• Barber’s Pole Worm in Alpacas

    The gastrointestinal parasite Haemonchus spp. is better known as the barber’s pole worm (BPW) because the adult female worm has a white tubular uterus that winds around their blood-filled tubular gut, giving the look of a barber’s pole (Figure 1). This parasite is a blood sucker of domestic livestock, causing anaemia and illthrift and can kill alpacas (and sheep, cattle and goats) quickly and in high numbers. more »
  • Alpaca Parasites

    Alpacas and llamas are susceptible to many of the gastro-intestinal nematodes or “worms” that infect sheep and cattle, including barber’s pole worm (Haemonchus spp) and the scour worms. The behavior of worms in alpacas is not well described and is currently being studied at the University of Melbourne. The project is identifying worm species, worm behaviour, methods of diagnosis/monitoring of worm burdens and worm control in alpacas. In the interim, camelid farmers need to extrapolate from sheep research on how best to control worms. more »
  • Husbandry: Worms And Alpacas

    Alpacas are susceptible to cattle, goat and sheep worms, however the four most likely to cause problems with alpaca are: Barber’s Pole Worm (Haemonchus contortus) up to 10,000 eggs per day Small Brown Stomach Worm (Ostertagia ostertagi) 100-200 eggs per day Black Scour Worm (Trichostrongylus spp) 100-200 eggs per day Liver Fluke (Fasciola hepatica) 20,000-50,000 eggs per day The eggs are passed out in the faeces and can remain in the paddock for long periods, until warm moist conditions are present and they begin to hatch into infective larvae. Alpacas with a worm burden can be passing eggs in their faeces over winter with the eggs not hatching due to the cold, only to have millions of eggs begin hatching when the warm spring days arrive. This sudden arrival in the paddock of millions of larvae can result in sudden and severe worm infestations with severe consequences. more »

  • Drug Resistant Worms: Anthelmintic Resistance is a Growing Concern for Alpaca Owners

    Scientists from the University of Georgia College of Veterinary Medicine evaluated 32 privately owned camelid (16 alpaca and 16 llama) farms in the southeastern United States to determine if anthelmintic (dewormer) resistance was evident in the Haemonchus contortus (barberpole worm) populations on these farms. more »
