The scientific configuration of a rabbit housing environmental control system is a fundamental condition for ensuring the healthy reproduction of rabbits. Its components and operating parameters need to be carefully designed based on the biological characteristics of rabbits. The rabbit housing environmental control system mainly includes a temperature regulation system, a ventilation system, a humidity control system, and a lighting control system. The temperature regulation system provides heat in winter through underfloor heating, hot air furnaces, or heat lamps, and lowers the housing temperature in summer through fans, wet curtains, or misting systems. The suitable temperature range for rabbits is 15 to 25 degrees Celsius. Breeding rabbits are more sensitive to temperature changes; both excessively high and low temperatures will affect their reproductive performance. The ventilation system maintains fresh air in the housing through negative or positive pressure ventilation, promptly removing harmful gases such as ammonia and carbon dioxide, and providing sufficient oxygen. The ventilation volume in the rabbit housing needs to be adjusted according to the season and rabbit density. In winter, minimum ventilation should be maintained while ensuring warmth, while ventilation and heat dissipation need to be increased in summer.

The operating parameters of the rabbit housing environmental control system need to be adjusted according to the different physiological stages of the rabbits. Pregnant does have high environmental requirements, necessitating stable temperatures to prevent stress that could lead to miscarriage or fetal maldevelopment. Lactating does and kits require higher ambient temperatures. Newborn kits, lacking fur, have poor thermoregulation and need a localized temperature of around 30 degrees Celsius. Growing rabbits are more cold-resistant, but drastic temperature fluctuations still need to be prevented. The ideal relative humidity in rabbit hutches is 50% to 70%. Excessive humidity promotes bacterial and parasite growth, leading to respiratory and digestive diseases; insufficient humidity increases dust, irritating the respiratory tract. Light plays a crucial role in regulating rabbit reproductive activity. Breeding rabbits require 14 to 16 hours of moderate light daily to enhance libido and conception rates; fattening rabbits can benefit from reduced light and a quiet environment to promote growth.

The environmental control system plays a vital role in ensuring healthy rabbit reproduction in several ways. Stable temperature and humidity conditions reduce stress responses, lower the incidence of respiratory and digestive diseases, and increase survival rates. Good air quality reduces the irritation of ammonia to the respiratory tract, protecting the health of rabbits and improving the working environment for farm staff. Proper ventilation design regulates airflow speed within the sheds, preventing drafts from directly hitting the rabbits and avoiding diseases such as colds and arthritis. Light control regulates the sexual activity rhythms of breeding rabbits, improving estrus efficiency and litter size. In hot seasons, cooling facilities effectively prevent heat stress-induced infertility, abortion, and decreased feed intake, maintaining normal reproductive performance. Through the scientific operation of the environmental control system, rabbit farms can achieve balanced breeding throughout the year, improving the utilization efficiency of breeding rabbits and the survival rate of kits, providing a reliable guarantee for large-scale rabbit farming.
