摘要
遗传评估作为家畜育种学的核心内容,是教学环节中理论性极强的一部分内容,需要结合实践数学,才能便于学生的理解。目前应用于家畜遗传评估的软件极多,WOMBAT软件具有参数设定简单、运行速度快等优点。以山羊产绒量和断乳重为例,建立单性状和多性状(无)重复力模型,利用该软件对以上性状进行有效的遗传参数估计,应用于课堂教学,利于学生了解遗传评估在家畜育种中的应用。
Genetic evaluation,as the core content of Livestock Breeding,is a highly theoretical part of the teaching process,which needs to be combined with practice to help undergraduates understand its content.At present,there are a lot of software applied in livestock genetic evaluation.Compared with the other software,WOMBAT software has the advantages of simple parameter setting and fast running speed.Taking the cashmere yield and weaning weight of goats as examples,we established a single trait and multi-trait (no) repeatability model,and used this software to estimate the genetic parameters of the above traits effectively,which can be used in classroom teaching to help undergraduates understand the application of genetic evaluation in livestock breeding.
