The proper configuration of rabbit breeding equipment is a key factor in improving kit survival rates. The design of the farrowing box provides a suitable rearing environment based on the physiological needs of both the mother and kits. Breeding equipment mainly includes farrowing boxes, breeding cages, and kit isolation facilities. The farrowing box is a dedicated facility for the mother rabbit to give birth and nurse her kits, and its design directly affects the kit survival rate. The size of the farrowing box should match the mother rabbit's body size, and the internal space should allow the mother rabbit to enter and exit freely while preventing kits from climbing out. The bottom of the box should use a removable slatted floor for easy cleaning and disinfection, maintaining dryness and hygiene. The farrowing box should be lined with soft, absorbent, and insulating bedding, such as hay, shavings, or cotton wool, providing a warm and comfortable nest for the kits. A barrier or threshold should be installed at the box opening to prevent kits from climbing out and being unable to return, potentially leading to death from cold or starvation. The farrowing box can be hung outside the breeding cage or placed inside the cage for easy observation and inspection.

The design of breeding cages significantly impacts both the reproductive performance of doe rabbits and the survival rate of their kits. The cage dimensions should accommodate the doe's activity, feeding, drinking, and nursing needs. The cage floor should be made of plastic or galvanized wire mesh with appropriately sized openings to prevent kits from escaping. A resting platform should be provided inside the cage to offer the doe space while preventing her from trampling her kits. The location of the feed trough and water line should facilitate the doe's access to food and water while preventing kits from entering and contaminating the water. Breeding cages should be equipped with isolation facilities; if the doe exhibits biting behavior or refuses to nurse, she can be temporarily isolated for artificial nursing. For high-producing doe rabbits, a supplementary feeding area can be provided for kits after they begin eating solid food, offering dedicated feed to promote early development. Breeding cages should be easy to observe and operate, allowing caretakers to promptly identify problems and take intervention measures.

The impact of breeding equipment on kit survival rates persists throughout the entire lactation period. A well-designed birthing box can reduce mortality in baby rabbits due to cold stress, especially during cold seasons, as a well-insulated birthing box can significantly improve the survival rate. A dry and hygienic birthing box reduces bacterial growth and lowers the incidence of common newborn rabbit diseases such as yellow urine disease and E. coli infection. A well-designed breeding cage can reduce accidents where the mother rabbit tramples her kits, especially for first-time mothers and inexperienced does; a reasonable cage layout can reduce accidental mortality. Isolation facilities provide emergency treatment space when the mother rabbit is sick or exhibits abnormal behavior, ensuring the safety of the kits. Easy-to-clean breeding equipment improves hygiene management efficiency and reduces the risk of disease transmission. Through scientific configuration of breeding equipment and meticulous design of birthing boxes, rabbit farms can significantly improve the survival rate of baby rabbits, increase the number of rabbits sold, and enhance breeding efficiency.
