Bamboo rats (Rhizomyidae; bamboo rats). The scientific name is bamboo rats. They are also known as bamboo rats, mango raccoons, bamboo raccoons, bamboo root rats, winter-haired rats, etc. They belong to the order Mammalia, rodents, and bamboo rats. Family Bamboo Rat genus. It has a large body, rich meat, delicious taste, rich nutrition, thick and soft fur, and has high economic value. According to measurements, it contains 57.78% crude protein, 20.54% crude fat, 17.36% crude ash, 0.84% ??crude fiber, and 0.05% cholesterol. It is also rich in phosphorus, iron, calcium, vitamin E, amino acids, and steroids, among which lysine The content of leucine and methionine is even higher than that of chickens, ducks, geese, pigs, cattle, sheep, fish, shrimps and crabs. It is a top-quality game product with high nutritional value, low fat and low cholesterol.

The general name of the rodent family Bamboozoidae. It got its name because it mainly eats bamboo. Most are small and medium-sized species, generally between 16 and 23 centimeters in length, but some species, such as the bamboo rat, can reach 45 centimeters in length; their heads are round, their eyes are small, and their ears are hidden in the skin; their tails and limbs are short; their toes are The claws are strong and pointed; the body is covered with long hair, but the tail is hairless or short and sparse; the skull is thick and solid, the zygomatic arch is expanded, the bone ridge is high, and the muscles are well developed; the upper incisors are particularly thick, with 16 teeth in the chest. Inhabits tropical and subtropical forests, shrubs and bamboo forests in eastern Africa and southern Asia. There are 6 species in 3 genera in the world: 2 species of the genus African Bamboo Rat, which are endemic to East Africa; 3 species of the genus Bamboo Rat, and 1 species of the genus Bamboo Rat, which are endemic to Asia and found in southern China. Inhabits bamboo forests, horse bamboo rats

Tiger pine forests and grass on sunny slopes in mountains, and lives under campsites. The tunnel is shallow, only 20 to 30 centimeters above the ground. The tunnel entrance is piled with soil, and soil is often used to seal the entrance. The nest in the cave is often covered with bamboo branches, leaves and dead grass. It likes to eat the underground stems and bamboo shoots of bamboo, and also eats other plants. Giant pandas occasionally hunt for prey. Young rats can be seen throughout the year, and they breed 2 to 3 times throughout the year, with each litter giving birth to 1 to 5 offspring, with the majority being 3. The fur of bamboo rats is long, thick and of good quality. The meat is tender and edible. The fat is called bamboo rat oil and can be used as a topical medicine. The teeth of bamboo rats are also used by patients with kidney stones. The teeth can be ground into powder and mixed with white wine orally. Bamboo rat meat is sweet and mild in nature and flavor. ① "Compendium": "Sweet, flat, non-toxic." ② "Yilin Compendium": "Sweet, salty, flat." Functions: Replenishing qi, nourishing yin, and detoxifying. Treat tuberculosis and quench thirst. ① "Compendium": "Tonify the middle and replenish qi, and detoxify." ② "Yilin Compendium": "Nourishes yin and removes heat, kills malnutrition, treats tuberculosis, and relieves thirst." ③ "Materia Medica Qiuyuan": "Benefits Lung and stomach qi, resolving phlegm and detoxifying. "

Rodentia, Rhizomatidae, Rhizomys and Cannomys. The specific biological information is as follows:

Chinese Bamboo Rat

(Chinese Bamboo Rat, Rhizomys sinensis): mainly distributed in the central and southern parts of China. It is also distributed in areas such as northern Myanmar and Vietnam. Specifically, they include Guangdong, Guangxi, Yunnan, Fujian, Hunan, Guizhou, Jiangxi, Zhejiang, Anhui, Hubei, western Sichuan, southern Gansu, southern Shaanxi, northern Hubei, etc.

