Animal Overview

Lonestar is built on Arubial United P0342 — the same foundational sire whose son Arubial T1701 produced the $70,000 North Shores Iron Prairie at the 2026 Big Texas Wagyu Sale, one of the highest-selling animals in that record-setting event. When the industry paid $70,000 for a T1701 daughter, they were paying for United P0342 genetics. Lonestar IS a United P0342 son — his offspring carry the same foundational bloodline one generation closer. At BFI +549 and EMA +10.6 in the Top 8% worldwide, Lonestar adds the carcass scope and ribeye area that supply chain programs reward most consistently at the rail. Semen available direct from the Carlog ranch in Colorado — no auction floor, no intermediary, direct access to the bloodline the Big Texas ring confirmed at $70,000.
