Changmao Rabbit, which currently uses a large number of rabbit hair to fabricate fabrics in the world, has a sharp increase in the demand for rabbit hair. Currently, more than 100 foreign investors have requested supply from China, but the supply of products is in short supply. For this reason, the purchase price has doubled, and now the domestic first-class product purchase price is 90 yuan per kilogram, and the second and third grades are 70 yuan and 63 yuan respectively. As the saying goes: "Family raising three rabbits, simmering in salt and vinegar, and raising ten rabbits, it looks like a small vault." The long-haired rabbit breed is mainly fed with German long-haired rabbits, also known as German Angora rabbits. This breed has strong fertility. Young rabbits grow rapidly, yield is high, and the rabbit hair quality is good. A rabbit grows 1.5 to 2 pounds for a year, which is high. Up to 3 pounds. Its greatest feature is its large back hair density, with an average of 1047 roots per square centimeter. The rabbit hair is of a good variety with wavy bending. The hair fiber is about 20% thicker than the whole eared rabbit and the gun hair content is 5%. About the use of rabbit hair growth additives formulated by the Animal Husbandry and Veterinary Institute of the Jiangsu Academy of Agricultural Sciences, if the diet is supplemented with 1% additives and each adult rabbit feeds 3-4 feeds per day, the rabbit's wool production can be increased by 25%. , long-haired rabbits, also known as Angora rabbits, spread all over the world, like other rabbits, scared scared, good at night activities, hi quiet, dry, clean environment, fear of moisture and heat, cold resistance than anti- Strong heat, long hair rabbits, in addition to the idea of ​​selecting good varieties, but also do a good grasp of feeding management, reproductive technology and disease prevention and other technical measures. Long-haired rabbits should adopt cage culture. The best choice is to choose a rabbit house with a high topography, good drainage, sufficient light, and a clear air, and then hang a wooden cage in a rabbit house to raise 2 rabbits per cage. Raise, is conducive to feeding, disease prevention and reproduction, and to ensure that the rabbit hair is white and flawless. The general specifications of the rabbit cage are 60-70 cm wide, 50-60 cm deep, 40 cm in front of the cage, 34 cm behind, and the bottom plate of the cage. The distance between the mandrel is 14-18 cm in front and 20-25 cm in the rear. The rabbit cage can be stacked to 3-4 layers so as to make full use of space. The distance between the first layer of rabbit cage and the ground is 30-35 cm and rabbit cage is required. Ventilation, dryness and proper lighting, daily cleaning, regular disinfection, male rabbits have a special large rabbit cage, fertile female birth to use a dedicated cage, the baby must have activity cages after the baby, the rabbithouse must be blocked Dead rat hole. Rabbits are mainly herbivorous and have a high yield. They are also suitable for fine materials. The rabbit's caecum is well developed, and the digestibility of crude fiber is second only to cattle and sheep. Adult rabbits need about 1 kg of green fodder and 2 mix feed each day. Green fodder includes wild grass, crop vines and vegetables, bean leaves, sunflower leaves, black locust leaves, red flowers, leaves, and the like. And horse potatoes, carrots, watermelon rinds and so on. As the saying goes: “Rabbit eats 100 kinds of grass, relying on people to find it.†It is also possible to plant high-quality materials such as grasses and bitter grasses on a highly marginal basis. In winter and spring, hay and peanuts and dried potato vines can be dried. The compound feed can be composed of various ancient types, beans and their non-staple foods, such as corn, bran, barley, vine and bean cakes, and peanut cakes. It is generally based on bran or corn, and the protein content of cakes should account for more than 20% (including fishmeal, silkworm cocoons, etc.), but also with 2-3% of bone meal, salt, in order to protect the growth needs of rabbit hair. Daily feeding 3-4 times, timing, quantification, order, especially at night to maintain adequate green feed and drinking water, green feed requires clean, do not entrain sediment, rain, no feeding, erosion, rancid or spray pesticide feed Feed should be kept clean to prevent stiffening overnight, and the proportion of feed and feed should be 40% for bran, 30% for barley, 20% for soybean cake, 6% for corn, 1% for bone and 1% for bone meal, or: 10.2% for soybeans, green beans Powder 28.85%, bran 4.7%, wheat 10%, soybean meal 0.53%, sorghum 1.52%, corn 6%, malt 19%, tuber slag 7%, salt 0.5%, beer slag yeast 1%, pomegranate residue 2.5% , trace elements 0.7%, methionine 0.4%, meat 7.1%. When the pups are born within 3-5 days, they should be given colostrum as early as possible and breast-feeding once or twice a day. The colostrum has a reaction of diarrhea and can help the pups to expel the fetus. In addition, the colostrum is rich in protein and antibodies. The disease resistance of the puppies increases the speed of growth. The pups can eat after 15 days of age. The main feeding is 30 days of age. The pigs can be weaned 40-45 days old, and the young rabbits must speed up their movements. The rabbits have to be fed in separate cages. The rabbits have the feature of “lounging around the nightâ€. The breakfast should be late for breakfast and dinner. “The grass is full at night and the rabbit can grow.