First, to strengthen seed selection and selection is the basis for the selection of improved survival rates in puppies. Select females with good motherhood, strong lactating power, many litters, and healthy, disease-free, sexually active, but not fat or too thin. For use; for those who have fewer litter size, low conception rate, poor motherhood, poor lactation performance and female rabbits suffering from birth or death must be eliminated. Do not sour when you are mated: close relatives do not deserve, immature unworthy, young and old unworthy. Breeding commercial rabbits and adopting double mating to obtain robust offspring. Second, the scientific rearing of female rabbits, especially to strengthen the feeding and management during the later period of pregnancy, is to increase the survival rate of young female rabbits. After pregnancy, as the fetus grows and develops and its own body Metabolism strengthens, it needs to consume a lot of nutrients, especially pregnancy. In the later period, the fetus grows fast, and more than 90% of the body weight is increased at this stage. For this reason, it is necessary to provide enough nutrients for pregnant females, especially proteins, inorganic salts, and vitamins. The specific approach: the better the use of the method of the first Qing Houjing, the pre-pregnancy to green feed mainly every day feeding 800 - 1000 grams. In addition, about 100 grams of supplemental concentrate should be fed, and the amount of concentrate fed should be appropriately increased by the end of pregnancy. For female rabbits with poor lyrical condition, the daily feeding method was adopted from the beginning of pregnancy. Every day, except for 600-800 grams of green feed, the mixed concentrate was gradually added from 100 grams to 150-200 grams per day. Quick recovery of body lice, to meet the female rabbit itself and fetal growth needs. As a result of strengthening the nutrition of the female rabbit (especially in the later stage of pregnancy), the female rabbit has a strong constitution, a good fetus development, a major new birth, a good constitution, and a strong life force. At the same time, the female rabbit has a well-developed mammary gland, and the lactating force is strong after delivery, and the young rabbit grows. Fast, high survival rate. Careful care and careful rearing are the key to raising the survival rate of the puppies. 1. Prior to the birth of the pups, the rabbits should be born 3-5 days before they are born, ready to be sterilized, paved with a soft, dry maternal box, and have a special person to stay up late On duty, in order to prevent the female rabbits from dying on the bottom of the cage or leaking to the ground. After the birth, do a good job of cold insulation work, especially to prevent cross-wind and thief wind attacks. For frozen rabbits produced outside the box, they can be immersed in warm water at 40°C (head exposed) to revive them or use a 25-watt bulb for heating. According to the characteristics of neonatal young rabbits with poor body temperature regulation, the mini-environment temperature of the crate is often maintained at 20-25°C. At the same time, the doors and windows are closed, and cages are closed to prevent rats, dogs and cats from invading and harming the pups. 2, as soon as possible so that the puppies eat milk, eat full milk 1 to 3 days postpartum colostrum is rich in nutrients, is the best source of nutrition for puppies. Enzymes and antibodies in colostrum can enhance the resistance of the cubs, promote growth and reduce death. Therefore, after the baby is born, let him eat milk and eat enough milk as early as possible. For female rabbits who are not feeding on time, artificially forced breast-feeding is used. That is, the female rabbit is fixed on the back and the nipples are exposed. Then the pups are placed on the nipples and allowed to feed. For this reason, pups who died or gave birth to more calves than the number of pups were used for foster or artificial nursing. When fostering, females who have fewer litters, more milk, and at the same time or successively no more than 3 days of delivery, are placed on the puppies before delivery to carry the mother's urine or milk in order to prevent the mother from biting or refusing to feed. Artificial feeding, replace with cow's milk or rushed milk powder, milk temperature 37--38°C is appropriate, 1--2 times a day. 3. After the baby has been raised in separate cages, it will be moved to the Other cage together with the breeding box and separated from the female rabbit. In the morning, the female rabbit will be sucked into the cage of the rabbit for 10-15 minutes and then put back into the original cage. . Adopting the mother-in-a-chicken cage-feeding method can timely observe the condition of the bunnies, which is convenient for the bunnies to create a warm, clean and quiet environment, prevent the occurrence of hanging milk, and can prevent the female rabbits from stepping and dying of the bunnies, especially After puppies have eaten, it is beneficial for puppies to feed on their own to prevent the females from competing for food and infecting the disease due to eating food contaminated by the feces of female rabbits, thereby reducing the spread of many diseases (especially coccidiosis). Improve the survival rate of puppies. 4. Feeding after 16 days of reasonable feeding can feed feeds rich in nutrients, containing less crude fiber, and easy to digest. According to the characteristics of small stomach volume, weak digestion and fast growth, it should be small and multi-meal. , Even feeding, gradually increase, the first Qing later refined, first make up for young grass such as grass, ryegrass, etc., 18 days after the start of feeding full-priced compound feed. 5, timely weaning according to feeding level, breeding plan and development status determine the weaning time of pups. High-quality and well-developed can be weaned at the age of 30 days. When weaning, the whole-nest-pig rabbit has uniform growth and development, and the body is strong. The method of weaning is used once. The body strength of the whole litter is different, and the growth and development are uneven. , we can make the first weaning with strong constitution, while the infirm continue to breastfeed. At the time of weaning, feed, environment, and management are to be as stable as possible to prevent the death of the pups when unfavorable stress occurs. Fourth, disease prevention and treatment of bunnies susceptible to digestive tract and parasitic diseases, especially the largest harm to coccidiosis. Therefore, cages, floors, and utensils should be regularly washed and disinfected, rabbits should be cleaned daily, and grass be replaced in a timely manner to keep the rabbit house dry and clean. At the same time, add in the feed to help digestion and absorption, anti-inflammatory, bactericidal and prevention of coccidiosis drugs, such as yeast tablets, charcoal powder, garlic, ball grams of net (or chlorobenzene) and so on. In normal times, early disease and early disease prevention can be done to ensure the healthy growth of young rabbits, reduce the occurrence of diseases, and greatly increase the survival rate.
