Either you all can enlarge that picture, or you have way better eyes than me. I've shot a couple goats, a billy and a nanny, and I'll be damned if I can see that picture well enough to know exactly what that anatomical part if, anymore than we can acertain the size of the glands. It looks just as much like the goat's rectum to me, as it does female parts. Perhaps a better picture would make things more clear.
Better yet, why doesn't the starter of this thread tell us what hte goat was.
