Ok here's the deal, we have nothin but Commercial cattle, Mixed female herd with mostly brangus females but quite a few hereford crosses, and Heintz 57 red and yellow cows.(by heintz 57 I mean, brahman crosses) Ran with Brangus Bulls. There are no epd's to look at, at all here. Her mama is one of the non discript yellow cows. Not one I particularly like but she always raises a real nice calf so she's stayed. The next few years we'll be using Angus Bulls.
We breed most of the time at 15 months, and very seldom have we ever had any calving problems. Not one pull in 15 years. 1 or 2 that didnt mother good, but they went to town. We do some fall calving, so that wouldn't be a bad stretch to put her over into that group. But I'd much rather have her calvin in January or February, they just seem to do better for us here born at that time. Based on what she looks like now if she keeps up and looks good come fall, she'll most likely get to stay. It's awful hard to turn loose of a nice replacement heifer when they look like she does. It'll be a few more years before we can safely say we'll have all black mama's, LOL and by that time the new color will probably be gray ;-) not that we are chasin the color fad, I happen to like my black brangus cattle a whole lot. thanks for all your replies
