摘要
应用系统分析的思想和方法,分析了影响动物育种改良经济效益的主要因素及相互关系,并在定量描述这些相互关系的基础上探讨了育种方案的优化方法。此外,对预测育种收益的基因流动法原理作了简单介绍。在基因传递矩阵和性状实现向量的确定方面提出了新的见解,并提出了育种投资动态回收期线性插值计算方法和综合育种值中经济加权值的两次加权计算方法。
System analysis are used to study the main factors and their interrelations which affect economic efficiency of animal breeding improvement and the optimization of animal breeding scheme.Furthermore,the author introduced the discount-gene-flow method.Personal view are put on the decision of gene-transmission matrix and incidence vector.New methods of calculating the dynamic-pay-period by linear interpolation and the weight values of produc- tion characters in aggregate breeding value by double weighting are also suggested.
