Someone already answered it but bulls are still fed out. They don’t gain as quickly but they’re still worth $2500 a piece at time of harvest… Holstein also is some of the highest marbling meat you’ll find grades choice and prime more often than many other cattle just takes more time and feed.

Most freemartin calves are not euthanized, in fact none are nor should be unless other congenital/genetic defect exist such as PHA, cleft palate etc. They are fed and harvested as beef. No ovarian hormone production so actually feed similar to a steer. I’m specifically a bovine veterinarian in the heart of cattle country.
