This study demonstrated highly significant ( p ≤ 0.001) negative correlations (−0.28 to −0.74) between HT and GEBVs for current Australian dairy cattle selection indices (BPI, ASI, HWI) and significant ( p ≤ 0.05) positive correlations between HT and GEBVs for traits like FS (0.45) and fertility (0.25).
