Musk breeding technology

First, the morphological characteristics of moles?
The genus Mole is a small, precious fur beast of the order Rodentiae, Hamster, and Mole, commonly known as the root maggot, and the musk rat. The body is like a big mouse, 35 to 40 cm in length and 23 to 25 cm in length. It is larger than a vole and has a body weight of 0.8 to 1.2 kg. The mole is densely covered with brown, black or chestnut back and brownish gray. The tail is brownish-black in color and slightly flat on its sides. There are scaled skins on top and sparse brown hairs. In mice that had lived independently from their nests, the lateral aspect of the tail was not obvious. Mole head is small, slightly flat, and the neck is short and thick with no obvious boundaries with the trunk. Eyes are small, ears are short and long hairs are hidden, and long hairs are blocked in the ears. Mouth blunt, with beard. The upper and lower jaws each have a pair of long, sharp incisors, light yellow or dark

Yellow, exposed outside the lips. The limbs are short, the forefoot is 4 toes, the claws are sharp, the toes are not flawless, the hind foot is slightly longer than the forefoot, there is a half turn between the toes, and there are bristles. There is a kind of mole that is similar to a mole and should be distinguished. The mole is smaller than the squirrel, and its tail length is only 5 to 6 cm. It is cylindrical and not flat. There are no moles between the hind limbs and the body hair is lighter. ?
Second, the significance of the development of squirrel breeding?
Muskrat is native to North America. Due to its good quality and high economic value, the rat has attracted the attention of European countries. By the twentieth century, dozens of countries in the world have introduced breeding, and they have all achieved success. In 1979, Nahe County, Heilongjiang Province, specialized in raising squirrels, and provided valuable experience for the nation's artificial breeding of mole rats. In recent years, trials have been successfully carried out in Jilin, Liaoning, Zhejiang, Sichuan, Hebei and other provinces, and they have rapidly developed throughout the country.
(a) The mole has a higher economic value?
1. Fur?
The fur used by the Mole in all seasons has its use value, and its fur is characterized by strong water absorption, warmth, and non-wet conditions. Moles live in the water more, so the skin is oily, it is a very precious fur, can be made of high-grade fur clothing, its hair is shiny, black, fuzzy and soft, gray. With a plucking machine, unplugging the hair can be processed into different types of pelts. A fur can be divided into 3 parts: back, belly, side (or both sides). Different parts, different quality, but also have their own best use. ?
2. Can meat be eaten?
The Mole's meat is delicate, nutritious, delicious, with a protein content comparable to that of beef (19.5% to 20.0%) and a low fat content (3.6%), which can be freshly cooked into delicious dishes on the table. ?
3. Mole fragrance?
Male rats can secrete musk musks through the gonads of the reproductive system during the period of 4 to 9 months of reproduction, which has a strong aroma. Muskrat can be used as a raw material for the perfume industry to refine and refine high-grade perfumes. It has been proved that the squirrel scent contains components such as muscarinone and heptacycloalkanone. It also proves that besides having the same effects as natural musk, it can prolong the time of blood coagulation and has an effect on the prevention and treatment of thrombosis and shows a broader effect. Take advantage of the outlook. ??
(B) artificial breeding of moles have a good economic benefit?
The mole skin is a rare animal skin, and for the valuable and high-quality hides, the international market has been the trend of purchase and sales booming in recent years. In China, the Mole has been listed as a key animal of fur by the state. It has been designated by the state as a mink, and the international market has a trade volume of over 10 million, while China’s annual acquisition volume is only a few hundred thousand. Therefore, the prospect of Mole Fur entering the international market is promising. ?
The cost of breeding the moles is very low. The one-year-old breeder only needs to invest 15 to 20 yuan, and the younger rat needs 5 to 10 yuan. A pair of breeding mice can breed 10 to 15 a year and can harvest 10 to 15 furs, each with an average cost of 15 yuan, and only fur can earn about 150 yuan, plus the income of meat and musk aromas. Its economic benefits will be higher. ??
