The old stories about two headed calves or six eyes etc is bull. Unless the bull has hidden negative or undesireable traits the calf may or may not be as growthy. That's caused by the increasing of matched gene pairs (homozygosity), but it could also match up desireable traits. With in/linebreeding you have to be willing and able to cull mercilessly. Any negatives must be eliminated in breeding animals.
