Animal Health & Welfare

The difficulties of bull management, the demand for more desirable steer carcasses and the lack of demand for bull carcasses dictate that castration be included as an essential part of herd management on many farms. However, stock-keepers should consider carefully whether castration is necessary.

There is a belief that castration improves conformation of the body thus producing a better quality product. Castration is also performed to:

• Maintain general control of the stock
• To avoid indiscriminate breeding
• To improve meat eating quality

It is further justified on the grounds that it improves an animal's overall welfare, for example by reducing injury amongst intact animals as a result of male dominance or sexual behaviour.

Castration is a regulated procedure and is specifically outlined in the Scottish Government Code of Recommendations for the Welfare of Cattle (link on the right).

Methods

There are 3 main methods of castration used on cattle:

1. Rubber Ring (RR) which causes scrotal necrosis and eventual shedding of the structures including the testes

2. Emasculator (e.g. Burdizzo clamp or Richey Nipper) which crushes the spermatic cord and causes irreversible damage to the vessels supplying the scrotum

3. Open or surgical method, where the scrotum is cut to reveal the testes which are removed by tearing, cutting or twisting

For a comparison of these methods with regard to their impact on animal welfare, use the 'Comparison of Castration Methods' tab in the menu to the left.

These procedures have a profound effect on the animal's behaviour including increased rates of kicking, rolling, restlessness, foot stamping and abnormal postures. These behaviours indicate possible pain and it has been shown that the application of local anaesthetic may reduce the associated suffering. As a result, castration is a procedure that is governed by the Protection of Animals (Anaesthetics) Act 1954, as amended.
