摘要
本研究借助“差额法”推导出一系列奶牛育种目标性状的边际效益计算公式。并计算出北京地区黑白花奶牛确定育种目标时各性状的边际效益。经统计分析表明,北京奶牛群的乳用、肉用和次级性状经济重要性之比为2:1:2。
Formulas for the calculating the marginal profits of objective traits of dairy cattle have been deduced by the Difference Method. Marginal profits for traits in determining the breeding objective are calculated for the population of White and Black dairy cattle in Beijing area. Statistical analysis shows that the economical importances of lactation, beef and secondary traits in this population are in the proportion of 2 : 1 : 2.
