This week we examine Barbers Pole worm in sheep, also known as Haemonchus contortus. It is a blood sucking worm that doesn’t cause scour. Instead, anaemia is the principle symptom observed. On farm, first report will be well-conditioned sheep suddenly going down when driven, with pale conjunctivae on inspection.
The worm gains its name from the its appearance, resembling a Barbers Pole and though it doesn’t overwinter well, it is extremely prolific – it can multiply on pasture very quickly. A good infection can involve 5000 worms which collectively could remove 250ml of blood from a sheep daily.
Adult sheep are at risk from Barbers Pole worm as well as lambs.
Oedema is a common symptom of a Haemonchus infection and so an infection can often be mistaken for chronic liver fluke.
White, yellow and clear wormers are all effective against the parasite.
Moxodex has five-weeks of persistent activity post-dosing against Haemonchus contortus.
