Abstract

Background: Broiler chickens are fast-growing poultry that require optimal housing environmental conditions to support growth performance and production efficiency. Closed house systems are designed to control temperature, humidity, and ventilation. However, external environmental factors, such as the presence of tree shade, may influence the internal microclimate of the house, particularly by reducing heat exposure from direct solar radiation. Purpose: This study aimed to compare the microclimate conditions (temperature and humidity) and body weight of broiler chickens reared in closed house systems with and without tree shade. Methods:The study was conducted for 35 days in two closed house facilities, each housing 9,000 broiler chickens. Temperature and humidity were recorded daily, while body weight was measured at 35 days of age by randomly sampling 30 chickens from each house. Temperature and humidity data were analyzed using the Mann–Whitney test, whereas body weight data were analyzed using the Independent Sample T-test at a 5% significance level. Results: The average temperature and humidity in the shaded house tended to be lower than those in the unshaded house, although no statistically significant differences were observed. In contrast, broiler chickens reared in the shaded house exhibited higher body weight compared to those in the unshaded house. Conclusion: The presence of tree shade in closed house systems contributes to creating more favorable microclimate conditions and supports increased body weight in broiler chickens.

Abstract

This study examines microclimate fluctuations in a closed-house system for tropical broiler chickens and their relationship with broiler production performance under an Internet of Things (IoT)-based environmental control system. The system was implemented to monitor, record and regulate environmental parameters in real time to support environmental stability under tropical conditions. The relationship between Effective Temperature (ET), Temperature-Humidity Index (THI), Heat Stress Index (HSI), and Performance Index (PI) of broiler chickens was evaluated using non-linear curve fitting and Spearman’s correlation analysis based on data generated by the IoT. The results indicate that the quadratic model provides a better fit than the linear model in describing the relationship between microclimate variables and PI, although most models were not statistically significant. ET showed the highest explanatory power (R² = 0.164; p = 0.068), followed by THI (R² = 0.096; p = 0.220), whilst HSI showed almost no relationship with PI (R² = 0.010; p = 0.862). Spearman’s correlation analysis indicated that ET had the strongest and most significant negative correlation with PI (? = ?0.526; p = 0.002), followed by THI (? = ?0.490; p = 0.004), whilst HSI was not significantly correlated with PI (? = 0.228; p = 0.202). These findings suggest that ET and THI are more closely associated with broiler performance than HSI under tropical closed-house conditions. The final PI value (417.69) exceeded the overall average PI (358.29), indicating relatively stable production performance despite fluctuations in the microclimate.
