6 benefits of raising rex rabbits
It costs 20-22 yuan to raise a qualified commodity rex rabbit of about 3kg. Calculated by per kilogram 10~ 12 yuan, the sales income is 30~36 yuan, and the net profit after deducting the cost can be 8 ~ 16 yuan.
Small prescription for rex rabbit to gain weight
The market prospect of rex rabbits is broad, and how to make rex rabbits gain weight is an important link to improve economic benefits. My experience is that when raising rex rabbits, many rabbits are raised at the same time, so that they mate almost at the same time, or every few days. When they give birth to rabbits, properly dispose of the young rabbits of several rabbits, leaving only 2-3 rabbits to feed the mother rabbits. When the young rabbits grow to 10, they start to feed the young rabbits twice a day, rex rabbits 1 time, and rabbits help to feed 1 time. In this way, until the rabbits are 25 days old, they are fed with supplementary feed, such as bean products, special feed for young rabbits, carrots, fresh grass and so on. After such feeding, the young rex rabbit can grow to 0.5 kg after 1 month, and the heaviest rex rabbit can reach 0.75 kg, which is 0.25-0.35 kg heavier than the rex rabbit raised by conventional feeding methods. Such rex rabbits have strong physique, strong disease resistance, easy feeding and high survival rate.
Eight Skills of Rex Rabbit Breeding
Rex rabbit breeding has gradually become a climate. According to practice, the author summarized eight skills of rex rabbit breeding and development:
Advocate moderate management: the breeder introduces more than 20 rabbits at a time (one male and three females as a group), forming the annual production scale of 1000 commercial rabbits, and seeking benefits by scale. Do not have this condition, can be suspended.
Pay attention to the breeding of improved varieties: strictly select improved varieties according to the characteristics of short, flat, thin and dense fur of rex rabbits. Don't have too many kinds of colors, mainly white and "eight points black", and adhere to the principle of feeding by stages. When the weight is more than two kilograms, we should pay attention to the selection of fur quality indicators, keep the fur plump and smooth for seed use, and eliminate unqualified inferior species in time.
Regularly change consanguinity: after two or three years of breeding, rabbits with different consanguinity (mainly male rabbits) will be introduced from other places, and pedigree management will be strengthened to prevent species degradation caused by excessive inbreeding.
Improve the survival rate of reproduction: Rex rabbits benefit from reproduction. It is excellent for a basic female rabbit to reproduce and survive more than 20 young rabbits in a production year, and it is good for more than 15 rabbits. If the conditions are good, the breeding times can be appropriately increased to improve the utilization efficiency of female rabbits.
Strengthen feed nutrition: Rex rabbits are fur animals, and the protein level in the diet should be maintained at 15% ~ 17%, and additives such as methionine, lysine and cystine should be properly added to improve their fur quality. It is best to popularize granular materials, which can not only close the mouth, but also ensure the nutritional integrity.
Do a good job in epidemic prevention and disease removal: infectious rhinitis, scabies and foot dermatitis are the three stubborn diseases that plague rex rabbits. It is necessary to adhere to the principle of routine epidemic prevention and alternate medication, and strictly control the spread of diseases. Traffic rules will definitely eliminate sick rabbits with no therapeutic value.
Adhere to age-appropriate skinning: The best skinning period is 5-6 months later, when the weight of rex rabbits reaches 2.5 kg, which is not affected by seasons, but it is suitable for skinning aged rabbits in winter. It is necessary to accurately master the operation methods such as slaughtering, unwinding, pickling and drying, and strive to improve the qualified rate of skin grafts.
Pay attention to market trends: Rex rabbit skin and its products are mainly exported at present, and the international market will inevitably fluctuate, so farmers should be psychologically prepared. Generally speaking, the peak season of rex rabbit fur products is spring and summer. At this time, manufacturers are in urgent need of hides, and the price will be higher. And winter is the peak season for product sales. At this time, the grain stocks purchased by manufacturers have also decreased, and the prices will be lower. Breeders should firmly grasp the pulse of the market and get the highest selling price.
