Sadly here in SA the two sectors of the same breed really doesn't work together well. Some horned breeders even advertise the horned cattle to fix the problems of the polled cattle. I've recently visited a few herds both horned and polled and at least here in SA I can't see the advantage the horned guys are claiming to have over the polled. They are not thicker, nor do they have more width and pigmentation, what I have to admit is that mst horned herefords have better eye set. As for the polled cattle, they have better udders and is in my opinion growthier and they maybe have a touch more width between the pins.
I breed mostly polled, but have a few horns and to me it doesn't matter if a horned bull gets sold or a polled bull, as long as its a hereford, because that is to the breeds advantage and in future better for both the horned and polled market. I don't think infighting within the breed does anyone's marketshare any good.