Silver Star Bamboo Rat

(Hoary Bamboo Rat, R. pruinosus): Mainly found in the southeastern region of my country, India, the Malay Peninsula and other places. Such as Yunnan, Guangxi, Guizhou, Hunan, Guangdong, Fujian and other places. It lives underground and feeds on reed roots, Imperata cogongrass roots, bamboo roots, bamboo joints, bamboo leaves and bamboo shoots. It reproduces in four seasons, with peak reproduction in spring and autumn. The gestation period is 45 days, with 1-5 babies per fetus, and the lactation period is 1 and a half months.

Large Bamboo Rat

(Large Bamboo Rat, R. sumatrensis): Mainly found in Xishuangbanna, Yunnan, the Malay Peninsula, Sumatra and other regions in my country. Large and obese, it is the largest bamboo rat. They go out in the morning and evening; they feed on bamboo roots, bamboo shoots, and other plants. Breeding and mating occur from February to April and August to October, with a gestation period of 45-50 days; 3-8 animals per litter. The distribution area is narrow, the number is small, and the species is rare.

Lesser Bamboo Rat, Cannomys badius: This is the smallest bamboo rat, mainly found in western Yunnan, Nepal, northern Bangladesh, Thailand, Laos, Cambodia, and Vietnam Waiting places. They are distributed in the tropical rainforest and bamboo bushes at an altitude of about 600 meters along the China-Myanmar border. They mostly survive by digging holes in banana fields and cassava fields. The gestation period is 40 days, with 1-5 babies per litter. The distribution area is narrow, the number is small, and it is a rare species.

Feeding methods

Bamboo rat (Rhizomys sinensis), also known as bamboo rat, belongs to the Rhizotidae family. Bamboo rats are mammals distributed in South Asia and East Africa. There are 1 genus and 3 species in my country. They mainly inhabit bamboo forests or miscanthus bushes on the slopes south of the Qinling Mountains, and live in caves. Feeds on the underground stems, roots, twigs and stems of bamboo. Bamboo Rat

The meat of Bamboo Rat is delicate and delicious. It contains 57.78% crude protein, 20.54% crude fat, 17.36% ash, 0.84% ??fiber, and 3.84% moisture. It is also rich in phosphorus, calcium, VE and amino acids. A variety of delicious and fragrant dishes can be made using ordinary cooking methods. "Compendium of Materia Medica": "Bamboo rat meat is sweet, flat, and non-toxic. It can replenish vital energy and detoxify."

At present, bamboo rat meat has become a delicacy, from the family dining table to high-end banquets, adding luster to the food culture. Bamboo rat skin has abundant plush, smooth color and good board quality. It is the raw material for making fur. Bamboo rat whiskers are high-grade raw materials for making brushes.

Raising techniques

Bamboo rats prefer a quiet, clean, dry environment with appropriate light and fresh air, and are more active at night. Its activity pattern can be divided into activity cycle and rest cycle. It likes warmth, its living temperature is -8-35℃, and its optimum temperature is 8-28℃. It likes to hide in corners with weak light. If it is placed in direct sunlight, it will run endlessly and appear restless. When a person blows on it, it immediately reveals its sharp and thick incisors, and at the same time makes a "whoosh--" sound in demonstration. Under artificial breeding conditions, sexual maturity begins at 4-5 months of age and weighs more than 1 kg. Breeding occurs after 6 months of age. Generally, more than 10 animals are bred per year. The weight of young rats reaches 0.5kg after 3 months of feeding, and can reach more than 1kg at 5 months, with the largest being 2-5kg.

