76
Q

Euthanasia - mechanical

  • Boar needs to be max 1 m away from sows
93
Q

Heat detection

A
  • Boar stimulation
  • Bring boar to sow, then apply back pressure - astride by stockman, when won’t move when sit on = will stand for insemination
  • Enlarged vulva
  • Avoid habituation (continual boar exposure), rotate boars - expose sows to diff services + allow boar to have some natural services
  • Check for returns at 18 - 24 d
94
Q

AI

A
  • Have all supplies in place
  • One boar per 5 sows maximum
  • Do not inseminate unless solid heat seen

  • Wipe the vulva with a dry towel
  • Use non-spermicidal gel on
    catheter tip
  • Insert catheter gently at ~45
    degree angle
  • Push firmly towards cervix
    (rotating if necessary)
  • If in place, resistance to pulling back on catheter
  • Connect semen dose to catheter
