Dehorning - Jokaku (English spelling)

Japanese: 除角 - じょかく（英語表記）dehorning

This is a procedure to remove the horns from calves and kids one or two weeks after birth, making them easier to manage. They become milder, but it does not affect lactation or reproduction. The method of dehorning is to lay the animal on its side, cut the hair from the area where the horns will grow, rub a rod of caustic potash on it to break down the horn tissue, and then apply tincture of iodine or similar to the scar to disinfect it. Another method is to burn it with an electric iron. This was mainly done on dairy cows, but as group rearing in drive-in and open barns has become more common for beef cattle, dehorning has also become common.

生後1，2週間に子牛や子やぎの角を除いて育成管理を容易にする処置。性質は温和になるが泌乳や繁殖には影響しない。除角の方法は動物を横に倒して角の出る部分の毛を刈取り，棒状のカセイカリをこすりつけて角組織をこわしたあと，傷跡にヨードチンキなどを塗り消毒しておく。また電気ごてで焼く方法もある。おもに乳牛に対して行われたが，肉牛でも追込み式や開放式牛舎での群飼いが普及するようになったので，除角するようになった。