1. Pens

Empty houses, cellars, and air-raid shelters can be used for breeding, or 1.2 There are openings on the wall, one for the inner room and the other for the breeding area. 5 pairs/square meter can be kept in groups, and can also be kept in cages. 1.1 Young rats refer to bamboo rats within 3 months of age after weaning. Feed fresh, easily digestible, and nutritious feed. Such as carrots, sweet potatoes, bamboo shoots. Juicy feeds such as melon rinds, as well as refined materials such as corn, wheat bran, and dry steamed buns. At the same time, fish meal, bone meal, salt, vitamins, and growth hormone are added to the diet to improve feed digestibility and promote the growth and development of young mice. Food types must remain relatively stable, and if there are changes, there should be a transition period. Young rats need to eat 14-17g per day, and feed them twice a day, less in the morning and more in the afternoon. The young rats are raised in separate pools according to their weight and physical strength, with 4-5 rats per cage. The weak ones should be raised alone to promote physical recovery of the young rats. 1.2 Adult mice Adult mice have strong disease resistance, fast growth and development, and weigh 1.2-1.5kg. Feeding should be done regularly and quantitatively, once in the morning and once in the evening. Each animal should be fed 150-200g of straw and 15-20g of concentrate per day. The basic diet does not need to be changed all year round. If it is changed, there should be a transition period. Adult rats' teeth grow quickly, so a bamboo pole or hardwood bar needs to be placed in the cage for them to grind their teeth. Check the bamboo rat's feces every day to see if it has a smooth surface and is granular, like medicinal capsules. Pay attention to whether its coat color is bright and whether its activities are active. If there is an accident, it should be dealt with in time. 1.3 Breed rats Male rats are required to be well developed and weigh more than 1.3kg. The back is straight and strong, with prominent testicles, strong sexual desire, resistance to rough feeding, and no fighting. The mating action is fast and the semen quality is good. The quantity and quality of semen of male breeding rats are related to nutrition, but they cannot be fed too much. Green roughage includes bamboo leaves, bamboo stalks, bamboo shoots, corn stalks, reed stalks, sugar cane, carrots, etc. The compound diet is: 55% corn meal, 20% bran, 15% peanut bran, 3% bone meal, and 7% fish meal. The breeding mice are bred 1-2 times a day. In spring and autumn, when the temperature is suitable, male rats have strong sexual desire and good semen quality. Each estrus lasts for 1-3 days and breeds at night. The breeding ratio of males and females is 1:2-3, with 1:1 being better. Breeding female rats Breeding female rats are required to have a high litter rate, strong mothering ability, strong feeding ability, and a body weight of more than 1.2kg. Due to the growth and development of young rats, adult mother rats also need to raise their young, so the dietary formula for young rats and adult mother rats is as follows; ① 55% corn, 20% bran, 15% peanut bran, 3% bone meal, and 7% fish meal. In addition, add 0.5% salt and auxin according to the total amount. ② Bamboo flour 20%, flour 35%, corn flour 10%, bean cake flour 13%, wheat bran 17%, fish meal 2%, bone meal 2%, salt 0.2%, sugar 0.8%. In addition, every kilogram of feed is supplemented with 1 mg of folic acid, 20 mg of niacin, 75 mg of zinc oxide, 400 mg of D-L methionine, 0.5 mg of potassium iodide, 60 mg of manganese sulfate, VA1500IU, VD31500IU, VB12 20 mg, VB2 6 mg, and VE30 mg. Mix the above feed, add water and knead it into a steamed bun shape or granular shape, then dry it in the sun or oven and feed it to bamboo rats. The "Yueyuejin" full-price feed for bamboo rats is produced by professional technicians from Fuxing Farm and professional bamboo rat farmers. After years of breeding, tracking growth and comparing materials, they selected a veterinary drug formula that has a preventive effect on bamboo rats and is suitable for bamboo rat breeding. Prevent and treat diseases, and promote the rapid growth of bamboo rats. According to the trace elements required by bamboo rats, the bamboo rat "Yueyuejin" full-price feed is formulated. After comparing the feeding of tens of thousands of bamboo rats, the feed formula is used to make bamboo rats Fast growth, less illness, more litters, no litter consumption, labor saving and cost savings of 40%. It takes 8 months to breed commercial rats by ordinary methods to reach the size of 3 pounds. After using Yueyuejin, it can grow to 3 pounds in 4-5 months, hence the name "Yueyuejin"

