Key recommendations
- Shearing: April.
- Best months for crias to be born: Apr–May (breed in May–Jun).
- Heat precautions: Jun–Aug.
- Barber pole worm season: Apr–Oct — run fecal egg counts every 4–6 weeks in these months.
- Freezing nights: Dec–Mar — keep water from freezing.
- Vitamin D for crias: Nov–Feb.
- Grazing season: Apr–Oct (about 7 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.