How to improve the reproductive rate of rex rabbits
In order to improve the reproductive rate of rex rabbits, measures such as repeated breeding, double breeding, frequent breeding, artificial estrus and luster enhancement can be generally taken.
Repeated mating: In general, most denominator rabbits can get pregnant only by mating once. But in order to ensure pregnancy and prevent false pregnancy, repeated mating can be used, that is, mating with the same male rabbit again 20-30 minutes after the first mating. According to experiments, the conception rate of this method can reach more than 90%, and the litter size can be increased by 2-3 litters compared with one-time breeding.
Double mating: a female rabbit and two male rabbits mate continuously, with an interval of no more than 20-30 minutes. This method can avoid male rabbit infertility and obviously improve the conception rate and litter size. But two-line breeding is only suitable for commodity production, not for rabbit production, in case of pedigree confusion.
In rex rabbit breeding, the female rabbit should be put back into the original cage in time after the first male rabbit is mated, and then mated with the second male rabbit with the same coat color after the smell of the male rabbit disappears. Otherwise, there will be a fight because the female rabbit has the smell of other male rabbits. Not only can it not reproduce smoothly, but it may also bite the mother rabbit.
Frequent reproduction: Frequent reproduction is also called "matching blood". Generally, young rabbits in rabbit farms are weaned in 40-45 days, and then the mother rabbits reproduce, so only 3-4 rabbits can be bred every year, and the reproduction speed is very slow. Frequent breeding means that female rabbits breed within 1-3 days after delivery, so that they can breastfeed and get pregnant at the same time, and the lactation period is shortened to about 25 days, so they can breed 6-8 young rabbits every year, and each female rabbit can breed 40-60 live rabbits every year. Frequent propagation must meet the following conditions:
1. The female rabbit should be healthy. 2. Feed nutrition should be comprehensive. 3. Early weaning of young rabbits. Through frequent breeding, young rabbits are generally weaned at the age of 25-28 days. In order to ensure the normal growth of young rabbits, we should do a good job of "feeding" after opening our eyes. Generally, feeding should be started from the age of 16 days, and a small amount of digestible and nutritious feed should be fed. When you start feeding, you should feed more times, preferably 5-6 times a day.
Artificial aphrodisiac: In actual production, we often meet some female rabbits who refuse to mate for a long time, especially in autumn and winter. In order to make female rabbits mate in estrus, in addition to strengthening feeding management, artificial estrus induction can also be used, that is, 1. Hormone-induced estrus. 2. Chinese medicine aphrodisiac. 3. Sexual attraction.
Increase light: Rex rabbits don't require much light, but insufficient light will obviously affect their reproductive performance. According to the experiment, under the condition of 20-24℃ and complete darkness, the female rabbit has certain fertility, but the conception rate is very low, only about 30% in one mating. If the light is increased to 1.5 watts per square meter and the light time is extended to 1.2 hours, the conception rate of one mating is about 50%. Under the same light intensity, if exposed to 16 hours, the pregnancy rate of female rabbits can reach 65%-70%, and the survival rate of young rabbits can also be significantly improved. Therefore, increasing light intensity and time can obviously improve the pregnancy rate of female rabbits and the survival rate of young rabbits.
Scientific collocation of feed: Rex rabbits are herbivores, and all herbivores raised artificially cannot meet the nutritional needs of Rex rabbits. Therefore, in daily feeding, in addition to feeding some fresh feed in a planned way, full-price pellet feed should be equipped according to a certain proportion. The advantages of complete pellet feed are: it is not frozen in winter and not moldy in summer. Rex rabbits love to eat and have comprehensive nutrition. The formula is:
1, bean cake or soybean meal 15%. 2. Corn 10%. 3. Bran 19%. 4, orange stalk or weed powder 50%. 5, fish meal 3%. 6. Bone meal 1. 5%。 7, salt 0. 5%。 8. Growth promoter and rabbit additive 1%.
