In winter, the climate is dry and there are fewer infectious diseases, which makes it an ideal season for breeding rex rabbits. However, careful attention must be given to several key aspects of rabbit production during this time:
First, selecting high-quality breeding rabbits is essential. The quality of the parents directly impacts the health and growth of their offspring. For winter breeding, male rabbits should be between 7-8 months old and weigh at least 3.5 kg, while female rabbits should be 6-7 months old and weigh over 3 kg. Males should have a strong, well-proportioned body, with a flat back, agile movement, and sturdy legs. Females should be robust, calm, and well-developed, with at least four pairs of nipples. They should be able to pull fur to build nests, nurse their young, and avoid urinating in the nest.
Second, maintaining proper insulation and temperature control is crucial. Rex rabbits prefer a clean, dry environment with temperatures between 10°C and 25°C. During winter, the temperature should ideally be kept around 10°C, with a minimum of 5°C. If using heating, ensure good ventilation to prevent gas poisoning or respiratory issues.
Third, timely breeding is important. Due to cold weather, rabbits may become less active, making it easy to miss their estrus periods. Keep the temperature above 5°C and monitor the estrus cycle, which typically lasts 7–12 days, with estrus lasting 1–3 days. Breeding should be done on sunny afternoons when possible, or in the morning or evening if indoor temperatures are well-controlled.
Fourth, feeding and management require special attention. Winter is cold and short, so a nutrient-rich diet is essential. Green feeds like radishes, cabbage leaves, and carrots should make up at least 30% of the diet. For pregnant and nursing rabbits, feed them foods rich in vitamins and minerals, such as wheat bran, fish meal, and bone meal. Pellets can also be used, with a recommended formula: 15% corn, 15% soybean cake, 20% wheat bran, 8% lotus root, 35% grass powder, 2% bone meal, 0.5% salt, 0.5% vitamin additive, 1% shell powder, and 3% other ingredients. Young rabbits should be fed 4–5 times daily, including one meal at night. Ensure fresh water is always available and avoid feeding moldy, frozen, or soiled grass. After giving birth, females should be given brown sugar water or saline solution. Encourage exercise and disease prevention to improve survival rates.
Finally, disease prevention and treatment are critical. Regular disinfection and vaccination are necessary. Feeding garlic, onions, and green vegetables can help boost immunity. If any signs of illness appear, isolate the affected rabbits immediately, disinfect the area, and consult a veterinarian for prompt treatment.
