Five eighths shorthorn I believe. They fit with the rest of my cattle. A little lighter red maybe.You know it will. The Shorthorn -Highlander cross has been big time for the highest grading beef in the British (AND OTHER) Isles since the cattle have existed there. 200 years more or less. Same with the Blues from the Gallowayx Whitebred Shorthorns. A luing aI would have to be a hiefer bull with a useful live calf Showring or not . I am assuming Luings are more or less 50% Shorthorn genetically
