Procedure
Elastration involves restraining the animal, without the need for anesthesia or sedation (unlike most other castration methods), in a position that provides access to the genitals. Special ''elastrator pliers'' are then used to place a tight

. This cuts the blood supply to the scrotum and testicles, which will totally decay and slough off within a few weeks. Care must be taken during the procedure to ensure that both testicles are fully descended and properly located inside the scrotum, and that the animal's nipples are not included within the ring. Elastration is normally limited to castrations done during the first few weeks of life, and it cannot be used for species where the scrotum does not have a narrow base, such as

s. It is commonly recommended to not use this method on goats until they are 8 weeks or older. This is due to possible complications that could occur later in life like urinary
calculi. Goats that are banded during the first month of age are most at risk.
Possible complications
The country of Lithuania has banned the practice due to their belief that the procedure is inhumane. There is some evidence that elastration is more painful if carried out on older animals, although much of the immediate pain of application can be prevented by injection of local anaesthesia into the scrotal neck and testicles. Practitioners usually try to elastrate as soon as possible, once the testicles have descended, to reduce the amount of dead tissue, infection, and accompanying complications.
However, with some animals such as goats, castrating too early increases the frequency of

, so elastration may be postponed. If bull calves are castrated within the first one or two days the testes may sometimes be small and soft enough to be drawn up through the ring, and they continue to develop above the scrotum – surgical castration then becomes necessary.
Improper use of banding can result in death and charges of cruelty.
Docking
The same tool and rings are also used to
dock the tails of many breeds of sheep, to prevent dung building up on the tails (which can lead to
fly strike). This is usually done at the same time as castration of the ram lambs.
