影响猪遗传评估效果的主要因素研究

The Development of Pig Genetic Evaluation

综述了影响猪遗传评估效果的主要因素和猪遗传评估的发展趋势。影响猪遗传评估效果的主要因素有猪遗传评估方法、计算技术以及环境效应 (包括方差异质性 )、选择、非加性效应、非正态分布、性状间相关、有重复的记录等模型制约因子等方面。此外 。

The affecting factor and trend of pig genetic evaluation was reviewed.The main factors which influence pig genetic evaluation include genetic evaluation's methods and caculating techniques and enviromental effects, selection,non additive effects, non normal distributions, correlations among traits and repeated records ,the application to genetic parameter's evaluation based on bayesian methodology was also introduced in this paper.
