| 摘 要： | 本文以黑龙江省猪品种资源构成、养猪生产具体条件及过去杂交试验等为基础，拟定了二元、回交和三元杂交方案．在系统分析的基础上，运用线性规划模型优化了不同杂交方案下不同品种组合的猪完整繁育体系内猪群结构．得出，不同杂交方案下猪完整繁育体系各阶层母猪群的最优数量结构呈金字塔形．

| Abstract: | A linear programming model was used to optimize sow herd structrue in the integrated breeding system under different cross projects. The results obtained from the linear programming model shoved that the optimum structure of sow herd in the integrated pig breeding system is pyramid-like. |
