(1) Clinical symptoms can be divided into three types.
The most acute type: sudden death without any obvious symptoms. There are many short-lived excitement before death, such as screaming, struggling, twitching, running and so on. Some rabbits shed foamy blood from their nostrils before they died. Most of these cases occurred in the early stage of the epidemic.
Acute type: listlessness, rough fur and rapid weight loss. When the body temperature rises above 4 1℃, the appetite decreases or disappears, and the desire to drink alcohol increases. Suddenly excited before he died, he fell to the ground with a scream and died. The above two types mostly occur in young rabbits and adult rabbits. The anus of the diseased rabbit was slack before death, and there was a small amount of yellowish sticky loose stool.
Chronic type: more common in late epidemic or weaned rabbits. Elevated body temperature, listlessness, aversion to food, love to drink cold water, emaciation. The course of disease is more than 2 days, most of them can be cured, but they are still carriers and infect other rabbits.
(2) Pathological changes
The dead rabbits showed systemic septicemia with bleeding, congestion and edema in various organs. The lungs are highly edematous, with bleeding spots of different sizes, and a large amount of red foamy liquid flows out of the section. Congestion or diffuse bleeding of throat and tracheal mucosa, especially tracheal ring; Liver swelling and degeneration, khaki, or purple congestion, bleeding point; Renal enlargement is purplish red, often mixed with pale degeneration areas and spots, and some see needle bleeding; Blood vessels in brain and meninges are congested, and there are blood clots in pituitary and pineal gland; Thymus bleeding.
(3) Prevention
There is no specific drug treatment for this disease, and vaccination is the best way to prevent rabbit plague. After weaning, each rabbit was injected subcutaneously with 1 ml, and the immune period was 4 ~ 6 months after 5 ~ 7 days. Adult rabbits were injected 2 ~ 3 times in 65438 0 years, each time 1 ~ 2ml. Once rabbit plague occurs, immediately block the rabbit farm, isolate the sick rabbits, bury the dead rabbits, and thoroughly disinfect the cage, rabbit house and environment; When necessary, each uninfected rabbit is injected with 2 ~ 3 ml. Rabbit farms in the onset period shall not sell rabbits to the outside world, nor shall they be introduced from epidemic areas.
2. Infectious stomatitis
This disease is an acute infectious disease caused by virus, usually called salivation.
The clinical symptoms of (1) mainly affect rabbits aged 1 ~ 3 months. At the beginning of the disease, the oral mucosa was red, and then blisters as big as millet and peas appeared in many parts of the mouth. After the bubble bursts, it forms rotten spots and drools a lot, which makes the chin, moustache, neck, chest and front paws wet. Rabbits are depressed and can't eat. Some rabbits have high body temperature and diarrhea. The course of disease is 2 ~ 10 days, and the mortality rate is over 50%.
(2) The prevention and treatment of infectious stomatitis is mainly through digestive tract infection. Improper feeding, feeding moldy feed, oral injury, etc. are all inducements, which mostly occur in spring and autumn. Therefore, targeted preventive measures should be taken. Usually pay attention to the sanitation and disinfection of rabbit houses and strengthen feeding management. Individual rabbits were isolated and treated immediately. You can rinse your mouth with 2% boric acid water, 2% alum water or 0. 1% potassium permanganate water, and then sprinkle Scutellaria baicalensis powder and boron ice powder in your mouth. Or 7 parts of alum and 3 parts of white sugar, and the mixture is smeared in the mouth three times a day without drinking water for half an hour. For rabbits with serious illness, sulfonamides can be given at the same time, and symptomatic support treatment can be taken.
3. hemorrhagic septicemia
This disease is caused by Pasteurella multocida. This pathogen is a conditional pathogen, that is, 30% ~ 70% of healthy rabbits have this pathogen in their nasal mucosa and tonsils, and they do not get sick at ordinary times, but get sick when their condition deteriorates or their resistance decreases.
