Castration
• Reason
– In the United States and Canada, intact males cannot be
marketed for meat
– Due primarily to “boar taint”
– ONSET OF PUBERTY
– Castrated after puberty: “stagging” odor disappears 34 wks. After castration
– Improve feed conversion
– Easy to handle
• Age: 2 to 4 weeks (some: 1-2 day old)
Castration (cont’d)
• Restraint
• 50 lb. – hind limb or V trough
• Procedure:
• Check for hernia
• Disinfectant
• Lidocaine: 2-3 ml, 25 gauge needle
• Bard Parker no. 3 scalpel handle - no. 12 blade
• The testicles are pushed cranially the incisions and pulled to expose
the spermatic cords.
• A longitudinal 1-cm incision is made directly over each testicle.
• Spermatic cords must be severed : “tease”/ piglet emasculator.
• Antiseptic – heal in 5 – 7 days
Castration (cont’d)
• Older pigs
– Open castration
