Second, the choice of rabbits. After the plan is determined, good breeds should be selected according to production conditions and needs.
1, determine the introduction of the number: as a species of rabbit farms, the general introduction of a variety of 15 varieties of breeding male rabbits and 80 families of female rabbits, while the coat color should not be too much. The number is too small, prone to inbreeding, resulting in degradation, affecting the quality of rabbits. For individual rearing, rabbits of different kinships should be selected for breeding in rabbit farms.
2. Select individuals: According to the biological characteristics and performance indicators of the species, choose the best ones. With reference to the pedigrees and records, select rabbits with good heredity, no defects, high productivity, good health, and excellent appearance. 6 months old body weight more than 3 kilograms, pure color, color, smooth, rich, smooth, good elasticity, no bite, no pollution, hair length between 12-22 cm. The male rabbits pay attention to the symmetrical development of the testicles to prevent the testis, and the testis of 3-4 months old drops to the scrotum. Female rabbits pay attention to the development of the genitals and the number of nipples. The number of nipples is generally 3-5 pairs.
3, the timing of introduction. Rex rabbit introduced from the origin to the production field, temperature, humidity and other environmental factors are very different. In addition, in the transportation process, because drinking water and feed are not supplied in time, the rest is not good, and it has an adverse effect on the organism, which easily triggers the stress response of the organism and often causes diseases and death. In order to reduce the occurrence of such phenomena, attention should be paid to the choice of timing.
Rex rabbits have strong adaptability to dry and cold areas, and have strong adaptability in the same latitudes, and poor adaptability from low temperature and low humidity areas to high temperature and high humidity areas. Therefore, the introduction season should be selected in the spring and autumn season. Usually introduced from cold regions to temperate tropical regions should be carried out in the spring, and from the tropical temperate regions to cold regions should be carried out in the fall.
The adaptability of Rex Rabbit to the new environment is also related to its own situation. Young Rex rabbits have a strong adaptability to the environment when they are weighed between 1.5 and 2 kg at the age of 3-4 months, and they are the best months of introduction. In general, the bigger the weight, the better.
Third, prevent the introduction of the disease. At present, various types of rabbit farms have certain epidemics in some cases. If they do not pay attention, they will also bring in diseases and affect production. Therefore, introducing rabbits from a healthy and disease-free breeding farm should be done at the same time as quarantine and immunization.
For puppies, the diseases that require quarantine include: rabbit viral hemorrhage, clostridium welchii, rabbit syphilis, infectious rhinitis, subcutaneous abscess, epilepsy, foot dermatitis, and coccidiosis.
For some diseases that can be vaccinated, temporary immunizations are performed 1-2 weeks prior to transport. For diseases that are not protected by vaccines, they are fed with oxytetracycline or sulfa drugs at a concentration of 5% for 5 days before transportation to prevent bacterial diseases; they are fed with a concentration of 60 mg/L of chlorophenylphthalein, Prevention of coccidiosis. At the same time, a large amount of vitamin C supplementation, vitamin E supplementation and trace element selenium in order to relieve stress.
Fourth, strengthen management during the transportation process. According to the mode of transportation and the length of time, prepare sufficient drugs, feedstuffs, and cages, and thoroughly disinfect the cages and vehicles before shipment.
Rex rabbits should not be too crowded. There should be 2/5-1/2 activity places in the cage to prevent overcrowding and excessive sweating. It is best to use a single cage. Three cages per cage can be placed closer to each other and no more than four can be placed. The same weight and size are required to be placed in a cage so as to avoid crushing and crushed.
Rabbits should eat and drink before they start their journey. The fortune should be within 24 hours and they should not be fed halfway. For more than 24 hours, physical exertion is heavy, and midway should be properly rested, fed with water and supplemented with physical fitness. The green feed is best, but not eat too much, otherwise the transport is bumpy and prone to injury. Usually put some potatoes and carrots in a rabbit cage to reduce the energy consumption. If you stop for a few days, remove the rabbit and rest in a spacious place. Each rabbit has an area of ​​4-5 times smaller than its own area, and is bred by small groups in a short period of time, carefully managed to prevent disease.
During the train transportation, the on-duty personnel checked day and night to record the temperature and humidity of the carriages so as to prevent changes in the cracks and provide adequate drinking water and supplementary feeding.
No matter which method you use for transportation, you should pay attention to keeping warm in winter and preventing heat in summer. Special care is given to rabbits with depressed spirits, loss of appetite, and physical weakness. If necessary, rehydration, ear vein or intraperitoneal injections of glucose and vitamin C are given to improve the body condition.
Fifth, management after shipment. When the rabbits are shipped back in summer, they are placed in a cool, dry place, in winter, in a warm place, rested for a while, and then raised in a single cage or small group. Attention should be paid to placing individuals of similar physique and body weight together. The first time drinking water to add a small amount of sugar, salt and 0.1% potassium permanganate, and then feed a small amount of green onions or garlic to achieve the purpose of sterilizing and supplementing body fluids. Gradually feed the half-dried green feed, hay and a little concentrate and feed on eight-point full. Never feed a large amount of concentrate.
After returning, if rabbits originally existed, the newly introduced rabbits should be kept in isolation for one month for a thorough examination. They are indeed healthy and disease-free before they can be reared in groups. In the case of morbidity and death, immediately identify the cause. If it is an infectious disease, it should be timely isolated and disinfected; if it is an ordinary disease, it should be promptly treated to reduce economic losses. The lean rabbits should be fed separately and rehydrated in time.