†The female rabbit weighs about 6 pounds when it is 6-7 months old. Rabbits aged between 8 and 9 months weighing about 7 pounds can be initially bred. The ratio of female to male rabbits is 1:10. If artificial insemination is performed, a male rabbit can be equipped with 100-200 rabbits a year, and mating should be strictly prohibited. In order to prevent the degradation of the variety, the male and female parents of the university may be male or female. Rabbits should be strong, large, and produce more hair. The male rabbit must be male and the testicles should be well-proportioned. The female rabbit should have more calving and lactation, and the mother should have good results. In order to stimulate ovulation, female rabbits must have mating stimuli to cause ovulation. When long-haired rabbits are sexually weak, the female rabbits may be forced to breed if they refuse to breed. When sexual intercourse, the female rabbit should be placed in a rabbit cage for about ten days, and pregnancy tests can be performed. The method is to gently pinch the abdomen of the rabbit by hand and touch it from front to back. If there is pregnancy, it can be flexible. If you are able to slide and have a bean size that does not have the experience of keeping a tilapia, you may make another compound 5-7 days after the breeding. If the female rabbit refuses to mate, it is usually pregnant. Female rabbits are pregnant for 30-31 days. Pregnant female rabbits should not feed malt, hemp leaves, ramie leaves, etc. Do not casually catch rabbits during pregnancy. When you need to grasp, you should grasp the neck with one hand. Keep your hips cool, comfortably and quietly, and stop the hair removal and plucking. In the summer you must supply cool drinking water or dilute salt water. In the 25th day of pregnancy, the rabbit cages and maternity boxes should be disinfected to the familiar environment of the female rabbits. , In order to order grass, pull the hair to make the nest mother rabbits 3 days before birth, to reduce the amount of feed material to feed more green materials such as summer more often to feed the car before the grass, wolfberry bowl, Xiaoqing and water spinach bitter vegetables, etc., postpartum to be timely Give the damsel some salt water. There are 5-6 litters and more than 8-9 litters. It is advisable that each female is breast-feeding 6-7 eggs. The excess rabbits can be transferred with the litter size to find nanny rabbits. The nanny rabbits should Select the birth time within 3 days of the difference, the nanny rabbit milk squeezed a few drops on the foster puppies to avoid the death of the pups, you can also raise some long-haired rabbits while maintaining local rabbits, For nanny rabbits. Let the puppies eat the nanny rabbit's milk after eating 2, 3 days of breast milk. This method enables the West German long-haired rabbit female rabbit to mate with the male rabbit 12 hours later, and its fertility can produce 3 or 4 births a year. Long-haired rabbits can generally be hair-fed after 3 months of birth. State purchases are priced according to length, and rabbit hair quality requirements are “long, loose, white, and cleanâ€. Rabbits should be combed after milking and 40 days after shearing of adult rabbits. The rabbits should be combed every 10 days. In order to put the knot together, comb the hair with a sparse tooth steel and aluminum comb first neck back shoulder, back, back, straight hair direction combing from the top down, young rabbits easily cut rabbit hair, one year can be cut 4-5 times, Adult rabbits can be plucking hair, pulling out once a month, generally use shearing, first combing and cut the back, then cut the abdomen, cut the knife against the direction of the hair and no longer cut, but be careful not to put the teat and Testicles cut off winter hair removal to leave the abdominal hair, to prevent cold, and let the rabbit drink some clean water. In the rainy season, put some ash in the rabbit cage to reduce the humidity in the rabbit house. When cleaning the rabbit houses, the rabbit cages should be disinfected with 5% solution of Lysol, or rabbit cages should be washed with 2-4% caustic soda solution, the equipment should be washed on the ground and sports grounds, and some garlic, onion or press must be added to the feed. Contains 150 mg (3) of chloroquine per kilogram of concentrate to prevent coccidiosis in rabbits. Weaned rabbits continue to feed this feed for a month and