Third, strictly control farming. At present, 70% of rex rabbits raised in China are imported from France or the United States. Due to the slow progress of purification breeding, the deterioration of variety performance and the decline of fur quality, the breeding period must be five mismatches.
1, male and female rabbits are not suitable for age. 2. The general department is not clear. 3, the sick are not worthy. 4. The genetic performance is unstable. 5, does not meet the requirements of directional breeding.
Fourth, the prevention and control of epidemic diseases ① It is necessary to clean rabbit cages and rabbit houses frequently and timely, and do a good job in environmental sanitation. Disinfect once every 10 day in summer and once every 1 month in winter. Disinfection products has Lysol, disinfectant, caustic soda, etc. (2) Use liquid medicine in spring, summer and autumn (trichlorfon 3%, trichlorfon 0. 0 1%, interlayer 0. 0 1%) once a time to prevent dermatosis, tinea pedis, tinea auris and other diseases. ③ Epidemic prevention. Rabbits are injected with rabbit plague vaccine and Pasteurella vaccine 3-4 times a year to enhance the self-resistance of rex rabbits and improve and accelerate their growth and development.
Several key techniques to be paid attention to in rex rabbit breeding
Rex rabbit is a famous fur rabbit in the world. It was formed in 19 19 by the mutation of a nest of French meat rabbits. Because its whole body is densely covered with silky fluff, which is smooth and beautiful, elastic and not easy to fall off, it can be compared with otter skin, so it is also called Rex Rabbit in China. Although rex rabbit has high economic value, it can't get due benefits if it is not properly raised and managed. The following are several key technical problems that should be paid attention to in rex rabbit breeding.
First, understand habits. Because rex rabbit is mutated from common meat rabbit, its basic biological characteristics are not essentially different from meat rabbit. For example: timid, staying up late; Like dry, afraid of wet; Cold and heat (the optimum temperature is 15 ~ 25℃, and the critical temperatures are 5℃ and 30℃); I like cleanliness, but I am afraid of filth; Like vegetarians (herbivores) and hate meat; Same-sex aggression; Love to bite, love to make holes, etc. Compared with meat rabbits, it is more delicate, has poor disease resistance, is prone to rhinitis, enteritis and other diseases, has a slower growth rate, a smaller body shape, a longer feeding cycle, and requires higher nutrition, so it is not suitable for extensive feeding; Rex rabbit is a mutant in coat traits, and coat traits are prone to variation and degradation, so it is necessary to strengthen breeding. Knowing this is very important for raising rex rabbits.
Second, breeding improved varieties. China is the country with the largest number of rex rabbits in the world, but the origin of rex rabbits mainly comes from the United States, Germany and France. It is customarily called American Department, German Department and Legal Department. In principle, they are different crystal systems of the same variety. Due to different culture conditions and directions, these three strains have their own characteristics. For example, beautiful rabbits have the highest adaptability, disease resistance and fertility, but they are small in size and have great individual differences; German rabbits are big and grow fast, but their adaptability and fecundity are poor. French rabbits have the advantages of both American and German, but the introduction time is the shortest and the number is small, so it is still necessary to strengthen feeding and adaptive exercise. For breeders, because the fur of rex rabbit is expensive, there is no need to force it to be crystalline, as long as it is good. It is necessary to emphasize the usual upbringing. The offspring of a good species are not necessarily good. Only by selecting the best from the best and persevering for five generations in a row will we cultivate excellent groups. Pay attention to coat density, coat smoothness and coat length when breeding; Early growth rate and feed reward; Disease resistance, litter size, breastfeeding and motherhood. It is necessary to establish a complete pedigree file and carry out breeding work under the guidance of experts.
Third, pay attention to nutrition. Rex rabbit fur is expensive, and fur growth needs more nutrition. Protein needs more than other rabbits, especially sulfur-containing amino acids (methionine and cystine). Rex rabbits can't be raised well without nutrition as the foundation.
