Of the breeds you listed, I would choose simbrah, but without knowing what the cows are crosses of, climate and forage conditions, etc., it would be impossible to make a realistic recommendation. A lot also depends on what market you are in and how different calves sell in your area. In our general area in southeast MO almost all calves with any ear take a hit at the sale barns - not because of their quality, but because the buyers can do it. I don't blame them because we all have to make money sometime and somehow or we'll all be out of business. I just don't raise calves with any ear.
