💡 Parasite Management Principles
- Barber Pole Worm (Haemonchus contortus): Highly prolific blood-sucker causing lethal anemia in small ruminants.
- Refugia Preservation: Leaving 20-30% of healthy low-egg goats untreated maintains susceptible worm genes in pasture, preventing total dewormer failure.
- Rotational Resting: L3 larvae decay over 30-40 days resting period, breaking the re-infection cycle before goats return.