(3) Is it important to protect resources and ecology?
The Mole is a natural wild resource, but according to investigations, in recent years, due to the destruction of the natural ecological environment and the indiscriminate killing of some major producing areas, this resource has plummeted and the prospects are worrying. For example, the wild mole in the Xingkai Lake area was originally High-quality mole rat skin production areas are now almost reaching the point of extinction. Therefore, it is of great ecological significance to protect the mole resources by vigorously developing the artificial breeding of mole rats. ?
Third, the ecological habits of moles?
(a) Environmental requirements?
1. Lax temperature requirements?
Mole's adaptability is very strong, and the temperature and humidity requirements are not very strict. It can survive and breed in the cold northeast and arid northwest regions of China, and it can also settle in humid, warm and even hot and humid regions in the south. ?
2. Like to burrow at the water's edge?
Mole often live in low-lying areas, swamps, lakes, rivers and ponds, where the plants are lush and the environment is quiet. Their caves are mainly distributed along the banks of the river. In the shrubs of shallow water reeds and cattails, some nest on water-like objects. The caves are branched, with many blindfolded branches. There are several granaries, storing feed and several passages leading straight to the place where there is water. ??
(b) the law of activity?
Muskrat loves activities, but due to its relative obeseness, short limbs and weak body, its range of activities is relatively small, relatively fixed, and regionally strong, and the time, number of times, and course of activities are also regular.
The Mole enjoys swimming, water activities, diving ability is strong, can not be exposed for 2 minutes, if you encounter enemy enemies can dive for 5 minutes without breathing, up to 7 minutes. Travel speed can be 20 to 35 meters per minute. Most of the summer is in shallow water areas, and autumn and winter are in deep water areas. Mole fighting, action is hidden, under normal circumstances the different families of mice are difficult to get along with each other, and most are based on blood relationship groups, and in fighting against the enemy, often at the expense of casualties. Mole's vision and smell are quite dull, but the hearing is very sensitive. ?
Fourth, the breeding and growth of mole rats?
(a) breeding?
The reproductive system of the Mole is anatomically similar to other mammals such as rabbits and coypu, except that the male rats of the mole have a pair of special squirrel glands located on both sides of the penis between the abdominal muscles and the pelt. On the inside of the penis, it weighs 1-9 grams. During the mating season, the glands secrete milky yellow oily mucus, which has a strong aroma. In the non-matching season, the shampoo gland shrinks and no secretions are produced. Musk glands are one of the main by-products of the Mole. The appearance of the glands is elliptical, with a diameter of 10 to 15 mm and a longitudinal diameter of 18 to 20 mm. The size of the gland changes with the size and developmental stages of male rats. The whole gland consists of sachets and fragrant glands. The sachet is a thin film covered with capillaries. The capsule is spongy. Many irregular acini are formed in the capsule and there is an oily mucus in the capsule, that is, the original musk. From March to the breeding season, the fragrant glands begin to develop and secrete the musk scent. Its function is mainly to transmit excitement information through scent and lure the estrus of the female rat. ?
1. Sexual maturity?
Muskrads are generally sexually mature at 6 months of age and can be mated.
2. Sexual performance?
Muskrat is a multiple-eating animal that reproduces seasonally and estrusly. Males and females have some differences in sexual performance. The sexual performance of male rats is relatively strong from March to October. After the coldest winter day just passed, the male rat showed a strong sexual desire. The performance was irritability and excitement. The testicles were obviously falling, and the glans were sometimes exposed. The fragrant glands began to secrete the smell of muskrats and shed a strong fragrance to lure the female rats. In November, the sexual desire of the male rats weakened, their sexual performance was not obvious, the glands stopped secretion, and the testes retracted into the abdominal cavity. In general, when a mother's estrus reaches its climax (ie, estrus), the male rats also have the largest amount of scent. The mate's libido performance is relatively late, generally only beginning in mid-April, manifested as tweets, restlessness, excitement, frequent urination, changes in the vulva, and so on. The maternal estrus cycle is generally 15 to 22 days. The maternal estrus cycle is divided into four periods:
(1) During the 13 to 20 days of depression, the mother's mood was stable, and she refused to follow the male rats. The vulva was tightly closed and dry. The skin of the vulva contracted yellowish-white. ?
