Unregistered, where exactly is the split? The hoof itself is like your fingernail, and won't heal back together, but if it's on the foot, I'd clean it well, disinfect and wrap the foot with gauze and vet wrap. Keep an eye on it and change the bandages daily or at most, every two days, keeping the goat out of wet areas. Probably could use an antibiotic, too. Jan in Co
