My sheep are dying overnight... this is something that sheep like to do!

Barber’s Pole is a gut parasite infection with the roundworm Haemonchus contortus. It is a huge worm and can be seen on postmortem with the naked eye, it infects mainly sheep but can be maintained on the grazing area by cattle too.

The spectacular feature of Haemonchus is the sudden death of affected animals without them scouring. This is because the huge gut worm burden drains them of their circulating blood and they die from anaemia and lack of protein. If you look inside the eyelid or mouth the membranes will be white due to the anaemia. We see Haemonchus when there has been rain after a dry period and animals are suddenly eating lots of larvae on the new grass. Ask your vet about the best drench programme to avoid problems with this parasite.
