Our recently graduate Theethawat Uea-Anuwong published his research titled "Impact of Temperature-Humidity Index on Heat Stress Behavior and Welfare of Battery-Caged Yellow-Feathered Native Broilers During Summertime in Hong Kong: An Observational Study".
This observational study explored the impact of temperature-humidity index (THI) on heat stress behavior, hormonal responses, and body temperature in battery-caged yellow-feathered broilers on a Hong Kong poultry farm equipped with ventilation fans and foggers. Conducted in summer 2023, the research involved real-time THI measurement and assessments of heat stress behaviors, body temperatures, and serum corticosterone levels. The findings revealed that, despite the high temperatures, only 9.6% of the chickens exhibited significant heat stress behaviors, indicating that these native broilers possess a remarkable adaptive capacity to endure Hong Kong's hot and humid climate.
