摘　　要：本研究应用动物模型ＢＬＵＰ法在微机上评定了北京地区１９６５～１９９２年间出生的荷斯坦牛４１０８０头，建立了一套荷斯坦牛的动物模型评定系统。迭代求解采用间接解法，在阅读数据文件时进行。对于管理组、公牛与牛场互作、永久环境效应，采用Ｇａｕｓｓ—Ｓｅｉｄｅｌ迭代法，对于动物个体和遗传组效应，采用不完全的Ｊａｃｏｂｉ迭代法。提供预期传递力、父母传递力均数、预期生产力、表型均值等有用的遗传和生产信息。在配备了微机的农场或畜群不大的地区，移植本研究成果相当方便。An animal model evaluation system was set up and applied in evaluating by a micro computer 41080 Chinese Holstein individuals born in from 1965 to 1992 in Beijing.Solutions are obtained by the indirect method of mixed model equations ,which iterates on data when these data are read by computer.Fixed management effect,random herd sire interaction effect and random permanent environmental effect are computed by Gauss Seidel,and breeding value and genetic group effect by incomplete Jacobi.Results include some useful genetic and producing information,such as predicted transmitting ability,parent average (average transmitting ability of parents),predicted producing ability and performance average etc.It is flexible to use this system in the farms with micro computers.
