How to prevent the degeneration of Rex rabbit breeds

To create a comprehensive pedigree file for newly introduced rabbit breeds, it's essential to first establish clear lineage records and assign group numbers to maintain breeding cards. This ensures that mating and birthing records are well-documented, allowing for precise tracking of bloodlines and preventing inbreeding. Additionally, the initial breeding age should be strictly controlled—male rabbits should be at least 7 to 8 months old, while females should be between 5 to 6 months. The weight should be between 2.5 kg to 3 kg or about 85% of their adult weight. The male-to-female ratio is typically 1:4 or 1:8. Breeding intensity for males should be once or twice daily for two to three days, followed by a rest day to avoid early aging. When selecting breeding pairs for Rex rabbits, the ideal model involves pairing young males with older females, or young males with experienced females. It's important to ensure that only high-quality females are bred with top-tier males, as the quality of the male often has a greater impact on offspring quality. Early mating and inbreeding must be avoided, and close relatives should never be mated. Only superior breeders should be allowed to reproduce in order to produce high-quality fur. Scientific breeding and selection go beyond just looking at the physical traits and performance of the parent rabbits. More importantly, the performance of their offspring must be evaluated. The key indicators are coat density, smoothness, and fineness. Even the best varieties require proper management. Scientific breeding practices combined with good nutrition are essential for producing high-quality products. Feed should contain more than 16% protein, 2500 kcal of digestible energy per kilogram, 2–3% crude fat, 12–14% crude fiber, and 1% ash. Rabbits should gain 500–600 grams per month, with growth aligned with fur quality standards. Overly rapid growth can lead to thin skin, which negatively affects fur quality, while slow growth may reduce productivity and efficiency. Establishing a healthy rabbit population involves implementing planned vaccination programs and medication prevention. This helps create conditions for a strong, reproductive core population. Regular quarantine and deworming of the core group of male rabbits is essential to identify and remove sick animals and carriers promptly. By maintaining strict health protocols, breeders can develop a robust, high-quality rabbit population.
