This article explores effective methodologies for resourceful utilization of manure and comprehensive environmental risk management in large-scale laying hen operations. It provides an in-depth analysis of the H-type layer cage system integrated with automated manure removal and intelligent ventilation temperature control technologies. Covering the entire process from dry-wet separation to harmless treatment, the study aligns with ISO14001 standards to help farmers establish sustainable and eco-friendly farming practices. The implementation of these technologies not only enhances egg production efficiency and reduces environmental hazards, but also supports enterprises in obtaining international certification credentials. Combining practical guidance with forward-looking policy insights, this work serves as an authoritative resource for compliant and efficient poultry farming.