a half. In the event of an outbreak of coccidiosis, chlorpheniramine can be doubled and required to be treated for 1-2 weeks. Before midsummer, the rabbit must cut the hair once. Open air rabbit house to take a pergola, the indoor temperature is too high, some cool water can be poured to cool, the cage can not cut off drinking water, the winter season to do a good rabbithouse insulation, to prevent the intrusion of cold wind, do not feed frozen ice feed, not too much hair . When adopting rabbit hair, methods of combing, dialing, and cutting can be determined according to specific conditions. According to the rabbit's long, white, loose, and net, grading, respectively, storage, classification sale, according to hair up to 1.7 inches for the special grade, more than 1.4 inches to 1 level, 1.1 inches above the second level, there are The knotting pollution is classified as minor hair. Store to prevent absorption of moisture, extrusion, insects, keep clean and loose, do not use plastic bags, so as not to affect the quality of the rabbit after the hair should be fed more bean cake, bean dregs, bran, so that rabbits grow new hair in time . There are the following two methods for the Cui Mao and hair removal of the long-haired rabbit: First, every rabbit after the hair-cutting, use two tablespoons of shochu, add a little ginger and mix well, rub the entire body of the rabbit (be careful not to apply into rabbit eyes), Cui Mao is performed on long-haired rabbits. The second is to use a vitamin B12 injection, plus 1 ml of fat fat Ling, after the shearing of the subcutaneous muscle injection. Add 1 g of sulfur per rabbit per day in the feed to increase 20% of the gross production. The second method is Cui Mao, the new hair is dense and homogeneous, and the quality is very good. For example, a multi-leaf feed with a sweet feed, such as carrots, a sulfurous feed, such as a radish leaf, or a vegetable high-fat feed, and conditions permitting Under the circumstances, adding a small amount of honey, loquat powder, vegetable oil, etc. to the rabbit feed can increase the mouth opening and promote the rabbits to produce high quality hair. The long-haired rabbits have their own hair removal, as long as they are given oral cyclophosphamide 60-100 mg once per rabbit weighing two pounds. After 7 days, the rabbit hair will fall off automatically. The hair removal takes only 1-2 minutes. The effect is very good. After depilation, the skin is smooth and the amount of hair removal increases by about 20%. The second time, it can grow quickly and evenly. It can be increased by 0.5-0.7cm. The cyclophosphamide tablets used are manufactured by the Shanghai No. 11 Pharmaceutical Factory. All are for sale, priced at 0.7 yuan per gram, each rabbit hair removal once only about 0.14 yuan. In addition, to raise long-haired rabbits should always observe the rabbit's spirit, appetite, feces have no change, pay attention to whether the rabbit's thin, body temperature, breathing is normal, such as the discovery of disease, timely isolation and vet treatment. The most common disease in long-haired rabbits is rabbit plague, which is a severe skin disease in long-haired rabbits and is highly contagious because of the parasitic effects of rabbit lice and rabbit lice on the skin surface of rabbits. The affected area had hair loss, redness and swelling, and the epidermis had white ecdysis. The rabbit suffered from itching and it affected the growth and development of the long-haired rabbit. Now introduce two kinds of rabbit lice treatment prescription. 1. Rub the affected area with 5% purple gold tablets and 10% trichlorfon. After two minutes of application, wipe the residual liquid with a dry cloth and sprinkle with powder. This is safe and has a high cure rate. Second, to the Chinese medicine shop to buy back a small amount of one hundred in the rice wine dip, and then take its leachate, with a clean brush pen liquid applied to the affected area, continuous medication for three days, this side can also treat rabbits. The excrement should be promptly removed. Concentrate fermentation is beneficial to sterilization and increase fertilizer efficiency. It can be used as a high-efficiency organic fertilizer, and its nitrogen content is higher than that of other livestock manure. Rex Rabbit Breeding and Feeding Rex Rabbits are also called Rex Rabbits and Velvet Rabbits. Because its fur is similar to the otters, it was named Rex Rabbit. It is a rare skin rabbit species. First, Breeding: Rex rabbits can usually mate with 5 to 6 months of age. In breeding, we must choose the same color of the rabbit to mating, at the same time require that there can be no relatives within three generations to avoid inbreeding. Rex rabbits usually breed four times a year. Matching time The first child in late March, the second child in mid-June, the third child in mid-September, and the fourth child in the middle of the 12th is appropriate. The number of days of pregnancy is related to the