Most cattle breeders have idiosyncrasies on what they will or will not tolerate from the animals in their herds. It might be growth, condition, udders, disposition, or even simple color markings. I think for me I will tolerate "some" attitude as long as the animal keeps easy and raises a decent calf. I won't tolerate a non functional udder, although I have some borderline ones which keep them on my "first to go" list! I also won't tolerate an animal who thinks the grass is always greener on the other side of the fence (bull or cow)! How about y'all?
