i like an eared cow, not necessarily an eared bull. I stay at 3/8 on my cows, and breed them to a charlois, black sim, or lim-flex. I like they way they milk, mother, and I especially like my weaning weights.
People that think Ky doesn't have the heat for eared cattle, have never had any. Sure our winter is to harsh for a full blood, but our summers are fine for 3/8. Infact, in the summer my cattle will divide themselves in to two herds. One group lays in the shade, and stands in the pond. One group heads on out to graze.
My calves on those cows, show very little Brahman influence. They are usually in a graded pen at the sale with their counterparts.
I'm trying to flip my herd to 100% Brahman influence. I'm having to buy replacement heifers to do it. I might need to cover my "non eared" cows with Brahman influence bull to ever get there.