(1) Cause the temperature changed suddenly, rising and falling suddenly; The air in the rabbit house is dirty, humid and poorly ventilated; Rabbits are crowded and transported for a long distance; Poor feed quality and improper feeding management; Other diseases or any stress can lead to the decline of disease resistance, bacterial reproduction and increased virulence in rabbits, leading to diseases. It can occur all year round, especially in spring and autumn, which is sporadic or endemic.
(2) The main type of rhinitis: nasal mucus in rabbits, which is serous at first, and then gradually becomes mucinous and purulent. Rabbits often sneeze and cough, scratching their nostrils with their front paws. After a long time, the nose thickens, forms scabs, blocks the nostrils, and has difficulty breathing. Because rabbits often scratch their noses, they will bring germs into their eyes and under the skin, causing conjunctivitis and subcutaneous abscess.
The course of rhinitis is long, even exceeding 1 year for several months. But it is highly contagious and poses a great threat to rabbits. At the same time, because the disease is easy to deteriorate, it can induce other diseases and die.
Pneumonia type: often transformed from rhinitis type. At first, the symptoms are anorexia and depression, then the body temperature rises, breathing is difficult, and sometimes diarrhea and arthritis occur. Some died suddenly, and some delayed the course of disease 1 ~ 2 weeks. Lesions can spread to any part of the lung, showing consolidation (liver degeneration), emphysema, abscess and small gray nodular lesions, pulmonary parenchyma bleeding, and pleural surface covered with cellulose.
Sepsis: this type can be secondary to other diseases or occur alone, and the most common type is septicemia mixed with rhinitis and pneumonia. Sick rabbits have listlessness, loss of appetite, shortness of breath, body temperature rising above 465438 0℃, runny nose and sometimes diarrhea. Before he died, his body temperature dropped and his limbs twitched. The course of the disease was as short as 24 hours and as long as 3 to 5 days. The most acute cases often fall to the ground suddenly and have no clinical symptoms.
Lesions can be seen, and there is no obvious naked eye change in patients with short course of disease. During the course of the disease, the respiratory mucosa of the elderly is congested and bleeding, and there are many blood bubbles. Severe congestion, bleeding and edema in the lungs; Liver degeneration, necrosis focus is more; Spleen and lymph nodes are swollen and bleeding, and there are bleeding spots on endocardium and epicardium; There is yellowish effusion in the chest and abdomen. In some cases, there is abscess in the lung, and cellulose is attached to the surface of chest cavity, abdominal cavity, pleura and lung.
Otitis media type: also known as crooked head and torticollis, is the result of the spread of germs from the middle ear to the inner ear and brain. In severe cases, they roll in the direction of tilting their heads until they are blocked by objects. These rabbits have a poor diet and lose weight, but rarely die in a short time. Lesions can be seen, and there is white creamy exudate in one or two tympanic cavities; When the infection spreads to the brain, purulent meningitis may occur.
Conjunctivitis type: The clinical manifestations are tears, conjunctival congestion, eyelid swelling and secretion sticking to the upper and lower eyelids. In addition, there are metritis, orchitis, abscess and enteritis.
(3) Prevention and control
Rabbit farms insist on self-propagation and self-support, and the introduction from other places needs strict quarantine; Strengthen feeding management at ordinary times, improve sanitary conditions, pay special attention to ventilation and regular disinfection; Pasteurella inactivated vaccine, injected 1 ml each time, produces immunity in 7 days, and the immune period is 4 ~ 6 months, and injected 2 ~ 3 times a year; In conditional rabbit farms, rabbits are smeared with 0.2% ~ 0.3% bright green water solution one by one every year, and 2 ~ 3 drops are smeared on each nostril. After 18 ~ 24 hours, rabbits with white purulent secretion around their nostrils were all Pasteurella-carrying rabbits. After testing, they are isolated, raised, treated or destroyed. The treatment can be mixed intramuscular injection of penicillin and streptomycin, with a weight of 65,438+0,000 ~ 20,000 units per kilogram, twice a day for 3 ~ 5 days; 0. 1 ~ 0.2g sulfadiazine sodium was injected intramuscularly per kg body weight twice a day for 3 ~ 5 days. Oxytetracycline, chloramphenicol, gentamicin, sulfonamides, olaquindox and ofloxacin can also be used. For rhinitis, drugs (such as chloramphenicol, penicillin+streptomycin, chloramphenicol+aminophylline, gentamicin+nasal drops, 4 times a day for 3 ~ 5 days) combined with nasal cavity and muscle injection or oral administration have obvious effects.
