Key recommendations

  • Shearing: June.
  • Best months for crias to be born: Jun–Sep (breed in Jul–Oct).
  • Heat precautions: rarely needed — still provide shade and water.
  • Barber pole worm season: Jun — run fecal egg counts every 4–6 weeks in these months.
  • Freezing nights: Oct–Apr — keep water from freezing.
  • Vitamin D for crias: Oct–Mar.
  • Grazing season: May–Sep (about 5 months); feed hay the rest of the year.
  • Meningeal worm: Meningeal worm is not established in this region.
  • 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.