(2) In the early stage of estrus, 1 to 2 days, they showed excitement and screaming. They paid great attention to the movements of the male rat, but refused to climb over the male rat. During this period, the genitals of the female rats began to relax and appeared wet, resulting in mild swelling and pinky vulva mucosa. ?
(3) The estrus time extends for 2 to 3 days. During this period, the degree of excitement of the female rat increases, the number of calls increases, and the frequency increases. The loss of appetite was noticeable, the genital area was congested, and the vulva at the entrance of the vulva was red and there was a lot of mucus outflow. The estrus mothers like to chase the male rats in the water and quickly make bent and bent back postures when they land, accepting the climbing of the male rats. ?
(4) From 1 to 2 days after estrus, the state of high excitement gradually normalized and the appetite increased. Stop the tweet and refuse the male rat to climb. The enlargement of the vulva subsided, and the opening of the vulva was narrowed to close. The color changed from purple to pale, showing a normal pale red color, and vaginal discharge was also greatly reduced. ?
3. Mating and breeding?
Mole has the following characteristics:
(1) 2 to 3 days after farrowing can be "blooded", 15 days after delivery can be estrus mating again. However, in both cases, the chance of conception is very small. Only in the second estrus cycle can pregnancy be mated. ?
(2) Mating is mostly done in water, and mostly in the early morning or early evening. ?
(3) On the morning of the second day after mating, the vagina can detect the white tubular colloidal plug formed by the secretion of seminal vesicles from male rats. If the plug is excluded, the female can accept the mating again. Otherwise, no mating will be accepted. . ?
(4) Mice that receive mating can breed most of them. The Mole is a multiple litter animal. ?
(5) The gestation period of the mole is very short, only 27 to 28 days, and each fetus can produce 6-9 calves. A female can theoretically breed 20 to 25 animals each year. ?
In fact, the number and frequency of breeding fetuses of the Mole, in addition to their climatic conditions, are closely related to many aspects such as provenance, feeding and management, feeding conditions, and disease prevention. ??
(b) the characteristics of growth and development?
One-day-old squirrels are like small pink meatballs; two-day-olds gradually grow small hairs, and begin to grow incisors; at the age of 10 days, the body's villi are denser, the back is grayish or light brown, the ventral surface is grayish yellow, and the incisors are long. Up to 1 mm; 12-day-old with 6 and 4 black plaques arranged in a zigzag pattern on the chest and back; 13-day-old eyes open, individual starting from 18-day-old; 20-30 days old The coat is basically long, thick and dense, and the incisors can reach 4 to 5 mm. After 100 days, the development of the pups begins to slow down; by 5 to 6 months, it is an adult rat. The pups can crawl slowly in 13 to 15 days; after 18 days, they have the action of biting the grass and scavenging for food; 19 to 22 days to feed; 22 to 26 days to escape; 23 to 29 They began to swim in the water and fight each other; they could live independently on the 30th and generally weaned at 26 to 30 days; they can be bred and breed at 6 months of age. Generally speaking, the best breeding age of the mole is 1 year. Mole life 4 to 5 years, up to 6 years. The breeding habits of domestic rat are 2 to 3 years.
Five, Mole's food?
