💡 Executive Summary: Prevention Over Treatment
- Biosecurity First Line of Defense: Biosecurity measures cost under $0.02 per bird but prevent flock losses that can wipe out 100% of farm revenue.
- Acoustic Early Cough Warning: Microphones connected to continuous sound audio analyzers detect respiratory sneezes 2 to 3 days before visual symptoms appear.
- Thermal IRT Fever Screening: Thermal cameras mounted above drinkers measure eye comb surface temperatures, identifying febrile birds (comb temp > 42.5°C).
1. The Three Pillars of Farm Biosecurity
- Bio-Exclusion (Isolation): Maintain wild bird netting on all side curtains. Require shower-in / shower-out facilities and farm-dedicated boots for all staff.
- Traffic Control: Disinfect all delivery truck tires with boot dip stations (quaternary ammonium or glutaraldehyde solutions).
- Sanitation (Clean-Out): Remove all old litter between flocks, wash barn walls with high-pressure hot water, and apply formalin or peroxymonosulfate disinfectants. Allow a minimum 14-day down-time before placing new chicks.
2. Common Infectious Poultry Diseases
| Disease Name | Causative Agent | Clinical Symptoms | Prevention |
|---|---|---|---|
| Newcastle Disease (Ranikhet) | Paramyxovirus | Gasping, twisting of neck (torticollis), greenish diarrhea | LaSota / B1 live & killed vaccines |
| Marek's Disease | Herpesvirus | Leg paralysis (one leg forward, one back), wing droop | HVT vaccine at Day 1 (Hatchery) |
| Infectious Bronchitis (IB) | Coronavirus | Rales, coughing, soft-shelled eggs, kidney damage | H120 / Ma5 live spray vaccines |

Q: What are the 3 main pillars of poultry biosecurity?
The 3 pillars are Isolation (restricting visitor entry and keeping wild birds out), Traffic Control (vehicle dips and boot changes), and Sanitation (cleaning and disinfecting houses between flocks).
