Beefmaster is one of the few breeds that solely bred for performance, not asthetics. Who would have thought that would have become such a foreign ideology.One of the things I don't like about Beefmaster is that they are so inconsistent in appearance. They can look like a European cross or like a long-eared brahma cross. Long legged and rangy with a lot of extra skin or short legged, stout, and rolling in fat. White faced, brockle faced, or solid.
If you get a bull with no obvious ear he would probably not throw calves with any ear. I can't say he would breed true to type (his type) but he might. If you don't want ear I would avoid the bulls with that trait. Some of your cows have some ear so they might get it from the maternal side anyway.
You should have heard me steering my family away from some paint bulls. They were looking at me as stupid as I felt trying to explain it.
