Burdizzo Castration Clamp

Castration by crushing the cord

  • Cross-sector husbandry
  • Early life
  • Calves, lambs, and goat kids

What it is

Heavy metal jaws close over each spermatic cord and crush it through unbroken skin. The blood supply is cut off and the testis withers.

Where it sits in the system

Castration lets farms control breeding, blunt male behaviour, shape the carcass, and keep males and females in the same group. The clamp leaves no open wound, which is why it is chosen over cutting.

Welfare concern

Crushing the cord causes acute pain, swelling, and an inflammatory response that lasts well beyond the moment of the procedure. A misplaced clamp can leave the castration incomplete, or mean the animal is clamped a second time.

Worth being precise about

Age, operator skill, pain relief, and infection control all change how bad this is, and whether the animal needs castrating at all is a separate question. 'Bloodless' describes the skin, not the pain.
