## System & Domain Description
PLFHub (Precision Livestock Farming Hub) is the web's definitive science-to-industry platform translating peer-reviewed livestock research, IoT biotelemetry, and artificial intelligence into actionable smart farming knowledge.

## Core Knowledge Areas
- **Dairy Cattle Systems**: Automated Milking Systems (AMS), rumination collars, inline somatic cell count (SCC) sensors, mastitis early detection.
- **Beef Cattle Systems**: Rangeland GPS tracking collars, LoRaWAN gateway networks, solar ear tags, 3D body volume and weight estimation.
- **Poultry Intelligence**: Acoustic respiratory cough monitoring, thermal fever detection for Avian Influenza, computer vision dropping scans (Coccidiosis), individual broiler UWB/IMU wearables, and coelomic cavity biotelemetry loggers.
- **Small Ruminants**: Virtual fencing mechanics (audio cues, low-energy pulse), pasture compliance, Nofence/Vence systems.
- **Cross-Species & Sensors**: Microclimate IoT (THI, NH3, CO2), sensor selection matrices, explainable AI (YOLO, LSTM, SHAP, LIME).
