Small ruminant castration

For castration, small ruminants are essentially small calves. The same techniques apply

  • surgical
    • blade to open the scrotum with testicle removal by traction, emasculator, or ligature
  • bloodless
    • Bander/rubber bands – considered the most painful and may be inhumane in older goat kids
    • Burdizzos- stagger crushes to avoid the same issues seen with banders
    • Callicrate bander – for older goats
    • Short scrotum method – the scrotum is banded, leaving the testicles in place but pushed close to the body

Goats are very sensitive to pain so it is essential to provide sedation and analgesia. Goats are also very sensitive to lidocaine. A maximum dose of 4 mg/kg is recommended. The lidocaine can be diluted to make the small volume go further; this does result in a shorter duration of action. Hint : Lidocaine is 2% or 20 mg/ml. Preoperative NSAID options include flunixin meglumine iv or meloxicam orally. Sedative options include xylazine or detomidine (careful with xylazine dosing and avoid these drugs in sheep) or  diazepam/ketamine.

Goats are also prone to tetanus so should receive tetanus vaccination.

Many goats are disbudded and castrated in the first week of life. Pet goats might benefit from more growth prior to castration, particularly in case it helps urethral diameter.

How to castrate a goat

Key Takeaways

Small ruminants may be castrated by surgical or crushing techniques; banding is not ideal and is being gradually replaced by the short scrotum method in other countries.

Goats need preop analgesia and local blocks; sedatives can be helpful. Be careful with xylazine in sheep.

Small ruminants are sensitive to lidocaine; careful dosing is essential.

All small ruminants need tetanus vaccination.