The moles love to feed on aquatic plants. Their young shoots, tender shoots, green leaves, fruits and roots and tubers are good foods. The young parts and fruits of terrestrial weeds, wild vegetables, and woody plants are also good foods. Cultivated crops such as vegetables, fruits, stems and leaves of food crops, and seeds of grains, beans, etc., are important concentrates and supplementary foods. ? Mole grass-based foods, animal foods eat very little, generally only in the lack of plant feed or breeding season, moles during the disease need to feed, only occasionally eat small animals, such as river clams, snail, Miscellaneous fish, loach and so on. The Mole has a wide range of food sources and generally does not suffer from seasonal shortages. However, foods of different seasons still have different palatability. During the wintering period and the lactating period, due to reduced activities, in the case of stocking, when the moles are dispatched, they often collect a large amount of food at one time, and store them in the “granary” of the tunnel. The storage warehouse is generally very clean and dry, so The stored food is rarely rotted and deteriorated and can be stored for a long time. There are no special "granaries" in the home-reared sheds. Generally, they store food in the corners of small rooms or hallways. Mole body size is small, food intake is not large, the general daily intake is equivalent to 40% to 50% of its body weight, that is, every day to eat plant feed 0.25 to 0.5 kilograms; grain seeds 25 to 50 grams is enough. Relatives eat more in summer and less in winter. ?
In addition to eating fresh feed, the Mole also has the habit of eating soft manure, and eats the newly released manure to further digest and absorb nutrients such as protein, inorganic salts, and vitamins. ?
Sixth, artificial housing care related technology?
(i) Construction of housing?
Large-scale artificial farms use standard housing, and households raise common cages. In any case, Mole's pens must have three parts, namely a nest room, a playground, and a pool. The nest room is divided into two compartments: the inner compartment and the outer compartment. The inner compartment is larger and the outer compartment can be smaller. The inner room is for calving and the outer room is for rest. The specific forms can be varied, roughly divided into two types: flat and three-dimensional. ?
1. Flat-style housing?
The flat ring is three parts at a flat height. ?
The bottom surface and the four walls of the flat-type house should be made of masonry and concrete. According to the size of the farm, it is determined that several or more of them are connected together. The size of each part can be as long as it is relatively reasonable and not very strict. • The stadium should be slightly tilted toward the pool, and a small platform should be built in front of the nest room for food and rest. The top of the stadium is covered with barbed wire or asbestos, but leave it at the mouth. The pool shall be leveled with concrete, to ensure that it has a sufficient depth (0.2 to 0.3 meters). Drain holes are required in the pool to change the water. This lap is suitable for rearing guinea pigs. ?
2. Vertical house?
The nest room and the sports ground are on the upper floor and are connected by a ladder up and down. This type of housing is convenient for winter insulation and summer heatstroke, and it also keeps the resting and breeding environment dry, which is beneficial to reproduction. The breeder should consult with the construction method of the water seal hole, the full closure, and the floor type nest room. ?
3 young rats group housing?
After the pups grow into pups, they should be kept separately. Therefore, special puppies should be established. Rats weighing about 0.5 kilograms can be intensively reared, and their nests, playgrounds and pools are shared. But more than 100 days can not be polyculture, easy bite frame, causing skin injuries or even death.
(b) Introduction?
The first place to build a farm is to buy seeds from outside and expand breeding. After a certain scale, they will be selected. The introduction of the rodent has a link that merits great attention, namely selection and transportation. ?
1. Kind of mouse choice?
(1) The optimal time for seed purchase is March to April and September to October each year. It is neither cold nor hot at this time, it is easy to transport, and growth and development are in the best period. ?
(2) Breeding rats of 5 to 10 months of age are best used as breeding rodents. That is to say, in the autumn, the first spring in the spring should be bred; in the spring, the second and third child in the first year should be selected.
(3) Appearance selection Conjunctiva moist, eyeful, lively, well-balanced, uniform coat, bright color, rich undercoat, flexible hairy rat. Male rats require large individuals and have thick and powerful hind limbs. Female rats require slender bodies and high limbs. ?
(4) Males and females are difficult to distinguish between males and females in appearance. The gender of bred rats can be comprehensively determined from the following aspects:
1 The distance from the anus to the urogenital hole is about 1/3 of that of the male. ?
2 The quilt between the anus and the urogenital hole, the male hair dense, the mother's hair thin. ?
3 Turn the urogenital hole and expose the purple-black round glans as male, if the pink void (vagina) is the mother. ?
4 If both sides of the urogenital hole are touched, if there is a bulge, it is a male mouse (uplift part is epididymis and musk glands), and if not, it is a mother mouse. ?
