Timely construction of field training and comprehensive ability From the perspective of market environment, breeding is the most extreme form of peak construction, low-level slaughter; from the internal environment, the field facilities to meet the needs of rabbits, the quality of the introduction of rabbits, feeding and management What is the level, whether it is good at absorbing advanced feeding and management techniques, whether it is good at adjusting the scale of deposits and withdrawals according to the market situation; from the perspective of personal qualities, is there interest in keeping rabbits and perseverance, whether timely summing up the practical experience and lessons in breeding, can we If you don't fear the dirty, tired and tired, you will have a certain influence on the rabbit's results. Good varieties can be sold at a good price. High-quality varieties are fundamental to producing good skin. 1. Do not deal with speculators and traders. 2. The introduction season is appropriate for spring and autumn. The number of introductions will depend on the preparation of the site, funds, technology, feed, etc. Should not lead young rabbits, should be cited more than 5 pounds to be produced in rabbits, male rabbits than females 2 to 3 months. 3. The standard for purchasing rabbits (1) is short: 1.6 to 1.8 cm in length. Biping: The surface of the coat is smooth. Three dense: excellent species density of 1.6 ~ 38,000 / square centimeter, in practice, the mouth with rabbit hair whirlpool, exposing the tip of a large skin is appropriate, too large for the degenerative species. Four prison: fluff is not easy to fall off, tough quality. In addition, the thickness of the double skin can be measured with a vernier caliper, preferably 3 mm. (2) Five checkpoints: A thin and thick old neck. The second touch, touching the spine to look fat, touch the breast and abdomen. Three overcast pussy and toes. Four squeezed feces to see digestion. Five throw rabbits to see all fours. Choose a venue to build a rabbit house 1. Site moisture pollution prevention. Choose a place with high dryness and leeward sunshine, there are no pollution sources and noise sources around, and the water source should be running water, well water and other live water. 2. Rabbit house ventilation heavy insulation. Before entering rabbits, deal with walls, floors, doors and windows to facilitate disinfection and winter warmth and summer ventilation. According to the survey, it is better to use a rabbit's incubator to warm up the fire. There should be no coal stoves in the house. The new facility is concerned with the ease of use of heating equipment. 3. Rabbit equipment. (1) The warmth, ventilation, size and shape of the production box, the mat grass in the production box, and the placement position of the production box all have a great influence on the survival rate of the pups. (2) Rabbit cages. In general, cement boards and bricks are used to build bricks. Three layers are placed on top and bottom. Rabbit cages, young rabbit cages, and fattening cages are divided. The rabbit cage must first prevent the bunnies from escaping from the cage slits or the troughs to cause mixed litters or death. Secondly, the cage bottom plate should be made into the front plate and be leaked after sewing. The first half should be glued and the latter half should be slatted. This will not only control foot dermatitis but also be hygienic, and it will also reduce feed wastage. (3) Feeding tanks shall be self-sealing automatic feeding troughs. The problems in the use of feed for high-quality animal feed concentrate households mainly include the following points: 1. The market is low in nutrients, and good breeds feed poor quality hides. 2. The size of a material to eat, nutrition is a waste of high, low breeding rabbits, young rabbits live longer and slower. 3. Hubu is unscrupulous and unscientific. The quality of multi-dimensional Feed Additives on the market is uneven, and the purchase of full-priced materials is costly and prone to overexpiration. 4. Antibacterial materials mixed in the material, many rabbit farmers to terramycin and other broad-spectrum antibiotics as ingredients must be added, resulting in recalcitrant intestinal flora imbalance, and easy to produce drug resistance, lay the hidden dangers for the prevention and treatment of epidemic diseases. In this regard, the following improvement measures are proposed: 1. Purchase premixes or concentrates for rex rabbits produced by regular manufacturers, and purchase raw materials such as corn, soybean meal, and grass powder that are easy to grasp, and follow the different stages of young rabbits, female rabbits, and young rabbits. With full price material. 