Key recommendations

  • Shearing: May.
  • Best months for crias to be born: May–Jun (breed in Jun–Jul).
  • Heat precautions: Jul–Aug.
  • Barber pole worm season: May–Sep — run fecal egg counts every 4–6 weeks in these months.
  • Freezing nights: Nov–Apr — keep water from freezing.
  • Vitamin D for crias: Oct–Mar.
  • Grazing season: May–Oct (about 6 months); feed hay the rest of the year.
  • Meningeal worm: Meningeal worm (carried by white-tailed deer) is established in this region and is a leading cause of neurological disease in alpacas. Talk to your vet about a prevention plan for the snail season.
  • Selenium: Soils and hay in this state are often selenium-deficient. Use a camelid mineral formulated for low-selenium areas and blood-test a few animals each year.
