French original rabbit breeding management technology

Rex Rabbit, also known as the Rex Rabbit, is a rare animal with skin and flesh that is produced mainly in the world and has high meat-producing performance. Feeding management techniques are as follows: First, the diet is mainly grass, pay attention to the crude fiber level, the rabbit is a herbivores, the level of crude fiber in the adult rabbit diet can reach 14%, the young rabbits that have been weaned should be lower, generally 8% -10%. Crude fiber is very important for Rex rabbits, and can maintain the normal density of gastro-intestinal chyme, control the normal passage of digestive tract and the normal formation of hard feces, protect and maintain the healthy state of intestinal mucosa. Longer feeding of low-fiber diets will cause abnormal changes in the mucosal structure of the digestive tract, and growth of young rabbits will be slow. Feeding too much concentrates such as cereals, cakes, or soy beans can reduce the content of crude fiber and make the rabbit's cecum and colon burden too heavy. This can lead to a steady imbalance of the normal flora in the cecum and a large proliferation of harmful bacteria to produce toxins. Gastrointestinal disease occurred rapidly and died. Second, supplement concentrates, obtain energy and protein, protein is the life foundation of rabbits, is the most important nutrient substance in the whole life activity. The soft and luxuriant hair is formed by the keratinized protein. Rex rabbits must obtain energy and essential amino acids from supplemental concentrates to synthesize body proteins and form new rabbit somatic cells and tissues, such as muscles, nerves, internal organs, remarks, and fur. Practice has proved that in the late pregnancy and lactation, the protein level in the diet increased to 16% - 18%, an increase of 0.3 methionine and lysine, can improve the survival rate of weaning rabbits and weaning weight. For weaned young rabbits, the protein level in the diet should be 15% - 16% to ensure the growth and development of young rabbits. 2% - 3% of high-quality fishmeal or MBM in the diet formula can promote the growth of young rabbits and improve the quality of plush. When there is a lack of protein in the diet, the rex rabbit hair can be sparse, the strength of the wool fibers can be delayed and the hair can be changed slowly, the growth can be slow, the body size can be thin, and the skin area can not be graded. Can also be male rabbit sperm solvate quality is poor, do not match the species; female rabbits are not estrus, refused to match or difficult to pregnancy, the number of fetal deaths during the late pregnancy increased, the weak production, the female rabbit lack of milk. However, high energy and protein are also harmful, which not only results in feed wastage, but also infertility after female rabbits' sauce. In severe cases, it can cause diarrhea death. Third, the cage construction, rabbit house should be built at a high place, choose to sit south and south is appropriate. The rabbit house should be kept dry with a relative humidity of 60% and no more than 50% in winter. Ventilate well, but avoid drafts. In winter, the humidity in adult rabbithouses can be maintained at about 10°C in order to breed normally. Light hours are best in the 14-16 hours, too long or too short have an impact on the breeding of female rabbits. Rex rabbits are raised in single cages, and the group raises each other and tears the skin. The floor of the cage is required to be flush, the leakage of urine is good, and the excrement and urine contamination are avoided. Rabbit cages are 75--85 cm long, 60--70 cm deep and 40--45 cm high. The cage floor of the third floor should not exceed 1.5 meters above the ground. Fourth, disease prevention and control, Rex rabbits have weak resistance to many pathogenic microorganisms and are vulnerable to infringement. Rabbits should be cleaned every day and regularly sterilized. It is best to sterilize the cage with a flame torch. Do not disinfect it with a liquid to avoid excessive humidity in the room. In order to prevent the occurrence of coccidiosis in young rabbits, drugs should be used to repel 5 days before weaning. Chlorpheniramine 10 mg/day/only; later increase with age, to 20 mg/day when the body weight reaches 1250 g Only, and follow the instructions to take. In order to prevent rabbits, rabbits can be given 1 to 1.5 ml rabbits vaccine intramuscularly every time they are weaned, and once again at 60--65 days of age, with a dose of 2 ml; they are immunized once every 4 to 5 months. To prevent pasterellosis, Pasteurella vaccine should be immunized every 3 months. In addition, male and female rabbits suffering from conjunctivitis and infectious rhinitis are strictly prohibited from participating in breeding when selecting the species.
