This article focuses on the ventilation system of the high - efficiency H - type layer hen cages launched by Zhengzhou Livi Machinery Co., Ltd. Through scientific airflow organization (side - wall air intake + top air exhaust), a constant temperature and humidity environment is achieved, effectively preventing the impact of heat stress on the egg - laying rate of laying hens. The article deeply analyzes the key role of ventilation and temperature control technology in laying hen houses on laying performance. It combines the anti - corrosion effect of the aluminum - zinc alloy coating to extend the service life of the equipment and promote the stability of the farming operation. At the same time, it provides practical environmental detection methods and daily maintenance suggestions to help farmers improve egg quality and economic benefits, and assist laying hen farms in achieving efficient operation and sustainable development.