4. Clostridium welchii disease
This is an acute fatal enterotoxemia characterized by severe diarrhea caused by Clostridium welchii type A and its toxin.
(1) etiology
Clostridium welchii widely exists in soil, sewage, feces, low-quality feed (such as inferior fish meal) and human and animal intestines. When the sanitary conditions are poor, the feeding management is poor, the feed changes suddenly, the mix is improper, and the crude fiber is insufficient, the internal environment of the rabbit intestine changes, the normal flora of the intestine is destroyed, and some harmful bacteria (such as Clostridium welchii, etc. ) multiply and produce toxins, leading to rabbit poisoning and death. The route of infection is digestive tract, skin and mucous membrane damage, which can occur all year round, especially in spring, autumn and winter. Rabbits of all ages get sick, especially young rabbits and young rabbits.
(2) Clinical symptoms
Acute cases suddenly attack, acute diarrhea, and die soon. Some sick rabbits were depressed, lost appetite or did not eat, and their feces were not formed. They quickly become bloody, peptone-like, black or brown, and have a foul smell, polluting the hindquarters. Rabbits are severely dehydrated, their intestines are full of gas, their limbs are weak, they are unconscious and gradually die. Some sick rabbits twitched before they died, and some were suddenly excited and screamed and died. In most cases, it takes about 10 hour from the appearance of deformed feces to death.
(3) Diagnostic points
Sudden severe watery diarrhea and acute death; The food in the stomach is full, the gastric mucosa falls off, and there are many bleeding points and ulcer points; The small intestine swells and is filled with peptone-like liquid; There is diffuse congestion or strip bleeding in the serosa and mucosa of cecum, which is full of brown contents and sour gas; The liver is brittle, the gallbladder is swollen, and the blood vessels on the heart surface are angry and congested. There is a small amount of brown urine in bladder muscle.
(4) Prevention and control
Strengthen sanitation and disinfection and feeding management at ordinary times, and pay attention to the reasonable collocation of feed, especially crude fiber; Do a good job in food hygiene, and it is forbidden to feed moldy and deteriorated feed, especially inferior fish meal.
Rabbits are regularly injected with Clostridium welchii vaccine A, which can be injected after weaning, and then injected 2 ~ 3 times a year.
Once sick rabbits appear, they should be isolated immediately and given drugs (such as chlortetracycline, erythromycin, kanamycin, olaquindox, ciprofloxacin, etc.). ), and give emergency vaccination.
For the affected rabbits, antibacterial, anti-inflammatory, rehydration and detoxification should be carried out at the same time. The author used oral perfusion of 200,000 units of penicillin, 200,000 units of streptomycin, 20 ~ 50 ml of glucose and physiological saline, and intramuscular injection of vitamin C 1 ml twice a day for 3 ~ 5 days, and the effect was good.
5. Staphylococciosis
This disease is caused by Staphylococcus aureus and is characterized by purulent inflammation. Staphylococcus widely exists in nature and can cause many diseases.
(1) Main types
Mastitis type: it is common in the first few days after delivery of female rabbits.
