Equine castration

EQUINE CASTRATION

  • To make the animal docile.
  • Testicular tumor.
  • Scrotal hernia

Aneathesia  

  • For standing castration local infiltration analgesia can be used.
  • For castration of recumbent animal xylazine 1.1 mg/kg + ketamine (2.2 mg/kg) or xylazine 0.5 mg/kg+ thiopentol 6.6 mg/kg.

Techniques

  • Closed method 
    • Parietal layer of tunica vaginalis is never opened before transfixation ligature.
  • Open method 
    • Parietal layer of tunica vaginalis is incised before emasculation of spermatic cord.
  • Half closed 
    • Parietal layer of tunica vaginalis is incised and testis removed.
    • Before removal spermatic cord is ligated and tunica vaginalis also ligated before closing.

Procedure

  • Two parallel incision equidistant from median raphae in cranio-caudal direction.
  • This incision made through skin dartos, blunt dissection to free the testes and spermatic cord, fascia.
  • An incision made through tunic proximal to cranial pole of the testes and testes prolapsed from tunic.
  • Emasculator placed proximal to testes advanced upwards.
  • Mesorchium is perforated to separate vascular and avascular part.
  • Emasculator is applied first to neurovascular portion before removing avascular part.
  • Emasculator applied directly and should remain for sometime.
  • After both testes removed remove loose tags of fascia, fat.
  • The wound should not be sutured.
