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.
Barber’s Pole Worm is hard to detect as sheep do not scour. Look out for these sypmtoms:
- anaemia (acute cases)
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.