1.4 Breeding The gestation period of female rats is 60 days. The feed fed during this period must be clean, fresh, diverse and relatively stable. After pregnancy, female rats should be raised alone, and the house should always be kept clean and provided with dry, soft bedding. The delivery time is 2-4 hours, and the delivery can be completed in 1-2 hours at the earliest. 6-7 days before delivery, the nipples of the female rat are exposed, the activity is reduced, and the movement is slow. Before giving birth, the rat makes a "gu--gu--" sound from time to time. During delivery, the baby rat is born together with the afterbirth and placenta. The mother rat eats the afterbirth and placenta while giving birth, and finally bites off the umbilical cord and cleans the amniotic fluid from the offspring.

At this time, you can hear the cry of the rat "ji-ji--". Twelve hours after the mother rat gives birth, she starts suckling her offspring. During delivery, avoid watching and touching with hands and keep the environment quiet to prevent the mother rat from eating or abandoning her cubs. During the lactation period, the mother rat's nest cannot be visited, cleaned, or fed into the nest room. The mother rat can clean the nest room by itself. During the lactation period, compound feed should be fed and the amount should be appropriately increased. At the same time, milk or soy milk should be given every day to increase the lactation volume of the female rats. Mother rats produce more than 100g of milk per day, which is enough to meet the needs of their offspring. The temperature of the house should be maintained at 8-27°C. In summer, when the temperature exceeds 30°C and it is extremely hot, use a fan to blow air and pour water into the pool to cool down. In winter, the house temperature cannot be lower than 5℃, and it is best to keep it around 15℃. Especially when the seasons change, it is necessary to prevent the wind from invading the nest. The pups eat with the mother for 20-30 days after birth. At this time, they are fed fresh and easy-to-digest bamboo branches, grass stems, and full-price pellet feed. At the same time, the female rats were supplemented with minerals and various vitamins. After weaning at 40-50 days of age, the pigs are divided into litters, divided into 2-3 batches, and divided into 1 batch every 3-5 days. The survival rate of the offspring is over 98%.