Fourth, the scientific composition. With the nutrition standard, it is necessary to make a reasonable collocation according to the feed varieties, nutritional characteristics and feed prices in different regions. For the convenience of breeders, the author designed a set for reference:
Formula of pregnant female rabbit (%): Sophora leaf powder 7, corn stalk 5, soybean stalk 23, corn 39.8, soybean meal 12, soybean 5, bone meal10.5, fish meal 2, shellfish powder 0.5, sesame cake 3, salt 0.5, Le Tu 0.5 and methionine 0./kloc.
Formula (%) of lactating female rabbits: Sophora japonica leaf powder 9, soybean stalk 25, corn 36.5, soybean meal 12, fried soybean 10, bone meal10.5, fish meal 2, shellfish powder 3, salt 0.5 and Le Tu 0.5.
Feed formula for fattening rabbits (%): Sophora japonica leaf powder 6.5, soybean straw 22.5, corn 38, soybean meal 12.74, wheat bran 5, soybean 7, bone meal 1.3, fish meal 1.5, shellfish powder 0. 16.
Formula of supplementary feed for rabbits (%): Sophora japonica leaf powder 10, soybean straw 10, corn 38, soybean meal 18, wheat bran 6.9, soybean 12, bone meal 1 0.2, fish meal 3 and salt 0.5.
Formula (%) of empty pregnant female rabbit: Sophora leaf powder 8, corn stalk 5, soybean stalk 23, corn stalk 3 3, soybean meal 8, wheat bran 1 1, soybean 5, bone meal 1, flax cake 2.5, cotton kernel cake 2.5, salt 0.5 and rabbit joy 0.5.
Fifth, weight control. The bigger the rabbit, the better. If the breeding rex rabbits weigh more than 5 kg, then their reproduction rate is definitely not high. Whether it is a male rabbit or a female rabbit, the weight should be properly controlled. According to the author's experience, the average weight can reach 3.5 ~ 4 kg. Of course, some rabbits can't grow to this weight in three years, so they can't keep their seeds. For reserve rabbits with growth potential, we should adopt the strategy of early promotion and late control, and don't let their weight gain indefinitely in the later period. Generally, the method of limiting feeding is adopted, that is, after reaching a certain weight, the daily feeding amount is controlled at about 85%. For breeding rabbits in the breeding period, it is necessary to control the fat situation and prevent obesity. It is the same reason that chickens are fat and don't lay eggs as rabbits are fat and don't have children.
Sixth, birth control. First, control the childbearing age. Generally speaking, it is not good to breed rabbits at the age of about 6 months, either too early or too late. Second, control the breeding frequency. Rabbits have great reproductive potential. Theoretically, they can have more than 65,438+00 fetuses a year. However, due to limited production conditions, they can only breed about five fetuses. Therefore, continuous and frequent copying is not desirable. This will cause the early dysplasia of rabbits, affect the differentiation of hair follicles and the quality of skin extension, which is even more useless for breeding rabbits; Third, control the breeding season. Breeding rabbits are afraid of heat, especially male rabbits and female rabbits in the third trimester. The high temperature in the south of North China in the next season is not suitable for rabbits to breed. In rabbit farms without temperature control, it is best to stop breeding in summer; Fourth, control the number of each nest. Rex rabbits have different litter sizes. The high yield can reach more than a dozen, up to more than 20, and the feeding ability is limited. In order to cultivate excellent breeding rabbits and commercial rabbits, it is advisable to raise no more than 8 rabbits per fetus. For offspring rabbits, six rabbits are enough.
