The breeding values of 12 dairy bull, were evaluated by BLUP method, and the parameters μ, h_i, g_i, S_(jk were obtained by using computer. Comparing this evaluation with thnt of not using relationship matrix, there are some difference between them. In the calculation, A~(1-)should be added to the elements of bull, effect on the diagonal of matrix.

本文以南京市12头乳用种公牛(其中引进上海市6头、合肥市1头的冻精)为实例，应用公牛间有亲缘关系的BLUP法估计其育种值，电算求得参数μ、h_i、g_i、S_(jk，按育种值排列优劣名次，并与不加入公牛间亲缘关系的结果进行比较，发现两法间略有差异，其计算方法在矩阵对角线的公牛效应元素上加A~(1-)(即公牛间亲缘关系的逆阵)即可。
