摘要
用江苏省14个牧场的2268头乳牛第1胎305天校正产奶量资料,对1980～1988年间使用的18头种公牛用7种方法评定育种值,并对这些评定方法进行比较。结果表明:RBV 法、BLUP-NR 法和BLUP-WR 法间顺序相关及育种值相关均在0.9以上,是较好的评定方法.
Using the corrected 305-day first-born milk yield data of 2 268 progeny of 18 Holstein bullsin 14 dairy farms during 1980～1988 in Jiangsu,the breeding values of 18 bulls were evaluated by sevenkinds of methods,and these seven evaluating methods were compared.The results show that the rank andproduct moment correlations between RBV and BLUP-NR or BLUP-WR are more than 0.9.So they arebetter evaluating methods.