In acute stage, the rabbit's body temperature rises, and the breast is swollen, purple, burning and painful, and the milk is mixed with purulent blood; In chronic cases, lumps of different sizes are formed locally in the breast, and finally an abscess is formed. Foot dermatitis type: the bottom of rabbit hind legs began to appear depilation, redness and swelling, and then formed abscess, ulceration, and finally became ulcer surfaces of different sizes.
Abscess type: occurs under the skin of any part and in any organ. Subcutaneous abscess is mostly caused by trauma, which can be wrapped by connective tissue capsule and rupture by itself after maturity. Visceral abscess can affect its function, often causing systemic infection, becoming septic septicemia and leading to rapid death.
Young rabbit enteritis type: also known as young rabbit yellow urine disease, is caused by young rabbits sucking the milk of female rabbits suffering from mastitis and discharging yellow feces. The rabbit was as soft as mud and unconscious, and died in 2 ~ 3 days.
In addition, young rabbits have sepsis and rhinitis.
(2) Prevention and control
The occurrence of staphylococcosis is mostly caused by poor sanitary conditions and mechanical damage. Therefore, it is necessary to do a good job in environmental sanitation, eliminate all sharp objects in the house, especially in cages, and prevent rabbits from biting each other. In order to prevent mastitis, female rabbits can be fed with compound sulfamethoxazole 1 tablet every day (twice) for 3 days. In the first few days after delivery, the amount of concentrated feed can be reduced to prevent excessive secretion of mammary glands; Foot dermatitis should work hard on seed selection and choose seeds rich in foot hair. The material of cage bottom pedal is directly related to foot dermatitis, and flat bamboo board is better than barbed wire. For large varieties, you can put a board of moderate size in the cage, which has a good effect on relieving the disease.
The female rabbit mastitis can be intramuscular injected with penicillin twice a day, each time with 654.38+ 10,000 units. Severe rabbits can use 2 ml of 2% procaine, 8 ml of water for injection, and dilute1.20,000 ~ 0.20,000 units of penicillin for breast sealed subcutaneous injection; If an abscess has formed, it can be cut and drained, washed with hydrogen peroxide, and finally coated with some antibacterial and anti-inflammatory drugs; At present, there is no good treatment for foot dermatitis, and protection should be given priority to with external antibacterial drugs. Severe cases can be intramuscular injection of penicillin; For rabbits with mild xanthuria, chloramphenicol or gentamicin can be dropped into the mouth 3 ~ 4 times a day.
6.colibacillosis
It is an intestinal infectious disease caused by a certain serotype of pathogenic Escherichia coli and its toxin. It can occur all year round, and rabbits of all ages are susceptible, which poses the greatest threat to weaned to 4-month-old rabbits.
(1) The main clinical symptoms and anatomical features are diarrhea with yellowish brown watery stool. Acute cases usually die in 1 ~ 2 days, and subacute cases die in 1 week. Normal or low body temperature, abdominal swelling, drums and running water. The rabbit feels cold in the limbs, grinding his teeth and salivating.
Autopsy showed that the liver was swollen and fragile; Pneumonia edema with hemorrhage; The gastric mucosa falls off, and there are dark brown ulcer spots of different sizes on the gastric wall; The serosa and mucosa of colon and cecum are congested or bleeding, and the intestine is filled with gas and peptone. In some cases, the liver and heart have focal necrosis.
(2) Prevention
This disease is directly related to feed and hygiene. Feed should be reasonably matched to ensure a certain amount of crude fiber, energy and protein level can not be too high; Don't change the feed suddenly, there should be an adaptation period of about 7 days; Strengthen food hygiene and environmental hygiene to eliminate the pollution of feed and drinking water by mosquitoes, flies and rats; For weaned rabbits, some drugs can be added to the feed, such as furazolidone, olaquindox, norfloxacin or chloramphenicol. 0.5% ~ 1% microecological preparation was added to the feed for 5 ~ 7 days; For rabbit farms where the disease often occurs, the Escherichia coli isolated from this farm can be made into inactivated aluminum hydroxide vaccine for prevention, and each rabbit aged 20 ~ 30 days can be injected with 1 ml, which can effectively control the occurrence of the disease.
