First, feeding and management (A) do a good job of cold insulation Rex rabbits are animals that are resistant to heat and cold, but their ability to withstand cold is limited. Temperatures below 5°C will affect the growth of Rex rabbits, especially if the newly born puppies are particularly afraid of freezing. Below 10°C, they will face puppies. Survival poses a threat. Therefore, it is very important to keep the rabbits afloat during the winter to do a good job of keeping warm and cold. 1, although the winter temperature is very low, in addition to newborn puppies, the rabbithouse temperature is not demanding, but the temperature must be relatively stable and can not be hot and cold. In winter, the optimum temperature for the growth of rabbits should be 15 to 25°C. Overcooling and overheating have a great influence on their physiological functions, generally not lower than 10°C and higher than 29°C. 2, increase the breeding density, rely on the rabbit body itself to increase the temperature; at the same time the rabbit breeding density can not be too large, to increase the breeding density. Young rabbits should not be reared in single cages, and puppies must be moved to rooms with higher temperatures to increase their survival rate. 3, indoor rabbits should be closed doors and windows, aquaculture often say "not afraid of a wind, afraid of thief wind first-line" should prevent thieves wind invasion; outdoor rabbits, it is necessary to do insulation measures to prevent invasion of the cold wind. Try to minimize the amount of ventilation in order to save the heat generated by the rabbit itself. 4. Full and reasonable illumination is a necessary condition for the normal growth and development of Rex rabbits. Generally, artificial lighting and natural lighting are commonly used. The transparent plastic film can be covered before and after the rabbit house to make full use of the sunlight, maximize the amount of indoor lighting, and artificially increase the temperature. Rex rabbits can obtain good production performance under light conditions of 12 to 16 hours per day. Conditions can also be installed in the heating equipment, such as heating, electric heaters, stoves and so on. (B) Strengthen Feeding Management 1, supplement feed supply. Due to the low temperature in winter, rabbits consume more calories. Therefore, the daily feeding amount of large and small rabbits should be 20% to 30% higher than usual, and the proportion of high-energy feeds should be appropriately increased. In addition, due to lack of green feed in winter, prone to vitamin deficiency, should try to feed some leaves, carrots, barley malt and tuber-like feed, etc., to supplement the deficiency of vitamins. 2, powder to add a small amount of bean dregs or bran, wet with warm water and then feed, and do less feed Tim Tim, to prevent the remaining material after eating ice. 3. Use wet mix when using coarse powder. Coarse powder should be mixed and stirred uniformly. Before feeding, press 1:1 with warm water to mix wetness. Generally, when grasping the wet material in hand, the water should not be dribbled with the water between the fingers. The mixture is used now and mixed one time. In order to maintain the freshness and palatability of the feed. 4, a reasonable mix of feed. Rex rabbits are herbivores. Since feeding artificial grass exclusively to feed green grass can not meet the nutritional needs of rex rabbits, in addition to feeding some fresh and fresh feeds on a regular basis, they must be equipped with full-rate pellet feeds in a certain proportion. The benefits of the full-price pellet feed are: not freezing in winter, mildew in summer, relish in rabbits, and comprehensive nutrition. When mixed feeding, green feed should be used in a variety of combinations, fresh and clean, and supplemented with sufficient supplements. When eating freely, the content of various nutrients in the mixed feed should be controlled at 10.46 to 11.72 kJ per kilogram of feed, 18% at the early stage of crude protein, 14% at the late stage, 3% to 5% at the crude fat, and crude fiber. 12% to 15%, calcium 0.5% to 0.7%, phosphorus 0.3% to 0.6%. Scale feeding should use full price with granular feed. When free-range, it is advisable to adopt coarse green, and then make up fine material. 