Here an opinion that is sure to get some scoffs, a few years back my brother needed a buddy calf for his kids 4h steer so he bought a Holstein calf from a milk operation for 50 bucks, it ate right next to the angus market calf for 16 months. They were both butchered at same time same locker, I was hesitant but its probably the best tasting home raised beef I’ve ever had, and that coming from someone who has raised angus and black baldie cattle all my life. The only caveat was the Holstein did not dress carcass weight as well as the angus calf.