(3) treatment
Spiramycin, 20 mg per kg body weight per day, intramuscular injection; Polymyxin E, 0.5 ~ 1 mg per kg body weight per day, intramuscular injection; Gentamicin, 1 ~ 1.5 mg/kg body weight, intramuscular injection, three times a day (the effect of alternating application or combination of the above three is better); Kanamycin sulfate, 5 mg per kg body weight, intramuscular injection, 3 times a day; Enrofloxacin, 0.25 ~ 0.5ml/kg body weight, intramuscular injection, twice a day, for 3 ~ 5 days. In order to improve the therapeutic effect, it should be carried out simultaneously with fluid replacement.
7. Coccidiosis
Coccidiosis is a common parasitic disease in vivo, which is caused by many species of Emilia coccidia and is very harmful to young rabbits. All kinds of rabbits are susceptible, especially the young rabbits weaned to 3 months old have the highest morbidity and mortality. Adult rabbits have strong resistance to coccidia and can generally tolerate it, but they cannot produce immunity and become long-term carriers and sources of infection. It can happen all year round, especially in high temperature and high humidity season.
(1) Clinical symptoms
Anatomical features Coccidiosis in rabbits can be divided into intestinal type, hepatic type and mixed type. At the early stage of the disease, the rabbit suffered from loss of appetite, mental depression, abnormal digestive function, alternating diarrhea and constipation, emaciation, bloating, blue abdomen, loss of appetite, sudden fall to the ground, limb twitching, head leaning back and screaming to death; Or limb spasm, paralysis, failure and death.
The small intestine of rabbits died of enterococcus was light gray, and there were many white induration under the serosa of earthworm. Liver-type rabbits have hepatomegaly, with gray-white or yellowish lesions of different sizes on the surface and inside, and creamy mucus inside. Abdominal effusion. Saturated saline floating method and microscopic examination showed that there were a large number of ovoid coccidia eggs in feces or intestinal contents.
(2) Prevention
This disease is mainly caused by oral infection. Infected rabbits and diseased rabbits are the source of infection, and warmth and humidity are the necessary conditions for the disease. Therefore, the key lies in early prevention. Separate feeding for mother and baby, and regular breastfeeding to reduce the chance of contact between mother and baby; Strengthen the disinfection of rabbit houses and pets, clean up feces in time, and pile them up for fermentation; Applying medical tincture of iodine to mother rabbits' nipples before breastfeeding can not only directly disinfect and kill insects, but also make young rabbits get some iodine during breastfeeding, thus inhibiting coccidiosis. In the onset season, some drugs are often mixed in feed, such as chlorpheniramine, dijunjing, Keqiu powder, furazolidone, sulfonamides and so on. Several drugs (such as chlorpheniramine, dijunjing, Keqiu powder, salinomycin, sulfonamides, etc. ) Alternate feeding can be selected.
Some traditional Chinese medicines also have good preventive and therapeutic effects on coccidiosis. Rabbit farms that have used several drugs for a long time sometimes find that the drug effect is not good. The author chose "Qiujing" (developed by Mountain Research Institute of Hebei Agricultural University) for dozens of such rabbit farms, added 1% feed for prevention, and used it continuously for 15 days, which controlled the development of the disease and achieved good results.
(3) treatment
Cloguanidine, 30 mg/kg body weight, fed continuously for 5 days, stopped taking the drug for 3 days, and then changed to preventive dose (15 mg/kg);
Qiu Liling, 50 mg per kg for 5 days;
Salinomycin, 50 mg per kg feed, 1 month;
Furazolidone, 20 mg per kilogram of body weight every day, for 3 ~ 5 days;
Diclofenac, 40 mg per day, feeding for 5 days, stopping taking medicine for 3 days; "Qiujing" is added according to 1.3% ~ 1.5% of the feed, kept for 5 ~ 7 days, and then changed to preventive dosage.
