Parasite Alert: Barber’s Pole Worm

Conditions are now ideal for the proliferation of Barber’s Pole Worm. Cool nights and mild days with an abundance of green feed provide the perfect environment for a rapid worm build up.

Symptoms

Barber’s Pole Worm is hard to detect as sheep do not scour. Look out for these sypmtoms:

  • lethargy
  • depression
  • anaemia (acute cases)

Suggested action

Conduct faecal egg counts at least every 3 weeks, especially in young sheep.

Monitor lambs and weaners closely. If you notice sheep falling behind while mustering drench immediately and leave alone.
