Risk Factors to Control
🌧️ Moisture & Sanitation
Wet, contaminated environments allow oocysts to sporulate and become infectious. Keep areas dry and clean.
👥 Overcrowding
High stocking densities increase fecal-oral transmission and stress animals, making them more susceptible.
😰 Stress Events
Weaning, transport, weather changes, and diet shifts suppress immunity and trigger outbreaks.
🆕 New Arrivals
Mixing age groups or introducing new animals without quarantine brings new Eimeria strains.
Preventive Medication Strategy
During high-risk periods (brooding, weaning, transport), consider low-dose amprolium in water (50-65 mg/kg) to control parasite load while allowing immunity to develop. Consult your veterinarian for species-appropriate protocols.
