The data from the study came from two genotypes of cows (Holstein and 3/4HolsteinX1/4Bunaji). Milk yield, six body traits (stature, ST; chest width, CW; body depth, BD; heart girth, HG; rump width, RW, chest ligament, CL) and four udder traits (rear udder height, RUH; rear udder width, RUW; udder clearance, UC; teat length, TL). Multi-trait animal models were used to estimate the (co)variance components based on average information restricted maximum likelihood method (AIREML) using R 3.0.3 software.en3/4HolsteinX1/4BunajigeneticAIREMLmilk yield.Article