5 urination characteristics, lift the tail to make intermittent urination, the general male rats to the head, mother rats rearward. ?
6 Be bold on the behavior and the male is rough. ?

(5) It is best to select from different places, or from different farms in the same place, or from different groups of mice in the same farm to prevent degradation caused by close relatives. ?
2. Kind of rat transport?
(1) It is best to use small cages, one for each cage, and two or four cages can be connected together to form a "male-mother-mother-male" four-in-one, which can prevent the aggressive male rats from biting each other. Casualties are also conducive to transport. ?
(2) Feed the feed before departure, and put some green and juicy feed in the cage to allow it to feed freely. For long-distance transportation, prepare ready-to-eat melons, radishes, cabbage, etc. Vehicle transportation should cover wind, block rain and avoid the sun. Train transportation should pay attention to ventilation and ventilation. ?
(3) Observe the mental state at any time in the transportation, carry out water bathing in summer days, and ensure drinking water. In the water bath, place the cage diagonally in a large basin filled with water, and let the mouse immerse in water and breathe with bare head. ??
(c) nutrition and feeding?
For the nutritional needs of mole rats, the current domestic study has only just begun. Previously, farmers have been estimated based on experience. This is unscientific. Due to the lack of research, the views of various parties are not uniform. We only select the most practical test results to introduce to everyone, that is, research on nutrition levels and growth and development. Studies have shown that the level of digestive energy and crude protein requirements can directly affect the size of the yak body size, skin extension and reproductive performance. When the genetic conditions are the same, the protein concentration in the feed becomes a major factor in the growth rate of the pups. Experiments have shown that when the crude protein level in the diet is 18% to 20%, the daily weight gain and the feed utilization rate are the best. If the protein concentration is too high, there will be no good results, but the protein feed will be wasted. In terms of feeding, in addition to the foods that the Mole has eaten before, special mention has been made of some poisonous plants that Mole does not like to eat. They are Yuzhu, Xiaoyuzhu, Violet, Cocklebur, Aconitum, Ranunculus, Pulsatilla, hawthorn, clematis, sided marigolds, turfgrass, shishi, araceae, ramie, tobacco, celandine, hemp, poisonous celery, hoof, buckthorn, solanum, mandala, ephedra Wait.

(four) feeding and management points?
1. How to prepare for breeding management?
The preparation period for breeding is a period of transition from quiescence to breeding, generally from January to March, about 100 days. The main task of this period is to promote the rapid development of reproductive organs to ensure normal sexual function during the breeding period. ?
(1)Supply sufficient vitamin A, vitamin E plus some malt, carrots, etc. At the same time, sufficient water supply provides swimming conditions. ?
(2) Adjust the body condition to reduce the supply of high-fat diets, increase the amount of exercise, enhance physical fitness, and strengthen nutrition for those who are too thin.
Always keep in touch with people for manual operation. ?
(3) Dividing litter and pairing Rats aged 5 to 10 months were selected as breeding mice to avoid matching in the case of close relatives, and to eliminate excessive fat or too thin. Adaptation training is required before pairing by first placing two individuals of similar age, size, and weight in rectangular cages with barbed wire at the middle, so that they can sniff each other and see if they can bite. Hours or 1 to 2 days later, if the scent is the same, they can be put together.
2. Breeding period management?
(1) Breeding method The traditional method is to put the male and female rats (1 male and 1 female) that have been determined to be kept in the same room until the end of the breeding season. The disadvantage of this method is that the male rat cannot be fully utilized during the breeding season. It may also be caused by the mother's mouse for a year-long emptying and a great loss. The better method is to "replace the rodent method." After a pair of male and female mates have been paired for a period of time (approximately 30 days), there is still no indication that the mother has a pregnancy. The male rat should be removed and placed in other estrus rat pens. The male mouse should be tested and observed. Sexual ability before use. If the original mother is estrus again, another male mouse must be paired with it. This method can make full use of the reproductive ability of male rats. It is more meaningful for a large number of mothers and pregnant women who have not seen her for several days after her litter. ?
