Alert for deadly Barber’s pole worm in sheep
SHEEP deaths in southwest Victoria as a result of barber’s pole worm this summer has prompted Agriculture Victoria to warn of the dangers of the blood sucking stomach parasite.
SHEEP deaths in southwest Victoria as a result of barber’s pole worm this summer has prompted Agriculture Victoria to warn of the dangers of the blood sucking stomach parasite.
Agriculture Victoria senior veterinary officer Paul Beltz said the parasite thrived in warm, moist conditions where it could build up very quickly and result in the death of affected animals.
“Barber’s pole worm (Haemonchus contortus) is present on farms across Victoria but rarely causes disease as our climate doesn’t normally favour it reproducing rapidly,” Dr Beltz said.
“Female barber’s pole worms lay large numbers of eggs, so a rapid population explosion is likely when weather conditions favour it, such as those that we are experiencing now.
“Sheep producers now checking their stock for flies should also be aware of the symptoms of a barber’s pole worm infestation.
“Affected sheep will be weak and have very pale eyelids and gums.
“This worm does not cause scouring and affected sheep will have firm pellets. In some instances, the first sign may be sheep dying.”
A faecal egg count or sheep necropsy test can help diagnose the condition, which most drenches can control in Victoria.