5, the amount of daily feeding should be reasonable. The number of feedings per day is generally controlled at 5 to 6 times/day for puppies, 4 to 5 times/day for young rabbits, and 3 to 4 times/day for fattening rabbits and adult rabbits. Dietary volume: It depends on the production conditions, body weight, good or bad condition, and digestive abilities. Regular feeding: 4 times a day, that is, 6:00 to 7:00 in the morning, 11:00 to 12:00 in the afternoon, 4:00 to 5:00 in the evening, and 9:00 to 10:00 in the evening. The daily feed amount is 25% in the morning, 20% in the noon, 20% in the evening, and 35% at night. 80% of each meal is appropriate, and the amount of each feed is not the degree of food left in the tank. After feeding, add green feed as a supplement. To forage at night. When changing feeds, the amount of new feeds should be gradually increased. Do not suddenly change all of them. Prevent and control emergency response and diarrhea caused by refueling. 6. The baby nest box should be changed frequently to keep it dry and warm. 7. Both small and large rabbits should lay a small amount of hay in cages to prevent freezing at night. (3) Doing a good job in rabbit house hygiene In winter, special attention should be paid to improving the environmental hygiene of rabbit houses and regularly disinfecting the rabbit houses. Disinfection requires the disinfection of more than two kinds of disinfectants to prevent the occurrence of drug resistance; the rabbit house should be cleaned frequently, remove the excrement and dirt every day, use damp lime to prevent moisture, keep the house clean and dry, and prevent the accumulation of excrement and reduce it. The production of irritating gases such as ammonia and hydrogen sulfide prevents the occurrence of respiratory diseases such as rhinitis and pneumonia. In addition, the disinfection should be serious and the rabbit house should be kept dry. In order to keep warm, the rabbit house in winter has been airtightly closed, but the ventilation is poor, and harmful gases such as ammonia gas, hydrogen sulfide, and sulfur dioxide have increased. It is easy to induce retinal diseases such as conjunctivitis and rhinitis. Therefore, ventilation equipment is installed to enhance automatic ventilation. In good weather, it is also possible to open windows and doors from 11 noon to 2 p.m. daily, using natural air for ventilation, and the size of ammonia odor can be grasped at any time. (D) do a good job overwintering pests In order to make the rabbit safe winter, enhance the body's quality, apply ivermectin or abamectin, insect repellent net and other drugs before wintering (late autumn), take injections or spices to take all the rabbits once and for all Control of insects to prevent the invasion and harm of parasitic diseases. (five) Do a good job of winter breeding While doing a good job of cold insulation, it is very beneficial to arrange winter winter breeding. Its advantages are high survival rate and slaughter rate. The puppies grow fast, have a large body size, a strong physique, and good fur quality. As long as people work hard to prevent cold and keep warm, breeding breeding in the winter still can get better economic benefits, especially the high survival rate of young and young rabbits, and fewer diseases. In actual production, as long as the insulation of the litter box is done, the mat is dried, soft, strong in heat retention, and good in hygroscopicity. If the temperature is kept above 10°C, a good winter complication can be obtained. In winter, the temperature is reduced, the pathogenic microorganisms are inactive, the infectious pathogenic microorganisms are few, the rabbit disease is small, and the survival rate of the young rabbits is high. It is entirely possible to create a constant temperature environment for the rabbits and to carry out winter winter breeding. Although the female estrus is not obvious, but after all, can estrus, able to ovulate normally, therefore, we should seize the opportunity to breed female rabbits, breeding time should be selected at noon on sunny days, no wind, warm day. It is necessary to grasp the good agricultural practices in breeding: Pink is early, Black and Purple is late, and Dahong is at that time. In order to increase the conception rate, the mating method can be repeated or double mating. In addition, 12 days after mating, the female rabbits should timely touch the tires. The method of touching the tires is to hold the female rabbit's ears and collars in the left hand and fix the female rabbits on the flat ground or the desktop so that the rabbit heads towards the touching tires. The person's chest, the right hand was inverted 八 shape, and placed in the abdomen of the female rabbit, gently from the back to explore, the embryo was spherical and elastic, dung ball was hard spherical, and inelastic. For empty pregnant female rabbits who are not pregnant, they must make up for it in time. In addition, the winter rabbit breeding period should be long, generally do not engage in blood, to breed 1 to 2 children is appropriate. (VI) Phased scientific management To sum up, it is to do a good job of "three levels" and ensure that the safety of the rabbit is "three stages." 