The loss of antlers and horns is one of the key characteristics of domesticated herd animals. They don't need them for protection against predators or intra-species rivalry, because a) we humans and our dogs do all the defensive work and b) we humans control how they mate with each other so there's no benefit for males to fight for resource and mating rights. When I say "sheep" above, I'm referring to domesticated sheep, as is this article, not their wild cousins which certainly have different behavior.