2. Disease prevention and control

The breeding environment should be regularly disinfected with Baidu and Xinjier. The feed should be fresh and diverse, and no watery or moldy food should be fed. 2.1 Gastroenteritis is mainly caused by feed deterioration, mold or feed mutation. Symptoms: The sick mice have a confused gait, and their feces are yellow-green with blood or white mucilage. Prevention and treatment: Feed fresh feed and take 0.5g of oxytetracycline orally, twice a day. 2.2 Colds are caused by sudden changes in climate and cold. Symptoms: Rapid breathing, dry nose, tears, and clear nasal discharge. Prevention and treatment: ①Intramuscular injection of metamizole 0.2-0.5m1, once a day. ② Inject compound aminopyrine intramuscularly, 1ml each time, 2 times a day. 2.3 Stomatitis is caused by bites, gnawing, or food from cage nets or sharp objects. Symptoms: Reluctance to eat, salivation, flushed and inflamed mucous membranes. In severe cases, the spirit is listless and the body temperature rises. Prevention and treatment: ① Rinse the mouth with 0.1% potassium permanganate water or add it to the drinking water and let the sick mice drink it and take 2 anti-inflammatory tablets orally. You can also use iodine glycerin to rub the mouth. ② For severe cases, 200,000 units of penicillin or streptomycin can be injected intramuscularly, twice a day, with a course of 3 days as a course of treatment. 2.4. Severe trauma or abscess. Abscesses in bamboo rats are mostly caused by injuries caused by fights that are not treated in time or are not treated properly. , commonly seen in bamboo rats, there are yellowish-white suppurative lumps on the head, abdomen, limbs and tail root, which are hard on the outside and soft on the inside when touched. Treatment method: cut the abscess, drain the pus, rinse and disinfect the wound, grind chloramphenicol tablets into powder and mix with peanut oil and rub it, and at the same time, intramuscularly inject penicillin to reduce inflammation and prevent re-infection of the wound; 2.5 Trauma is the most common occurrence in raising bamboo rats. The most common disease. They often bite each other due to competing for food, being frightened, fighting for dens, or being hooked by iron cages during transportation. Improper capture methods cause human injuries. Treatment method: When trauma is discovered, apply medicine such as blue sky iodine, pot bottom ash, ten thousand flower oil, etc. in time. Human trauma hemostatic medicine can be used. When the wound is large, deep and bleeding a lot, Yunnan Baiyao should be applied to stop bleeding and reduce inflammation. The wound cannot be wrapped with gauze, nor can it be applied with ointment or tape, otherwise the bamboo rat will tear off the dressing; 2.6. Colibacillosis, which mostly occurs in spring and summer. The sick rat has a large abdomen and feels turbulent when touched. Female rats are often mistaken for She was thought to be pregnant. An autopsy showed a large amount of jelly-like (transparent gelatinous) leaching in her abdomen. Treatment method: Treat with neomycin and cephalosporin. Rats are injected with 0.5 ml each time, and the number of young rats is reduced by half; 2.7. Heatstroke. If bamboo rats are transported in summer and the temperature reaches above 32 degrees, the ventilation is not smooth in the carriage, or they are exposed to the sun. After 20-30 minutes, coupled with the lack of juicy feed, the water in the body cannot be replenished, and heat stroke will occur. First aid method: Move the sick rat to a cool place, bury its body with wet sand, and expose only the head. After 10-15 minutes, the bamboo rat will wake up. If you cannot find wet sand, you can soak the bamboo rat in cold water and expose its head to prevent it from drinking a lot of water. Otherwise, even if the heat stroke is relieved, the rat will be difficult to feed. In addition, you can also apply cooling oil on the nostrils of bamboo rats. 2.8. Postpartum prolapse of the uterus. When some female rats give birth to their first child, due to excessive force, it is easier to cause the uterus to prolapse. If not discovered in time, the uterus will turn black and emit an unpleasant smell, and eventually the female rat will bite it off. , thus the female mouse loses its ability to reproduce. First aid method: If within two or three days after giving birth, you hear the pups screaming (no milk to eat), you should check the condition of the mother. If it is determined to be post-uterine ejaculation, there are two treatment methods. The first method is to stir-fry soybeans and put them into the pig gallbladder to allow the fried soybeans to absorb the juice of the pig gallbladder. After half an hour, take them out to dry slightly, then grind them into powder and mix them into the food. After two to three days, the uterus will The second method is to apply cooling oil on the cervix of the cervix three to four times a day after uterine ejaculation. The female rat will lick it continuously after application and will slowly recover after a few days. It is worth noting that the above method is suitable for about three days after delivery. If it is discovered more than four days after delivery, the possibility of cure is much lower, and it can basically be declared that it has become a hermaphrodite.

Prospects of breeding

my country has developed rapidly since the successful artificial domestication of bamboo rats in the early 1990s. A new type of breeding industry with high economic benefits.

1． Edible

Bamboo rat has clean eating habits, fine and lean meat, and extremely delicious taste. It is a top-quality game food. It is a kind of nutritious bamboo rat

It is low-fat and low-cholesterol meat. food category. According to measurements, it contains 57.78% crude protein, 2.54% crude fat, 17.36% crude ash, 0.84% ??crude fiber, and 0.05% cholesterol. It is also rich in phosphorus, iron, calcium, vitamin E, amino acids, and steroids. Among them, the content of lysine, leucine and methionine is higher than that of chickens, ducks, geese, pigs, cattle, sheep, fish, shrimps and crabs.

