Honestly it's a waste of time and money from a breeder's perspective. It's not going to put my name out there through kids, and not going to be shown (very unlikely anyway) as I breed dairy. And really, a papered wether isn't going to do anything for anyone's herd anyway. Unless you're much into cloning. The other thing to think of is typically wethers are culled bucks. Not up to par to improve the breed for that breeder's plan. I pick one replacement buck (if good enough) after kidding is said and done and decide from there if I'd like to offer the rest for breeders, or if they're not up to par, I wether. I always keep the "worst" for personal consumption, as we love keepin meat in the freezer.
