Abstract excerpt

In this study, we aimed to estimate heritabilities and genetic correlations over time using within- and across-trait predictivity with complete and trimmed references in a large, genotyped population. The data, provided by the American Angus Association, included birth weight (BW), weaning weight (WW), and post-weaning gain (PWG) records from 10,045,726 animals collected from 1972 to 2025, a pedigree of...
