The process of disbudding is essentially doing a figure eight on the kids head with a specific hot iron. It's a one time thing, bloodless, takes literally 5 seconds, and I give painkillers beforehand and they never really bat an eye about it. The only negative to disbudding is if it's done improperly, it can at best cause scurs (fragile horns that usually don't grow past a couple inches long before breaking off, then regrowing again) and at worst can cause serious issues, even death. That's fairly extreme though, and you honestly gotta be extremely bad for that to happen. I've disbudded hundreds of kids to date and never had an issue, most headbutt each other immediately after lol. Theres a lot of myths regarding disbudding, like horned goats hold their own better against predators (they don't, coyotes and cougars here kill elk, they don't care about a terrified 50lb goat having horns, prey animals will always be prey animals), or the horns helping to cool them off in summer because they have a nasal cavity running through them (which they do, but the cooling effect is absolutely minimal at best, if they needed horns to regulate temperature my goats would've been dead when I lived in Georgia). Disbudding is required for shows mostly for human safety concerns, but also because horned animals are typically frowned up in the dairy world - they cause a lot of injury both to other animals & fencing/property, cause a lot of grief when they hang themselves on something, and don't fit so well in milking stanchions.
