Thank you for your comment. Wagyu beef fattening is kept in a limited space. Therefore, if the cows or bulls have horns, they may injure the outside cows by fighting for food, or they may hit the horns against the fence and get injured. It's a pity to cut the horns of cows, but to prevent injuries, cut the horns. It's no wonder people in countries that don't have the culture of cutting cow horns. There is no need to cut horns when grazing cows to feed grass or fatten grains. I think it's like cutting a horse's hoof and putting on a horseshoe.
