Provide a suitable environment
1. To build a cold-proof and warm-keeping rabbit house in winter, the optimum temperature for maintaining the growth of the rabbit is 15-25°C. When building a rabbit house, it is necessary to choose shelter from the sun, heat and dry, quiet environment, convenient water and electricity, and no pollution. When designing and constructing, consider sunny, ventilation, heat preservation, and good heat insulation; make the incident angle of sunlight not less than 25-30 degrees, and the lighting area can reach 15% of the ground area. The use of hollow bricks or reinforced concrete as wall material can increase the coefficient of thermal resistance of the wall, and the addition of plaster to the wall can make 35% to 40% of the heat dissipation not easily emitted through the walls. The roof should be covered with a thick seal, with a 45-degree high-span slope. If conditions allow, a glass wool or polystyrene foam board with good insulation properties can be used as a ceiling. The interior of the house is 20-30 centimeters taller than the house. It must be smooth, firm, compact, easy to clean and sterilized, and heat-preserved.
2, control the house temperature in winter, low temperatures, in order to increase the temperature, first increase the breeding density, relying on the rabbit body heat to increase temperature. The second is to minimize ventilation to a minimum in order to preserve the heat generated by the rabbit body. The third is to cover the transparent plastic film before and after the rabbithouse to make full use of the sun's light, increase the amount of lighting as much as possible, reduce heat dissipation, and achieve artificial temperature increase. Conditional installation of heating equipment, such as heating, electric heaters, stoves, fire pits and so on.
3, timely removal of harmful gases First, timely removal of excreta, dirt, lime moisture, keep the house clean and dry bath, regular disinfection. The second is to ventilate and ventilate in time, install ventilation devices, and strengthen automatic ventilation. You can also open doors and windows at 11 noon to 2 p.m. daily, use the natural wind to change the air, and grasp the smell at any time.
The summarization of staged scientific management is: Do a good job of "three levels" and ensure that the safety of the rabbit is "three stages."
1. Make sure that you are born and close enough to ensure that your puppies are fully fed and have a good night's sleep and that they should grow and develop normally. 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 materials to ensure eye-opening, breast-feeding healthy growth. 100% of the nutrition of most puppies within 14 days of age 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. From 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 for the female rabbit and improve the feed quality. From 20 to 45 days of age, mothers are separated and fed individually to provide nutrition, digestible, fresh and hygienic, good palatability, and fine processing of high-quality feed supplemented with minerals, vitamins, and anticoccidial drugs. 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 the weaning off after 40 days of age began to reduce the number of maternal exposure, and reduce the female rabbit's nutritional level, reduce the amount of milk until 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. Reasonable grouping will be based on sex, weight, and strength. 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 had 4-5 cages (about 0.5 square meters in area) and the fattening rabbits had 2-3 cages per cage.
5. Reasonably arrange for sports young rabbits to strengthen their sports, adopt cluster stocking, and release them centrally at noon every day, and return 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. Do not use male rabbits, can be cast and fattened in about 70 days.
Rex rabbit winter feeding management technology
Rex rabbits grow fast, have a short cycle, are good for meat and skin use, and have high economic value. In recent years, it has been favored by domestic and foreign markets. Raising rabbits is a good project for farmers to get rich. Although in recent years, the production of domestic rabbits has developed relatively rapidly, in terms of producing high-quality rabbit skins, the requirements for feeding conditions are relatively high. Especially in the winter, if improper feeding and management, it will not only cause an increase in feed consumption, increase the mortality of the disease and increase the expenditure, but also seriously affect the quality of fur, but also restricts the rapid development of production. The technical highlights of winter rabbit rearing and management are described below for reference.
