Comparison of predictive ability of single-trait and multitrait genomic selection models for body growth traits in Maiwa yaks.

Abstract excerpt

Yaks are grazed extensively on the Qinghai-Tibet Plateau, which has a long history of semi-domestication. The predicted weight of yaks over consecutive years helps make strategic decisions when selecting yak calves for breeding. To achieve more accurate predictions of genomic estimated breeding values, we used a dataset comprising the genotype and weight records of 396 Maiwa yaks collected from 2015 to 2020. We...
