摘要
应用综合育种值作为数量化育种目标的方法选择梅花鹿的生产性状及其对应的选择性状。在对确定以茸用为主的梅花鹿育种目标时,除了主要考虑茸用性状外,还应适当考虑繁殖和使用寿命等性状,对于直接影响茸鹿生产效益的次级性状不容忽视。借助差额法推导出一系列梅花鹿育种目标中目标性状边际效益的计算方法,并根据调查与研究,给出计算边际效益的有关生物学、育种学和经济学参数,计算出各育种目标性状的边际效益。当这些参数发生变化时,可根据本文给出的计算公式重新计算。根据梅花鹿鹿群的基本情况和对目标性状相对选择重要性的计算结果,认为梅花鹿茸用性状、繁殖性状和使用寿命目标性状的相对选择重要性之比是8∶3∶1,而育种目标中长白山梅花鹿品系对茸用性状、西丰梅花鹿对繁殖性状应有所侧重。
The production traits and its corresponding selection traits in breeding objective for breeding scheme were determined by the method of using total breeding value as the quantitative breeding objectives. When the breeding objectives were determined in Sika Deer, besides the velvet traits were mainly considered, the reproduction and service life traits should be considered properly, and the secondary traits which directly affecting velvet deer farming profits could not be neglected too. The formulas for calculating the marginal profits of the traits in breeding objectives for velvet Sika Deer had been deduced by the difference method. Biological, genetic and breeding parameters and economic values of Sika Deer had been investigated, and the marginal profits for traits in determining the breeding objective of the population were also calculated. When these parameters or values were changed, the marginal profits for traits could be calculated again by the given formulas. The economic importance of velvet, reproduction and service life traits in Sika Deer breeding were nearly in the proportion of 8 ： 3 ： 1. In the objective traits, velvet traits in Changbaishan Sika Deer and reproduction traits in Xifeng Sika Deer should be taken seriously.