2． Medicinal uses

Modern medicine has proven that bamboo rat meat can promote the growth of human white blood cells and hair, enhance liver function and prevent vascular sclerosis. It has good effects on anti-aging and delaying puberty. It is a natural beauty and body-building product. According to traditional Chinese medicine, the gallbladder, liver, heart, brain, testicles, and kidneys of bamboo rats can be used as medicine. Gallbladder can improve eyesight, refresh the mind and strengthen the brain, and can cure eye diseases and deafness; kidneys can cure scabies and beriberi; liver, heart, and brain can cure palpitation, palpitation, insomnia and other diseases; stir-fry testicles and add a little borneol, dilute with water and swallow Taking it can cure high fever, vomiting and rheumatism; soaking bones in wine can cure rheumatism and rheumatoid diseases. my country's medical industry has always regarded bamboo rat hair as a good raw material for medicinal purposes. Because the main component of bamboo rat hair is hard protein, after hydrolysis, it can be made into important pharmaceuticals such as hydrolyzed protein, cystine and cysteine. Folk medicine is usually used to treat malnutrition and pox leprosy in children. Biochemical drugs such as glycylic acid, thymosin, and cephalin can be extracted from bamboo rat viscera and other scraps. The thread-like white tendons in the tail of the bamboo rat can be used as surgical sutures.

3. Raw materials for fur making

Bamboo rat fur is fine and soft, with an oily luster, thick undervelvet, and moderately thick skin. It is easy to tan, and its fur base is gray and easy to dye. It is the best raw material for making fur clothes. The handling and processing of bamboo rat fur is a relatively complex and highly technical task. The general process is slaughtering → peeling → oil scraping → skin washing → lasting and drying → storage.

Market Prospects

1. There is a strong domestic market

In China, bamboo rats have entered large and medium-sized cities, towns and consumer markets in southern and western regions of my country, and the demand is increasing at a rate of 3% every year. The sales of commercial bamboo rats in large and medium-sized coastal cities such as Shenzhen, Zhuhai, Hong Kong, Guangzhou, Hainan, and Shanghai have been promising, and prices have always shown a strong trend, with sales prices of 100 to 160 yuan per kilogram. A 1kg barbecue bamboo rat sells for more than 300 yuan. Especially around the Spring Festival, sales of bamboo rats are booming, prices rise, and supply is in short supply. According to incomplete statistics, Sichuan, Yunnan, Guizhou, Hunan, Jiangxi, Guangxi, Guangdong, Hainan, Hong Kong, Fujian, Shanghai and other places consume more than 6 million bamboo rats every year. At present, the national bamboo rat production is far from enough. To meet the needs of rapid market growth. In the past two years, my country's bamboo rat breeding industry has begun to gradually heat up, and it has the potential to start a prairie fire. Many bamboo rat

farmers have introduced and breed bamboo rats, which requires a large number of bamboo rat sources.

2． Popular in the international market

Bamboo rats and their products have always been popular in the international market. Nearly 500,000 bamboo rats are exported to Southeast Asian countries every year. Alaska in the United States needs to import 300 tons of bamboo rat meat from my country every year. A pair of leather shoes made of bamboo rat skin sells for 2,000 to 2,500 yuan in the international market, and a fur bamboo rat coat sells for 4,000 to 5,000 yuan, and is very popular. Bamboo rat whiskers cost 40,000 yuan per kilogram, and high-end brushes made from bamboo whiskers are my country's traditional export commodities and have always been best-selling in the Japanese market.

