Table 6 Correlation (rEBV,SMGS) between EBV and pre-progeny test sire maternal-grandsire EBV prediction and correlation (rEBV,GEBV) between EBV and GEBV in young bulls for five methods

From: A comparison of five methods to predict genomic breeding values of dairy bulls from genome-wide SNP markers

  1. GEBV predictions for bulls born between 1998 and 2002 were calculated by combining the MBV predictions with the sire maternal-grandsire pathway predictions, which were calculated at the time of birth of the young bull calves; ASI: Australian Selection Index; PPT: protein percentage; FR-LS: fixed regression-least squares; RR-BLUP: random regression-BLUP; Bayes-R: Bayesian regression; SVR: support vector regression; PLSR: partial least squares regression.
