How to prevent the degeneration of Rex rabbit breeds

To establish a complete pedigree file for newly introduced breeds of rabbits, first establish pedigrees, and group numbers to establish breeding cards, so that the records of mating and birthing records are clear, so that the blood of rabbits is clear and inbreeding is avoided. At the same time, strictly control the initial allocation time, general male rabbits need 7 months to 8 months, female rabbits 5 months to 6 months, weight 2.5 kg to 3 kg or 85% of adult weight can be, the ratio of male to female 1:4 or 1:8; breeding intensity for male rabbits once or twice a day, for 2 days to 3 days, rest 1 day, to prevent premature aging of male rabbits.
The best matching model for the rational selection of rex rabbits is young male rabbits; female senior male rabbits; young male rabbits; female rabbits; young male rabbits; excellent female rabbits must be mated with excellent male rabbits. The quality of male rabbits is higher than that of female rabbits. Avoid early-matching and blood-matching and prohibit mating by close relatives. Only good breeders breed high-quality offspring to produce high-quality fur.
The practice of scientific breeding and selection of rex rabbits not only looks at the appearance characteristics and production performance of the male and female rabbits, but more importantly whether the production performance of their offspring is excellent. The key is the richness, flatness and fineness of the coat. Good varieties still need good law, only scientific management and breeding can produce high-quality products, the protein content of the mixed feed should be more than 16%, digestible energy per kilogram content of 2500 kcal, crude fat 2% to 3%, coarse Fiber 12% to 14%, tungsten 1%. Rabbits have a monthly weight gain of 500 grams to 600 grams, and their growth is in line with fur quality standards. Excessive growth results in thin, thin skin that affects the quality of the skin. Slow growth can affect growth and effectiveness.
Establish a healthy rabbit population to carry out planned immunization and drug prevention for rabbit populations, and create conditions for the establishment of healthy and reproductive rabbit nucleus populations, and regular quarantine and deworming of the core group of male rabbits to eliminate diseased rabbits and carriers in time Rabbits to breed a healthy and high quality rabbit population.
