Which tool is designed to apply a band around the scrotum to castrate by constriction?

• A. Scalpel
• B. Elastrator
• C. Emasculator
• D. Newberry Knife

Answer: (B)

This item is testing knowledge of tools used for banding a scrotum to castrate by constriction. The tool designed for this purpose is the elastrator. It is built to place a tight elastic band around the scrotum, which constricts blood flow to the testes. Over a short period, the tissue deprived of blood supply dies and the scrotal contents are expelled, accomplishing castration without a surgical incision. This method is commonly used on very young animals, like lambs or kids, because it’s quick and avoids cutting, but it requires proper technique, correct band size, and attention to welfare and tetanus prevention.

By contrast, the scalpel, emasculator, and Newberry knife are surgical instruments used for incising and tying off the cord or destroying tissue through cutting and crushing, rather than constriction with a band.
