In high-humidity tropical regions, broilers face severe metabolic challenges. When ambient temperatures exceed 32°C, the traditional cooling method—panting—becomes inefficient due to the high vapor pressure in the air.
Key Consequence: Metabolic energy is diverted from muscle growth to respiratory effort, leading to a significant spike in Feed Conversion Ratio (FCR).
Expert Insight: "Based on Tianrui’s 40 years of operational data, preventing heat stress is not just about bird survival; it is the primary driver of farm profitability."
To achieve the Wind-chill Effect required for large broilers, the house design must meet specific aerodynamic standards.
| Parameter | Recommended Standard | Why It Matters |
| Cross-sectional Wind Speed | 2.5 – 3.0 m/s | Removes boundary layer heat from birds >35 days. |
| Static Pressure Range | 15 – 25 Pa | Ensures fan efficiency and eliminates dead zones. |
| Roof Insulation (R-Value) | R-19 or Higher | Blocks up to 15% of solar radiant heat load. |
| Cooling Pad Thickness | 15 cm (High Evaporation) | Optimizes cooling efficiency in high humidity. |
In the Philippines, humidity is as dangerous as heat. A simple temperature-based controller is insufficient; you need a THI-based (Temperature-Humidity Index) system.
When relative humidity (RH) hits the 85% threshold, the intelligent controller must:
Deactivate water supply to cooling pads.
Maximize fan stages to increase air velocity.
Rationale: Adding moisture to saturated air stops birds from breathing out heat, creating a "sauna" that causes sudden mortality.
Compared to floor-raised systems, H-Type Automated Cages provide superior micro-environment control:
Vertical Airflow Uniformity: Multi-tier cages allow for even air distribution around every bird.
Ammonia Reduction: Automated manure belts remove waste daily, lowering house humidity and protecting respiratory health.
Is your target wind speed reaching 3.0 m/s for market-age birds?
Do your sensors calculate THI instead of just dry-bulb temperature?
Is your roof insulation preventing radiant heat transfer?
Conclusion: Mastering tropical broiler farming requires a bridge between biological needs and engineering precision. Tianrui Technology provides the proven expertise to ensure your flock hits target weights, cycle after cycle.
Managing heat stress in a tropical climate requires more than just equipment—it requires a partner who understands the biology of the bird and the physics of the house.
