Expected calf parent-average PTA
Estimate
Calculated as (dam genomic PTA + service sire PTA) ÷ 2. These are parent-average estimates only, rounded to the nearest full digit; they are not official genomic evaluations of the resulting pregnancy or calf.
Detailed genetic codes are retained for reference without crowding the animal overview.

Sale reference note
Genomic information is displayed for HighHopes-Halcyon sale reference. Figures are taken from the supplied USA, Canadian and UK proof files and should be interpreted within each proof system rather than blended across systems.
Data note
Reference information only
Genomic, production and service information is provided for sale reference only and reflects supplied files available at publication. Values may differ from future official evaluations or later milk recording updates.
Expected calf PTA/PA figures are parent-average estimates calculated from the dam genomic proof and supplied service sire proof. They are rounded to the nearest full digit and are not official genomic evaluations of the resulting pregnancy or calf.
