beef cattle feed raw material for the agricultural area of NorthChina,computer calculated re- sults through maximum profit feed formulation were presented.In addition,the minimum concentrated feeddepletion formulation modle for beef cattle was also given and discussed. The signification of applying these programs to the beef cattle raising was discussed.
