Why do dairy goats need their horns burned?
I have both dairy and fiber goats and fiber goats have horns but dairy goats you have to burn their horns. What is the difference?

It is not necessary to remove horns, but it is done for safety reasons (human) as well as it is easier for animals to get their head into hay feeders. Mostly, it is done for ease of handling and because they can get their heads stuck in feeders and fences.
Also, rarely, the horns can grow in a circle and bother the eyes, but that is easily fixed.
I am not a dairy expert, so if you sell milk, I do not know if there is any sanitary requirement for milking herds to remove horns. I have never seen any but just a thought.