1, grasp the birth of customs. Ensure that the pups are fully fed and sleep well during the sleep period and that normal growth and development should be achieved. In addition to ensuring the nutritional status of pregnant rabbits during pregnancy and lactation, the first is to record delivery time and prepare for delivery. The second is to allow the rabbits to eat colostrum in a timely manner after birth, adopt compulsory feeding, artificial breast-feeding, foster care and other measures, implement mother-to-child care, breast-feeding on time, artificial breast-feeding and other measures, and thirdly, effectively protect the rabbits from heat and freezing. Anti-pressure, anti-suspended milk, rodent-proof, ensure quiet and comfortable mother's life. 2, do a good job feeding material off. Ensure healthy eye opening and lactation. 100% of the nutrition of most puppies within 14 days is obtained from breast milk. When he opened his eyes and had a certain amount of activity and body temperature adjustment ability, he began to recognise the fodder. From then on, he embarked on a drastic change that took the lead from breast milk, followed by feed intake, and then to independent living. At this time, there are multiple stages of stress reaction. At 15 to 20 days of age, the mother is fed in the same cage and feeds together to increase the amount of feed and trough of the female rabbit and improve feed quality. From 20 to 45 days of age, the mother's bedding is separated, and the rabbits are individually supplied with nutritious, easily digestible, fresh and hygienic, good palatability, and processed with fine quality feed, and supplemented with minerals, vitamins, and anticoccidial drugs to reduce inflammation and sterilization. Stomach, anthelmintic drugs. Gradually reduce the number of breast-feeding, increase the amount of feed, eat less meals, provide sufficient warm water, and gradually adapt the puppies to the external environment of independent living. And we must constantly check the farrowing box, replace the bedding in time, and weed out the weak puppies. 3, grasping weaning off. After 40 days of age, the number of maternal exposures was reduced, and the female rabbits were reduced in nutrient levels and lactation levels were reduced until milk was stopped. After 45 days of age, the physique was strong and well-fed puppies were fully weaned. Infirm pups stay for around one week in the female rabbit. When weaning, mothers should be left to stay in order to prevent sudden changes in the environment. 4, rational grouping. According to the sex, weight, strength, group feeding. Determine the stocking density according to the size of the cage. General adult male and female rabbits are kept in separate cages (shepherding). The young rabbits have 4 to 5 cages (about 0.5 square meters in area) and 2 to 3 fattening rabbits per cage. 5, reasonable arrangements for sports. The young rabbits strengthened their sports and adopted cluster stocking. They were released every day when they were warm at noon and returned to the cage after 4 pm. Fatty rabbits restrict exercise so as to reduce the consumption of nutrients in the body and accumulate nutrients in the body. The fattening rabbits are kept in small cages and placed in a warm, quiet, dark place for best fattening. For female rabbits that breed poorly, the breeding male rabbits with low value should be eliminated in time and the cost of breeding should be reduced.

How to manage rabbits in winter
The temperature in winter is low, the sunshine hours are short, and there is a large temperature difference between day and night. At the same time, the lack of green feed has brought certain difficulties to the feeding of rabbits. At this time, the feeding and management of rabbits is particularly important. If improper feeding and management, it will cause a waste of feed consumption, increased mortality and affect the quality of fur and increased the cost of breeding, but also laid the constraints for the rapid development of rabbit breeding a hidden danger. Therefore, Rex Rabbit's feeding and management in the winter is very important, and its key is to do a good job of cold insulation and winter winter breeding. Rabbits in winter feeding and management should do the following.
