O'Hanasaki Whitney

A genuinely elite young female. Ohanasaki Whitney sits in the top 1% of her 2024-born Japanese Black reference cohort for the Breeder-Feeder Index (BFI 653, against a breed average of 302), backed by top 3% Fullblood Terminal (507) and top 2% F1 Terminal (446). Three indexes, all in the top few percent — this is not a one-trait animal.

Where it counts on the rail, she’s exceptional: top 4% for Marble Score (+3.3), top 8% for Marble Fineness (+1.07), top 5% for Eye Muscle Area (+11.3 sq cm) and top 11% for Carcase Weight (+50 kg). She pairs that carcase merit with real growth — top 14% for 600-day weight (+48 kg) — and does it efficiently, ranking top 10% for Net Feed Intake (-0.28). Rare to find marbling, growth and feed conversion stacked in the one package.

Maternally she’s just as well set: top 16% for Mature Cow Weight and 200-Day Maternal, from the Ohanasaki cow family. Sired by Arubial United P0342 (AI)(ET) — a Eifel Wagyu S05242 son out of a Mayura P0056 daughter — and out of Ohanasaki Tiffany (AI) by Arubial Anticipated Q0014.
