First, feeding principle
Rex rabbits are single-stomach herbivores and should be dominated by green coarse materials, supplemented by fine materials; general green coarse materials should account for 70-80 per cent of their total diet. The preparation of feed should be diversified and reasonably matched. When fed, regular dosing should be done, and less feeding should be added and drinking should be provided. Rex rabbits have a habit of quiet nights and they should be fed a rough feed at night. Keep rabbit houses clean and hygienic and try to create a quiet and comfortable living environment for them. The temperature is 25°C and the humidity is 55?-65? The density is based on the temperature and ventilation conditions. Under good ventilation conditions, 15-18 rabbits can be raised per square metre of rabbit cages.
Second, feeding measures
1. Nutrition supply. Rex rabbits have fast growth and development, and they should provide nutritionally comprehensive compound feeds, preferably pressed into pellets.
2. Timely grouping. After weaning, young rabbits should be reared in groups based on sex, age, and physical strength. Cage usually 4-5 per cage, captive generally 20-30 per group. Young male rabbits that are not used for seeding after weaning should be castrated. The male rabbits, breeding female rabbits, and non-clustered commercial rabbits should be kept in single cages.
3. Strengthen management. Kinds of male and female rabbit cages need to maintain a relatively long distance to avoid the opposite sex stimulation, affecting the male rabbit's sexual desire. Male rabbits are generally allocated at the age of 6-7 months and after maturation, with a maximum of 1-2 times per day and a rest period of 2-3 days for 1 day. Do not breed as much as possible during the hot season and during the moulting period. The pregnant female rabbit should be strengthened in nursing care, and should not be arbitrarily captured to prevent miscarriage. The litter box is prepared 2-3 days before the mother's labor, and the amount of concentrate feeding is reduced. The female rabbit must have enough water before delivery to prevent the female rabbit from losing water and thirst and eat puppies. Rabbits should be given good insulation and antifreeze work, and should be allowed to eat colostrum within 6 hours after birth. Feeding should be started at 16-18 days and weaned at 30-45 days.
Third, breeding breeding
Rex rabbits are estrus all year round, and can be used for breeding throughout the year. The fertility rate of mating female rabbits during estrus is high. Female estrus performance: loss of appetite, excitement, often forelimb box, hind legs, feet, look at the external reproductive organs can see the vulvar mucosa moist and moist. The mating method is usually artificially assisted in mating. The male and female rabbits are raised in separate cages. The maternal rabbit is placed in a female rabbit cage for breeding during estrus. After completion, the female rabbit is raised, and the rear buttocks are elevated. The hand tapped gently to prevent backflow of semen into the vagina of the female rabbit. Rabbits are stimulating ovulatory animals and females generally ovulate 10-12 hours after mating. The method of repeated mating or double mating using the same rabbit or another male rabbit for 6-8 hours in production can increase the conception rate and the number of litters.
IV. Disease prevention and control
The prevention of serious infectious diseases of rabbits should be prevented by vaccines in time. Normally, 2 ml of inactivated seedlings of Borrelia are injected subcutaneously into rabbits at 2-3 days of age. The rabbits are injected with 2 ml of rabbit lice vaccine at weaning, 2 ml of Poba is injected at 40 days of age, and rabbits and paps are injected at 60 days of age. Bacillus, Clostridium perfringens triple vaccine 2 ml. In the future, a rabbit lice vaccine or a rabbit triple vaccine is injected every 3-4 months. In addition to strengthening the feeding and management of rabbits and timely immunization, the use of drugs by groups to prevent diseases is one of the important measures for epidemic prevention. In particular, the use of safe, inexpensive and effective drugs, feed, drinking water, or additives for group prevention and treatment before or during the epidemic season can achieve significant results.