2. Prevent mildew. In particular, the mildew of grass powder is frequent and harmful, and many rabbit farmers have suffered serious losses. It is recommended to store raw materials as much as possible and to process it by themselves. 3. Minimize antibacterial drugs as much as possible, and use Additives such as allicin and probiotics that are beneficial to the balance of intestinal flora. Reducing Breeding Ratio of Male Rabbits and Engaging in Artificial Insemination At present, most rabbit farms sell rabbits in a ratio of 1:2 to 3 for males and females, but actual production can be 1:8, and artificial insemination can be as much as 1:25, which reduces the number of rabbits. Feeding costs increase the utilization rate of high-quality male rabbits, so that net income can increase by more than 30%. Therefore, poor quality male rabbits should be eliminated in a timely manner in production, and artificial insemination should be carried out as soon as possible in large-scale farms or regions in order to expand quality public health. Rabbits cover and reduce the incidence of reproductive diseases. Key measures to increase the survival rate of puppies The scientific feeding and management of puppies is very important for raising the economic benefits of raising rabbits. Specifically, there are five key measures: 1. Early feeding of colostrum, regular feeding, feeding full milk. The rabbit must have colostrum within 6 to 10 hours after birth and should not be forced to breastfeed. If there are mastitis in mothers with multiple births or female rabbits, foster them in time. 2. Keep warm and cold. The female rabbit usually gives birth at night, and it is prone to death in the whole nest in winter. It is necessary to do a good job of confinement, and prepare the farrowing box and the insulation room. Keep at room temperature 15 °C ~ 25 °C. Throughout the entire lactation period, mothers are separated and reared and fed regularly. 3. Look at the rabbit and raise the rabbit. Note that according to the growth of the pups, the female rabbit's feed formula and the proportion of green materials are adjusted. In the summer and autumn season, 2 to 3 pounds of green material is fed per rabbit, and 1 to 2 of the concentrate is mixed, and the hay is fed for 3 to 6 winter and spring festivals. Two, juicy feed 4 to 6 two, fine material 1 to 2 two. In order to prevent mastitis and enteritis in pups, one-needle urea should be injected on the day of the laying of the female rabbit, 0.5 ml each. 4. Late feeding, early repellent. In order to prevent indigestion, from the 12th day after the puppies were fed, the supplementary feeding was changed to 18 days after the supplementary feeding. The main diet was concentrated feed and less meals were fed, and the food was added to the maternal diet to promote digestion. On the 25th, he will feed green, but he will not be able to feed vegetables. The pups were 30 days old and each rabbit was injected with 0.05 ml of Invitrogen to prevent parasite diarrhea. 5. Weaned off the good puppies. Generally weaned at 30 to 35 days of age. Weaning adopts the method of not leaving the nest, grouping, keeping feed, and keeping the environment intact, so as to avoid the stress response of weaning rabbits. Reasonable disease prevention does not indiscriminately rule 1. Prevention is heavier than treatment, and it does not chaos. That is, it is not advisable to add broad-spectrum antibiotics in feeds for a long period of time, minimize oral prevention and treatment, and focus on scientific rearing to improve the physiology of rex rabbits. 2. Timely immunization against 40 days and 60 days of immunization against rabbits and pasterellosis. 3. Use concentrated preparations and long-acting preparations more, use small needles to reduce stress and skin damage. Raising a good female rabbit produces good 1. A reasonable blood distribution. In the spring and autumn, no more than twice a year, mainly aimed at strong, good maternal, and should strengthen nutrition, blind blood distribution easily lead to premature aging and even death of the female rabbit. 2. Prevention of abortion and stillbirth. Pregnancy rabbits should be careful to take medication, do less inspections, avoid scaring, strengthen nutrition and care. 3. Do a good job of immunity. Inoculate Staphylococcus seedlings 15 days after pregnancy to prevent mastitis. 4. Rational use of compounding to increase litter size. 5. Breeding in the early morning and giving birth during the day to facilitate nursing. (Qi Mu)