(2) Feed supply Because the breeding rats (especially the male rats) consume a lot, they must strengthen the nutrition. At this time, fresh and delicious aquatic plants should be fed to supplement animal feed and vitamin A, vitamin E, etc. The feed should be at noon. One-time replenishment is good. ?
(3) Ensuring that the breeding pool of the breeding environment is full and clean and ensures water quality, because the mating is carried out in water. Keep the surroundings quiet and the light dark. If necessary, cover the pen with black cloth. ?
3. Feeding management during pregnancy?
(1) After mating for 10 days, grasp the mother's tail with her left hand and lift it so that her forepaw grasps the cage wall. The right hand is in the shape of an "eight". It gently gropes from the groin to the chest on the abdominal wall of the mother's rat. Peanut-sized, slippery and unobservable embryos. ?
(2) To ensure that the nutritional mole has a lot of litters, the embryonic development is very fast and requires a lot of nutrition. The key to this period is to feed good quality feed, fresh and diverse, and ensure the need of protein, vitamins, and minerals. If you do not pay attention to nutrition, often cause miscarriage, stillbirth or weak.
(3) Prevention of miscarriage, miscarriage and abortion are important tasks in feeding and management. Due to moldy feed, undernutrition, especially vitamin B and vitamin E deficiency, can cause pregnancy interruptions in pregnant mothers, resulting in the absorption of embryos or abortions; accidental injuries and certain infectious diseases can also cause miscarriage. After the mother's pregnancy, she is suddenly depressed, hi lying in the room, and often returning to the genitals, which is often a sign of a miscarriage. In order to prevent abortion, mothers should be provided with fresh, full-price nutrition and constant feed to prevent mechanical damage, keep quiet, and avoid disturbing. For mechanically-induced abortion, only see the fetus without blood, can progesterone intramuscular injection 0.5 ml. If the abdomen suddenly becomes smaller in the abdomen, the underdeveloped fetus in the vagina or the red-brown lumps and contaminated blood are excreted, or the shiny “feces” in the oil are emitted, it indicates that miscarriage has occurred.
(4) Prenatal preparation is mainly to sweep the nests, lay the mats, and reinforce the pens, resulting in a stable litter environment and avoid harassment. If the mother rat is frightened, she will be arrogant. Sometimes she will eat the newly born pups, or she will give up her feed and starve to death. ?
4. Feeding and feeding management?
One to two days before childbirth, the male rat gets up and it sends the grass to the nest to feed the grass in the nest. While the grass is used to block the door to the stadium, it is very busy. This means that the mother rat will be pregnant. • When you hear a mouse "call", you can be considered as having a baby. A female can produce 2 to 3 fetuses a year, with each fetus being 34 to 35 days apart. The maternal rats are born with 6 to 7 adolescents, and the maternal rats have 4 to 7 aces per fetus, with an average of 6 piglets, and the survival rate can reach 99%. After the mother has given birth, she will not produce her nest for a week or so. The male rat is very busy. She keeps feeding the herd, blocks the grass, guards the sports field and the outer room, and protects the mother's body with a door when there is a case. Safety. Sometimes dystocia occurs. When it is discovered that the expected date of birth exceeds, the female's genital area will be red and swollen, blood will be discharged, and it will shrink violently. There will be excretory actions, but the fetus will not appear or be stuck in the birth canal. At this point should be urgent injection of pituitary or pituitrin, intramuscular injection of 0.3 ml. If it is still not produced in 20 minutes, it can be injected again. If no output is produced overnight, artificial midwifery is required. Artificial midwives generally use a low concentration of disinfectant to clean the vulva, then lubricate the vagina with glycerin, and then pull the fetus out with the mother's contraction, and if necessary, take a caesarean section. ?
