I have noticed a lot of goats being passed off as hybrid ibex that are not. Some intentionally and some people just don't know the difference.
This billy has no ibex, he is a Alpine dairy goat billy.
Here is another Alpine dairy goat. As you can see they can have big horns.
And another. None of these have ibex in them, but this type has recently been selling for hybrid ibex and bringing good money.
Here is a Pygmy goat billy. Some of these have ibex shaped horns.
Here is another Pygmy billy. They can have the ibex horns and have the shoulder strap like this one.
Over the years we have bought a lot of the dairy billies and hunted them as Catalina's. We hunted the Pygmy's as African Mt. Goats. They are both unique in their ways, but they are not ibex. Because of their ibex type horns ibex breeders has used these breeds to breed with to have good hybrid ibex. I have personally crossed our ibex billies with a few Alpine dairy nannies where we would have some hybrid billies available to hunt at a cheaper price than our pure ibex. These hybrids will grow extremely fast. Big horns with big bodies. Hope this helps and maybe clear out any confusion.