number of embryos, usually 30-31 days. The period of the rabbits is 2-3 days, and they all have a phenomenon of grassland title. Practice has proved that the earliest niche grass to make nests, the better the motherhood, laying hair within 2-4 hours after birth can also be another characteristic of the rabbit labor. If a litter box with a short-cut straw is placed 1-2 days before delivery, the female rabbit that does not jump into the nest in the table box will generally not give birth in the table box. In the winter, this kind of female rabbit must pay attention to observation, otherwise the puppies will be frozen and die. Once the puppies are found outside the box, they must be returned to the box. For females whose genital swelling is more than 31 days after pregnancy, 5 units of synthetic oxytocin can be induced by intramuscular injection. In most cases, the female rabbit automatically jumps into the table box to give birth and to suckle the rabbit. Second, feeding and management: dietary standards and compound feed formulations due to the large variety of rabbits feed, the rabbit dietary standards and the proportion of compound feed are also different, under normal circumstances, rabbits daily supply of green feed 800-1000 grams, Compound feed 100-250 grams. Formulated feeds are as follows: Adult rabbit: corn 10%, bean cake 1%, barley 20%, bone meal 1.5%, wheat husk 40%, salt 0.5%, rice bran 10%, additives and auxin 1%, digestive energy 2911 Card/kg, digestible crude protein 126 g/kg. Young rabbits: 7% corn, 20% soybean cake, 17% barley, 3% fishmeal, 40% wheat, 0.5% salt, 1% bone meal, 1.5% auxin and additives, digestive energy 2939 kcal/kg, digestible Crude protein 148 g/kg. In terms of feeding, green feed is the main source in summer and autumn, and hay and succulent feed are the main products in winter and early spring. Don't come too suddenly when changing the feed. The newly-changed feed should gradually increase. If the change is too fast, it may cause food loss or food refusal. The green feed is fed three times a day. It is required to feed early in the morning, feed less at noon, and feed at night. The amount of night meal should account for more than 50% of the daily amount. Green materials should pay attention to species diversity, do not feed a single species for a long period of time, in order to increase palatability, the supply of winter green materials is difficult, and high quality hay can be added. Nursing mother rabbits can not be interrupted, it is important to take care of. Meat rabbit rabbits are rich in nutrients and delicious meat. They are important meat products and are also traditional export products of China. They are very popular in the international market. Rabbits are easy to breed, grow fast, have a wide source of feed, are well managed, have low feeding costs, and have good economic returns. With the improvement of people’s living standards, there will be great development prospects. First, the meat rabbit feed (a) feed type 1, green feed. Commonly used green feed include weeds, pastures, barley, vegetables, and aquatic feed. Green feed is rich in nutrients, vitamins, minerals, high content, good palatability, rabbits love to eat, high digestibility. 2, hay. Its nutrient composition depends on the type of grass, timing of harvest, drying conditions, storage quality, etc., so the nutritional value of hay is relatively high. 3, roughage. Mainly by-products of crops, such as oyster shells, corn cobs and so on. This type of feed has low nutritional content and poor palatability and can only be fed in moderation. 4, energy feed. There are barley, wheat, corn, rice and so on. 5, protein feed. Plant protein feeds include soybeans, broad beans, peas, various kinds of cakes, and animal protein feeds including fish meal, meat and bone meal, silkworm meal and blood meal. In addition, there are mineral feeds and vitamin feeds. (2) Dietary Coordination: Scientific diets should be based on actual conditions in different regions. Some breeding units provide adult rabbits with 0.8-1.2 kg of green grass, 0.1-0.125 kg of fine material, 0.2-0.35 kg of hay in winter, 0.2-0.3 kg of block material, and 0.1-0.15 kg of fine material. Bean cake 25%, wheat bran 20%, cornmeal 47%, fishmeal 5%, shell powder 2%, salt 1%, multi-vitamin 0.05%. Feeding additives, such as nutritive additives, growth promoting and health supplements, are also needed during feeding. Second, feeding and management of rabbits feeding methods are: cage care, hole care, fence raising, stocking and so on. Cage culture is more suitable for management and breeding. The disadvantage is that there are no sports grounds. The hole is raised: the venue is large and can be reared in groups. Stocking: Suitable for raising rabbits and rabbits. Rabbits are herbivores and should be fed mainly with green fodder, supplemented by concentrates, and the diet should be composed of a variety of feeds. The summer should be dominated by green feed, and winter should