5. Nursing and gender identification of pups?
The mother of a mole is very strong, and the milking power is also good. Generally, it is not necessary to carry out excessive artificial auxiliary nursing for the pups, so long as the nursing mother is good. • Gloves should be worn for sex identification of pups, and should be performed when the mother has a nest. Occasionally, both hands should be rubbed and checked. After 1 to 3 days of age, the pups had purplish red nipple marks on the ventral surface of the pink, but there was no prominent feeling. On the 4th to the 6th, the nipple slightly protruded from the surface; at the age of 6 days, the abdominal hair was After growing up, the nipples were covered, and only a small dot was seen on the part of the villi. On the 10th to 13th day, the chest villi covered up the dots and the abdomen could still be seen. After 14 days, the chest and abdomen could not be seen. This is female. If the ventral surface is flat after birth, there are no signs of nipples, and occasionally only irregular black spots appear, this is a male. Using the above method to identify female and male, the accuracy rate can reach 97.6%. Of course, after 100 days of age, the discrimination rate can reach 100%. ?
6. Feeding management of pups during growth period?
The pups can leave the room 20 days later and can wean 30 days (at the latest 40 days). Robust, individual and large can be separated first and then divided into small and weak ones. The young rats have snack habits, the number of feeding is generally 3 to 4 times a day, close to maturity after 60 days of age, can be fed according to constant, that is, 350 grams per day, fine material 50 grams. ? Always change the water, diligently clean, diligent food supplements, pay attention to inspections, especially to help young swimmers can not climb up the shore to avoid drowning. ?
7. Winter management?
From October to January of the second year, it is the recovery period of overwintering. During this period, it is mainly to keep warm and increase heat. Keeping the cold is also very simple, as long as you try to make the sheds solid and airtight, keep warm, and lay more hay on the inside of the nest. It will be dry and soft. Change the water supply, clean the pool, prevent freezing cracks. Every day apart from feeding some juicy feeds, some hay can also be fed. In addition, 40 grams of concentrate each day is fed. In addition, the squirrels have the characteristics of food storage, so they do not need to be fed every day when feeding fodder, and it is best to feed once every 10 days or 15 days. In this way, they can also use these forages to block the wind and keep the cold. It is worth noting that the Mole's winter activity is reduced and it is easy to produce diseases. Special attention should be paid. The most prone to affect the intake of incisors, should always check, if too long should be timely cut with pliers. ?
Seven, Mole's fur processing?
The Mole's fur processing is the same as that of the beaver fur process. It can be peeled into strips or stripped into a cylindrical shape. The initial processing process is also divided into three steps: scraping, squeezing, and drying, but the seesaw is The size is somewhat different. ?
Eight, Mole's incense technology?
The incense can be taken on living and dead bodies. ??
(a) Deadly incense?
During skinning, the sachet is carefully peeled away. The sachet is located on both sides of the ventral midline in front of the urogenital hole of the male mouse. When taking the capsule, the end of the opening, which is the urethral opening, is clamped with tweezers or hemostats, and then released. Carefully peel off one hand, like peeling a pig's gallbladder, to prevent it from peeling off, fade the film off, then peel it off, remove it from the root, and remove the incense.
(b) Take incense from living body?
Before taking the incense, Baoding Mole needed to use a wire mesh to make a Baoding cage. The cage was conical, 30 cm long, with an upper opening of 5 cm and a lower opening of 15 cm. The male rat was put on his tail, and he was put into a Baoding cage. When he drilled into the upper opening, he quickly rapped the rat's neck and drew it safely. Another person touched the exact position of the sachet with the thumb and forefinger, and then massaged it gently for a while, then squeezed the mouth of the defecation tube a few times to make the mouth of the deodorant open, and then from the upper part to the lower part of the sachet. Segment massage and squeeze squeeze, the liquid will flow out of the foreskin. Hold the test tube or glass bottle in another hand. After collecting incense on one side, collect the other side. Use appropriate force when collecting incense, so as not to cause pain in the mole and suppress the secretion of incense. ?
