El Niño events alter temperature and humidity patterns, affecting energy use in poultry houses. In temperate zones, unexpected cold spells increase heating demand, raising carbon emissions. Subtropical farms face longer hot periods, intensifying ventilation and cooling pad operation, which spikes electricity consumption. Tropical regions experience extreme humidity, forcing fans and dehumidifiers to run longer.
These shifts increase the carbon footprint by 15–30% during El Niño years compared to neutral years. To mitigate this, energy‑efficient climate control systems—such as variable‑speed fans and solar‑assisted cooling—can reduce grid dependency. Installing photovoltaic panels and biogas recovery from manure further lowers net emissions. Adaptive management, including real‑time energy monitoring and predictive control, helps farms maintain low carbon intensity despite climate variability.

A New Era of Human‑Machine Collaboration: Challenges and Solutions for Deploying AI Decision Systems in Floor‑Rearing Farms
Deploying AI decision systems in floor‑rearing farms promises improved efficiency but faces practical hurdles. Three major challenges emerge: data infrastructure gaps, worker acceptance, and system maintenance cost. Many farms lack reliable sensors or stable internet, leading to incomplete data. Workers, accustomed to manual observation, often distrust AI recommendations. Solutions include phased deployment starting with basic…

Variable-Frequency Fans and Multi-Stage Cooling Linkage Control: Response Mechanism of Smart Environmental Control Systems to Extreme Heat
Extreme heat events threaten poultry health and productivity. Smart environmental control systems employ variable-frequency fans (VFFs) and multi-stage cooling linkage to respond effectively. VFFs automatically adjust speed based on real-time temperature, providing low airflow during mild heat and maximum speed during heatwaves. This saves energy while maintaining bird comfort. Multi-stage cooling activates sequentially: first, tunnel…

Synergistic Optimization of Cooling Pad Expansion and Water Quality Management: Strategies for Improving Evaporative Cooling Efficiency in Hot and Humid Regions
In tunnel-ventilated poultry houses, evaporative cooling pad performance directly impacts bird welfare and productivity during summer. Two critical factors determine system effectiveness: proper pad sizing and water quality management. Pad Sizing Principles Pad area should be determined by total tunnel fan capacity, not house dimensions. Industry standard recommends one square foot of six-inch pad for…

Equipment Depreciation and Technology Iteration: A Lifecycle Cost Analysis Model for Automated Floor Rearing Systems
Automated floor rearing systems require a lifecycle cost perspective beyond initial purchase price. Depreciation—spreading equipment cost over its usable life—and technology iteration—rapid upgrades in sensors, controls, and software—shape total ownership expense. A robust analysis model includes five phases: acquisition, installation, operation, maintenance, and residual value. Shorter technology cycles (e.g., every 3–5 years) accelerate depreciation but…
