摘要
通过对乳用种公牛常用评定方法的比较研究,揭示了不同评定方法的相关性和特点。结果表明:在我国牧场计算机应用不太广泛情况下,可使用女儿均值比较法和同期同龄法进行后裔测定。
A comparative study on methods of sire evaluation shows that the herdmate comparison method and offspring average milk production comparison method are practical to farms where computers have not been used widely.