be based on hay and block feeds to prevent sudden changes in feed. Fill the non-supply clean drinking water, the best drink warm water in winter, rabbits afraid of heat afraid of wet, we must often clean the rabbithouse, keep the rabbit nest clean and dry, to be able to sun to the sun and appropriate exercise to enhance the rabbit's resistance to disease. (A) Breeding and management of male rabbits: Male male rabbits require strong physique, but they are fat or too thin, and their sexual functions are vigorous. Give enough protein, minerals and vitamins to feed when feeding. The male rabbits should be raised in cages, caged with rabbits, prevented from biting each other, and kept away from the female rabbits. Rabbit cages should be sterilized frequently. (B) Breeding and management of breeding female rabbits: The empty female rabbits should be fed with fine green fodder and appropriate amount of concentrated fodder, without over-slimming, maintaining 7-8 percent of cicadas, with proper light and heat and exercise, and promoting estrus. breeding. For pregnant female rabbits to provide high-quality feed, green feed can be freely eaten rice, supplement mixed concentrate should be controlled at 100-120 grams. Must have sufficient minerals and vitamins, and pay attention to nursing and prevent miscarriage. The female rabbit is pregnant for 30 days. Before the child is born, the disinfected litter box is placed in a cage. The bottom of the box is covered with a layer of clean and soft straw. The delivery room should be on duty and kept quiet. After giving birth, the female rabbit should provide enough clean drinking water. The female rabbit should be weaned for about 40 days from the time of childbirth to the weaning of the pups. This period should be fed easily digestible, nutrient-rich feed, with sufficient protein and minerals. With vitamins, ensure plenty of water. Every day, clean the cages, wash the utensils, disinfect regularly, and keep the cage clean and dry. (3) Feeding and management of puppies: During the sleeping period, puppies must fully eat the mother's milk. When necessary, artificial breastfeeding should be carried out. Milk and cod liver oil, eggs, and salt are used to feed into mixed milk to prevent rat damage. Eye-opening puppies should feed feed in a timely manner, give a small amount of milk, milk, rice soup, tender grass, soft leaves, etc. at 16-18 days of age, after 20 days of age can be fed cereal, bean dregs, minerals, etc., to 30 days of age After that, it gradually became feed-based, supplemented by breast milk, and weaned at 40 days of age and transferred to young rabbits. (IV) Feeding and management of young rabbits and bred rabbits: Weaned to 3 months old young rabbits. At this time, for feeds that are easy to digest, small in size, and high in nutrient levels, the food intake will increase with the age. The young rabbits should be divided into small groups according to the size of their age, physical strength, and keep the cage clean, warm and dry. At the age of 60 days, activities outside the cage began to be released, and sunlight was more commonly seen to enhance physical fitness. Raised rabbits aged over 3 months were the fastest growing stage. To ensure the needs of various nutrients, high quality hay, green feed and minerals were fed. In 4 months, concentrate feed should eat enough to feed, and more than 5 months of age should control the feeding of concentrated feed to prevent over-fertilization. After 3 months of age, sexually mature young rabbits have already started estrus. They must be divided between males and females to prevent early mating. (E) Rabbit fattening: fattening after the skeleton grows, should be fed more concentrates such as barley, wheat husk, oats, peas, potatoes, hawthorn, broken rice, corn, bean dregs, bean cakes, etc., and add bone meal, salt, The way to feed is to feed more and less meals. Male rabbits cast off before fattening. During fattening, they should be kept in a damp, dark heap and reduce activity to facilitate fat storage. III. Propagation methods Meat rabbits are suitable for mating age. The female rabbit is 5-6 months old and weighs 3-3.5 kilograms. The male rabbit is 7-8 months old and weighs 3.5-4 kilograms. The skin is both rabbit and rabbit. The female rabbit is 6-7 months old. , Weight 3.5-4 kg, male rabbit 7-8 months of age, weight 4-4.5 kg. The useful life of rabbits is 3-4 years for male rabbits and 2-3 years for female rabbits. The estrous female rabbits can be placed in male rabbit cages after early feeding. If they are close to male rabbits, they can be successfully bred. After the mother is assigned, she should be put back in the cage and rest quietly. In order to increase her pregnancy rate, it can be supplemented once before the night's feeding on the same day. Conditional insemination can be carried out. In order to improve reproduction rate and breeding quality, it is better to breed. Plan to choose the best opportunity for breeding.