Seven, the fattening of commercial rabbits. Coat density refers to the number of hair fibers per unit skin surface. It depends on the differentiation of hair follicles. The differentiation of hair follicles has its special rules. According to the author's research, hair follicles differentiate strongly early after birth. If the nutrition is satisfied, the coat density can be greatly improved. Hair follicle differentiation was slow after 3 months, and basically ended after 5 months. At this time, no matter how high the nutrition is, it will not help. Therefore, it is very important to cultivate commercial rex rabbits at an early stage. In management, we should pay attention to the following points: First, strengthen environmental control. For example, the temperature should be kept between 15 ~ 25℃, and the temperature can be appropriately lowered in the later stage of fattening to improve the quality of fur; The humidity is controlled at about 60%; The density is appropriate, and it is appropriate to raise 10 ~ 14 fattening rabbits per square meter of cage bottom area; There should be some light, but no strong light is needed; Strengthen ventilation to keep the rabbit house fresh; Maintain cage hygiene, environmental hygiene and rabbit health; Environmental control (temperature, humidity, density, light, ventilation, sanitation). Second, improve the breeding technology. The best feed form is pellet feed, and the method of free feeding can improve the weight gain speed. Where there are no conditions, the powder can be wet mixed and the feed can be kneaded into a ball in your hand. There is water in my fingers, but it doesn't drip outside. Just let go of the cracks, feed regularly, and feed less; When rabbit farmers raise rabbits, in the green feed supply season, they can adopt the method of giving priority to green feed during the day and supplementing concentrate at night to save feed costs; Third, free drinking water.
Eight, reasonable skin. A good rabbit produces good skin, but if it is not taken well, all previous efforts will be in vain. Because of the age and seasonality of rex rabbits molting. For underage rex rabbits, age-related molting is obvious. A large number of studies show that before 5 months old, the skin plate is immature, the fur falls off incompletely, and the skin taken is not good; Adult rabbits change seasons twice a year, namely March-May in spring and September-165438+1October in autumn. It is not easy to remove the skin when molting. The quality of skin graft is the best in winter. Most rex rabbit skins come from young rabbits about 5 months old. Due to the cost of breeding, it is impossible for all commercial rabbits to take their skins in winter. In principle, it can be taken at any time, as long as it is 5 months old and weighs more than 2.5 kilograms. Avoid knife injury when taking skin.
Nine, leather goods storage. Improper storage of hides can also cause losses. Preserve the skin after taking it out (divided into salt-dried and sweet-dried, that is, salt-cured or dry-cured). The treated hides should be classified according to their grades and colors, and laid flat, with hair facing each other and head and tail connected. Naphthalene powder should be removed every 2-3 sheets to prevent insects from eating. The warehouse should be sanitary, with a humidity of 50 ~ 60% and a temperature of about 10 ~ (2), and the maximum temperature should not exceed 30℃. Animal skins should be stacked on boards, not directly on the concrete floor. In the process of storage, check it regularly and keep it properly. Stay away from the sun, rain and insects, and avoid the occurrence of old skin, smoked skin, moldy skin and stuffy skin.
X. prevention and treatment of diseases. There are many diseases in rex rabbits, but the diseases that have great influence on them are mainly viral hemorrhage, infectious rhinitis, pasteurellosis, mange, coccidiosis, dermatomycosis and enteritis.
1. Viral bleeding. Commonly known as rabbit plague, it is an acute, febrile and septic infectious disease caused by virus. It has the characteristics of strong infectivity, acute onset and high mortality. And it is often an explosive epidemic, which poses a great threat to the rabbit industry. The disease can occur all year round, especially in spring, autumn and winter. Different ages have different manifestations, and lactating rabbits have no diseases. The susceptibility of young rabbits to the disease gradually increased after 2 months of age, and the susceptibility of young rabbits and adult rabbits was the highest.
Prevention and treatment: At present, there is no good method to treat the disease, and the most ideal method is immunization. From 35 to 40 days after weaning, rabbits were injected subcutaneously 1 ml of rabbit plague vaccine behind the neck and ear, and the immunization was once at the age of 60 days, and the immunization period was 4 to 6 months. Other rex rabbits can be immunized three times a year.
2. Infectious rhinitis. It is a chronic infectious disease in rabbits caused by Pasteurella, Bordetella and other pathogenic bacteria, characterized by closing eyes. The disease can occur all year round, but the incidence rate is higher in spring and autumn when the climate is changeable. All rabbits are susceptible, and young rabbits are the most susceptible. The incidence of rabbits raised indoors is higher than that raised outdoors, especially in rabbit houses where harmful gases are increasing.
