DMU、GBS和Herdsman3个软件育种值估计的比较
Comparison of Breeding Value Estimation by DMU, GBS and Herdsman
摘要
Abstract
The breeding and management in pig farm can benefit from professional software,which are helpful to upgrade pig breeding in China.Generally,breeding value estimation is the core among these breeding software,while the inconsistence of estimated breeding values (EBVs) of same animals from different software always confused animal breeders.Therefore,we investigated three popular software,DMU,GBS and Herdsman using pig breeding data and simulated data.Our results showed that the EBVs obtained from DMU4 were as highly as 0.99 correlated with those from GBS in the same scenario,as these two programs share same algorithm to estimate breeding value.DMU5 kept high consistence with DMU4.DMUAI generated higher accuracy in EBV than GBS and DMU4 as REML algorithm is implemented in DMUAI.Although EBVs from Herdsman were very low correlated with those from DMU and GBS,theoretically,Herdsman is supposed to has high consistence with DMU and GBS in same scenarios due to their common algorithm.Our results also indicated that breeding software do not take significant effect on the breeding value estimation,the model for genetic evaluation played more important role on the inconsistence of EBV.关键词