Edit this paragraph Breeding Benefits

Bamboo rat breeding has the characteristics of wide adaptability, food saving, strong fecundity, fast growth, easy maintenance and management, and huge profits. Not only can rural areas be vigorously developed, but it is also suitable for urban residents’ family farming and factory-scale farming. 1. The staple food is straw. Bamboo rats feed mainly on crop straws and plant roots, such as corn stalks, sorghum stalks, soybean stalks, sugarcane roots, reeds, miscanthus, etc. Do not compete with people, livestock, or poultry for food. They don't compete with cattle and sheep for food. Cows and sheep eat the young branches and leaves of plants, while bamboo rats only eat the old roots of plants. In order to ensure the nutrients required for the growth and development of bamboo rats, some concentrated feed needs to be fed. 2. No sunlight or water required. Bamboo rats like to live in a dark, cool, dry, clean environment with a temperature of -8 to 35°C. They also have the characteristic of absorbing water from feed rather than drinking water directly. Therefore, it can be used to build dens for breeding on hillsides and caves in remote rural areas, or it can be used to build dens indoors or in basements in cities and towns for factory-scale three-dimensional breeding. It is also more suitable for farming in arid and water-deficient mountainous areas rich in bamboo forests, corn, and sorghum. 3． Easy to maintain and manage. Bamboo rats are simple to feed and manage. They are only fed once a day or once every three days. Bamboo rats have less urine and dry feces with no odor. They can be cleaned once in summer and once every 3 to 4 days in winter. The workload of raising a pair of bamboo rats is 1/10 of raising a pig, and one labor force can raise 200 pairs of breeding rats. 4． Strong fecundity. One female bamboo rat can breed 20 to 30 offspring every year, and under good feeding conditions, it can reproduce 120 to 160 offspring annually, which is much higher than the reproduction multiple of pigs, cattle, and sheep. Its production level is unmatched by other livestock species. . 5. The benefits are considerable. The weight of young mice can reach more than 1 kilogram after being raised for 3 months.

The current market purchase price of commercial bamboo rats is 5 to 60 yuan per kilogram. Generally, the annual income from raising a pair of bamboo rats is more than 2,000 yuan. A farmer converts a half-acre pig house into a rat pond and raises 6 to 10 pairs of bamboo rats, which can help him escape poverty in one year. Laid-off workers and urban residents use their vacant houses to raise 4 to 6 pairs of bamboo rats in three-dimensional cages or in enclosed ponds, and their income is also considerable. It can be seen that bamboo rat breeding is a new breeding industry with high development value, large market demand, high yield, high efficiency, low consumption, food saving and low risk, and is worthy of development.

Edit this section of the breeding cycle

The first year: introduction--growth--maturity--estrus breeding--farrowing and nurturing. 1. During this period, there will be those who eat their cubs, and there will also be female rats that abandon their cubs. 2. There will also be males and females that are not suitable for breeding due to temperament problems. Those are usually more aggressive and will not change despite repeated admonitions. 3. Male rats with poor sexual performance. It can also be included in the elimination list. The second year: Entering the peak production period - secondary selection: 1. Eliminate those that eat young, abandon young, or produce few young; 2. Those with poor physical fitness are also eliminated; 3. Those with poor reproductive ability are also among them. In the third, fourth, and fifth years: After selection, the excellent adult breeding rats begin to have better economic benefits. However, during this period, the reserve of reserve breeding rats must be considered, otherwise the breeding farm will have " “No cooking” problem. Sixth year: The sexual performance of the breeding rats begins to decline. Use reserve breeding rats to slowly eliminate these rats as commercial rats to ensure the number of high-yielding breeding rats. From the above six-year cycle analysis, the following conclusions are drawn for your reference: 1. The bamboo rat industry cannot see benefits immediately as soon as you invest. To put it simply, doing this industry requires a long-term vision and courage. . 2. For the first introduction, we recommend more than twenty pairs or seven groups (two males and three females). Because only in this way can there be a basis for secondary selection; of course, secondary introduction can also be carried out by going to other fields in the future. When introducing species, first of all, you can consider introducing them to a breeding farm with "two certificates" (i.e., "Wild Animal Taming License" and "Wild Animal Management and Utilization License"); secondly, you can also go to a farm that you are familiar with and trustworthy. Introduced from farms with many years of domestication experience. In this way, firstly, the quality of the source can be ensured, and secondly, corresponding technical support can be obtained. 3. Once on the track of normal development, corresponding reserve breeding rats should be reserved every year to fill the production capacity gap left after the breeding rats are sold as commercial rats.
