This bull is still developing — photos, performance data, and pricing will be posted as he grows out. EPDs below are current.
Actual performance
Weights recorded here and reported whole-crop through AHIR — ratios are against his contemporaries, not a curated group.
Where he fits
The growth bull of the pen — his 781 lb adjusted weaning weight at ratio 113 is the heaviest in the crop, with +137 YW behind it. He came into the world at 103 lb, so keep him on mature cows and let him do what he does: stack pounds on sale-day calves.
EPDs
As of Jul 24, 2026 · American Angus Association weekly evaluation · green marks = breed percentile rank
His dam’s record: Penz Heather Bloom 8559 — 3 calves weaned at an average ratio of 109, with 2 daughters raised and a 105 yearling average. Data tells you what a bull should do; the cow that raised him tells you the rest.
