Barbers pole worm – an unusual but deadly worm in south western Victoria in sheep and alpacas

Adapted from http://www.wormboss.com.au/ Barbers pole worm – or more correctly Haemonchus contortus – is not usually a problem in south western Victoria. However, over the last few years we have seen isolated cases in spring and autumn. Barbers pole worm likes wet warm conditions and this has been the case in some recent seasons. Populations can build quickly because of the worms’ huge egg output. Barbers pole worms are large, blood-sucking worms which can quickly suck blood causing severe anaemia and rapid death in both sheep and alpacas. Haemonchus contortus The barber’s pole worm (BPW), Haemonchus contortus, is quite long (20 to 30 mm) and clearly visible. Only the adult female has the characteristic ‘barber’s pole’ appearance due to the pink (blood-filled) intestinal tract of the worm twisted around the paler reproductive tract. The male worm is smaller (around 15 mm) and pale pink. Females are prolific egg layers, laying up to 10,000 eggs per day. BPW eggs require warm, moist conditions to hatch. Once hatched, however, they develop into tough larvae that can survive for months on pastures before being ingested by grazing sheep or alpacas, where they then grow into blood-sucking adults. Adults can become arrested or inhibited inside the sheep for varying periods. They resume activity when environmental conditions become more favourable or when ewes have lowered resistance around lambing time. Clinical signs Because they are blood-sucking worms, clinical signs include: Anaemia Lethargy Failure to gain weight Submandibular oedema (bottle jaw) Collapse Death Diagnosis The only accurate way to diagnose worm infections before productivity losses have occurred is to conduct a worm test (worm faecal egg...

Warrnambool Veterinary & Apiam Animal Health

18 November 2015 Dear Warrnambool Veterinary Client, Since 1978 Warrnambool Veterinary has focused on providing the highest quality veterinary services for dairy, farm, equine and domestic pets on-farm and via our clinics based at Warrnambool, Koroit, Port Fairy and Nullawarre and is recognised as a leader in innovation, actively engaging the various levels of industry to continually improve and advance the level of service provided. Our clients’ needs and expectations are the motivating force behind our quest for continual improvement. To this end, the Directors of Warrnambool Veterinary have been in discussion with a number of very successful and well-regarded clinics across Australia about the potential to enter in to a mutually beneficial commercial agreement. The discussions have resulted in the formation of an entity, a publicly listed company, known to investors as Apiam Animal Health Ltd. The company will continue to be majority owned by the existing veterinary clinics’ directors. The aim of this company is to provide increased resources and infrastructure to support the individual practices that make up the group allowing them to do what they do now, but even better, and to grow and develop their services still further to meet the evolving needs of their clients. Under such a structure, the day-to-day management, culture, and operations of Warrnambool Veterinary will not change. Our service delivery will not change unless, of course, that change is for the better. The Warrnambool Veterinary name, logo, building and brand will not change. The only change will be our increased capacity to grow and refine our services to meet our clients changing needs, particularly across the dairy industry. The...
