Surgical castration - Kanketsukiyoseiho

…The timing of castration varies, but in cattle it is usually before 6 months of age, and in pigs it is usually before 1 month of age. Castration methods include open castration, in which the testes are surgically removed, and bloodless castration, in which the spermatic system is ligated with thread or rubber bands or crushed with forceps.

*Some of the terminology that refers to "invasive castration" is listed below.