Prevention and control measures: rabbits should be purified where conditions permit. The rabbits with positive rhinitis were excluded, and the whole group was given 0.3 ~ 0.5% bright green solution. After 20 hours, the rabbits with rhinitis were infected and excluded. Strengthen environmental control. According to research, the occurrence of infectious rhinitis is directly related to environmental conditions, especially the high concentration of harmful gases in rabbit huts, which will induce rabbits to suffer from rhinitis. Therefore, try to make the rabbit house ventilated and fresh; Drug control. In the changeable season, some preventive drugs, such as oxytetracycline, sulfonamides, ciprofloxacin, etc. , feed regularly; You can also regularly feed medicinal plants such as garlic. Chloramphenicol, kanamycin, penicillin and streptomycin can be used in nasal drops, and olaquindox 200 mg/kg can be added to feed, all of which have good effects. Experiments in recent years show that "Bi 'anjing" developed by Mountain Research Institute of Hebei Agricultural University has a good prevention and treatment effect on this disease. 0.5% feed prevention, 1% treatment for 3 days.
3. Coccidiosis. Coccidiosis is a common parasitic disease in the body, which is caused by many coccidia of Eimeria, and is the most harmful to young rabbits. All kinds of rabbits are susceptible, and the morbidity and mortality of young rabbits weaned to 3 months old are the highest. Adult rabbits tolerate this, but do not produce immunity, and become long-term carriers and sources of infection. It can happen all year round, but it is most serious in summer with high temperature and humidity.
Preventive measures: reducing infection and crossing the river: the mother rabbit is the source of coccidiosis, reducing the chance of contact between the offspring and the mother rabbit, breastfeeding regularly, cleaning and disinfecting the mother rabbit cage frequently, and accumulating and fermenting its feces; Washing, rubbing and applying 2% medical iodine tincture to the mother rabbit's breast before breastfeeding have good effects.
Drug prevention: The better drugs are chlorpheniramine, dijunjing, sulfonamides, salinomycin, etc. , add according to the instructions; "Qiujing" developed by Mountain Research Institute of Hebei Agricultural University was added with 1% feed for prevention, and stopped taking medicine for 5 days in 15 days. The feed dosage of 1.3 ~ 1.5% was added for 5 days, which was a preventive dosage and had a good effect.
4. scabies. It is a highly contagious ectoparasitic disease caused by scabies and itchy mites, also known as scab disease, calcareous foot disease and claw disease, which poses a great threat to rabbit industry.
Prevention and control measures: regular testing and frequent disinfection of drugs. Conduct a comprehensive inspection of rabbits every year, and isolate the suspicious rabbits in time and take measures. Rabbits are not imported from a rabbit farm suffering from mange, and can be mixed after 3 weeks of observation. The rabbit house should be disinfected frequently to keep the environment dry, ventilated and sunny.
The ideal medicine and method are: apply 2 ~ 2.5% trichlorfon alcohol solution to the affected area; Intramuscular injection of insecticide or insecticide, 0.2ml per kg body weight, or oral insecticidal powder, 0.2mg per kg body weight.
5. dermatomycosis. Infectious dermatoses caused by Trichophyton mentagrophytes and Microsporum characterized by depilation, hair breakage and skin inflammation.
Preventive measures: strengthen feeding management, pay attention to ventilation, keep rabbits and the environment clean, often disinfect the air, and isolate and treat rabbits in time if they are found. The following drugs can be used for treatment.
A large group of patients were given griseofulvin orally, 25 mg per kilogram of body weight every day for 2 weeks. Clotrimazole liquid or ointment is evenly applied to the affected area, 3-4 times a day, until it is cured; 10% salicylic acid ointment, or 2% formalin ointment, or 5 ~ 10% copper sulfate aqueous solution is applied to the affected area 2 ~ 3 times a day until it is cured.
6. enteritis. It is an infectious disease caused by a variety of pathogenic bacteria, which is characterized by dysfunction of digestive tract system and discharge of loose stool, mucus stool or bloody stool. It is very harmful to rex rabbits, especially young rabbits. There are many pathogenic bacteria that cause enteritis, such as Escherichia coli, Salmonella, Pasteurella, Clostridium welchii, Tazella, Klebsiella, rotavirus, coccidia and so on.
Preventive measures: In view of the above reasons, take corresponding preventive measures. Except coccidia and rotavirus, most of them are caused by bacteria. Prophylactic norfloxacin, furazolidone, ciprofloxacin, olaquindox, chloramphenicol, etc. It can be added to feed and used for 3-5 days according to the instructions.
Treatment can be intramuscular injection of bacillary dysentery, chloramphenicol, sulfadiazine sodium, etc. Feeding with nasal anal net has a good preventive effect. Due to the fragility of the digestive tract of rex rabbits, once enteritis occurs, it is easy to dehydrate, electrolyte imbalance and poisoning. In order to achieve the ideal therapeutic effect, fluid replacement and detoxification should be combined at the same time. Such as intravenous injection of glucose, intramuscular injection of vitamin C and so on.
Normal rex rabbits have good spirits, flexible ears, keen sense of smell, bright eyes, keen reaction, natural posture, coordinated movements, even breathing, normal weight and bright fur. The sick rabbit looks listless. Head and ears drooping, lying still, stumbling, loss of appetite, unkempt hair, dull eyes, gum, burning or cold ears, shortness of breath, sneezing, etc. After finding the sick rabbit; It is necessary to isolate the breeding, analyze the reasons and prescribe the right medicine. Mainly from the following three aspects to find the reason:
1, whether the feed in the feed factory is hygienic and not moldy: whether the ratio of forage to concentrate is appropriate, and whether the grass is hygienic does not replace dew. All the above conditions will lead to the onset of rex rabbits.
2. Hygiene: Whether the pens and environmental sanitation are kept clean and dry, it is necessary to remove the feces in time and use disinfectants such as the first poison to remove the poison. The ground can be disinfected with lime.
3. Management: prevent the disease from entering the mouth, feed it regularly and quantitatively, strengthen feeding management, keep it clean and hygienic, do a good job of vaccination, and isolate the disease in time.
Preventive measures:
A, ensure the feeding with reasonable feed, and no mildew, no poison, no smell.
B, strict management, adhere to the disinfection and epidemic prevention.
C, pay attention to take corresponding emergency measures when the weather changes suddenly, prevent heatstroke in hot days and keep warm in cold days.
D, rex rabbit common diseases are:
Coccidiosis lengthi: It mostly occurs in warm and humid seasons, and mainly harms 1-4-month-old rabbits. Symptoms: listlessness, loss of appetite and slow action. The secretion of eyes, nose and saliva increases, anemia, emaciation, diarrhea and constipation appear alternately, the anus and limbs are polluted by feces, sometimes the abdomen swells at the sight of blood, the intestine is full of gas, the limbs are paralyzed, twitching, screaming and dying soon.
Treatment: chlorpheniramine, coccidia powder, Vitex negundo, and prevention according to the instructions.
2. Symptoms of scabies: first, the ears, nose and mouth are red and swollen, and thick liquid flows, and then the scab skin spreads to the whole body, causing systemic inflammation and death, and the sick rabbit is violently uneasy, scratching with his toes, biting with his mouth or rubbing to relieve itching; A series of phenomena such as nodules, blisters and local hair removal appeared in the affected area. Severe death due to anemia, emaciation and exhaustion.
Treatment: Chlorpyrifos (0.2mg/kg body weight) was injected subcutaneously or orally into the neck and applied to the affected area.
3, gastroenteritis: Rex rabbits swallow moldy and deteriorated feed or grass with dew, or the enclosure is too wet. Symptoms: loss of appetite and mental paralysis in sick rabbits; Diarrhea or constipation, gradually emaciation, and finally collapse and die.
Treatment: oxytetracycline or furazolidone is mixed with ingredients for 2-3 days according to the instructions.