In addition, some traditional Chinese medicines such as onion and garlic also have a good preventive and therapeutic effect on coccidiosis. The prevention and treatment of coccidiosis should adopt cross-medication or "shuttle" medication, and one drug should not be used alone or for a long time; The dosage of the medicine should be sufficient, stirred evenly and used strictly according to the course of treatment.
8. Scabies
Scabies is a highly contagious ectoparasitic disease caused by scale mites and itch mites, also known as "mite", "furuncle", "lime foot" and "dry claw disease", which poses a great threat to rabbit industry.
(1) Clinical symptoms
According to different parasitic parts, it can be divided into tinea corporis (tinea pedis) and tinea auris.
Tinea corporis: It is caused by scabies mites and back anal scabies mites. First of all, the disease starts around the feet, mouth and nose, causing severe itching and pain, which makes the sick rabbit uneasy. Local depilation, exudation of liquid, formation of dry yellow-white scab, skin thickening, chapped, etc. , which often leads to bacterial infection and aggravation. These rabbits suffer from metabolic disorder, which affects their eating and rest, and gradually becomes emaciated, anaemic and eventually dies.
Earringworm: caused by itchy mites. Mainly parasitic in the external auditory canal, puncturing the skin with mouthparts not only absorbs its nutrients, but also secretes toxins, making it itchy. The affected part is red and swollen and oozes exudate, which forms a yellowish brown scab after drying. In severe cases, scabs can block the entire ear canal. The affected rabbits fidgeted, shook their heads, ate and rested, and gradually lost weight and died.
(2) Prevention
The key to this disease lies in early control. Not imported from a sick rabbit farm; The newly introduced rabbits are all prevented by drugs, that is, the 1% ~ 2% trichlorfon aqueous solution is prepared, and 3 ~ 5 drops are dripped into each ear, so that the walls around the ears are stained with the liquid medicine. The rabbit's lower limbs were soaked in the liquid medicine for half a minute, and then they were taken out and tossed. Healthy rabbits 1 ~ 2 times a year, and rabbit farms with diseases not less than 3 times a year. The disease can be controlled for 2 ~ 3 years. Keep the rabbit house dry and sanitary, and disinfect it regularly (flame or 1% trichlorfon is more effective). Found that rabbits were isolated and treated in time.
(3) treatment
There are many drugs and methods for treatment, such as dropping 2% trichlorfon alcohol solution on the affected area every 7 days/kloc-0 times until it is cured; Ivermectin (trade name: Buchongding, Bouguexing, etc. ), intramuscular injection or oral administration, with good effect, is an ideal drug for treating seriously ill rabbits. Chlordimeform, prepared into 0. 15% aqueous solution, medicated bath or sprayed on the affected area; Phoxim, mixed with 0. 1% water solution, applied to the affected area; Coumaphos (16% coumaphos EC 70 times water) was applied to the affected area.
Treatment of scabies should master the following principles:
(1) before taking the medicine, remove the scab skin and drop a few drops of kerosene or diesel oil to make it fall off naturally;
② The rabbit house, rabbit cage, utensils and playground are disinfected simultaneously;
(3) Repeated administration 1 time every 7 ~ 10 days to kill the newly hatched larvae.
9. pica
Some rabbits not only eat normally, but also bite other objects, such as young, wool and dirt. These phenomena are mostly nutritional metabolic diseases, called pica.
(1) main types and etiology
Eating the baby: After the mother rabbit gives birth to the baby, she eats some or all of the baby rabbits. Primiparous female rabbits are the most common, mostly occurring within 3 days after delivery. The main reasons are:
(1) nutritional deficiency, especially protein and mineral deficiency, is easy to feed after delivery;
② The mother rabbit did not drink enough water before and after delivery, licked the placenta and the placenta, and her mouth was dry and sticky. At this time, if she doesn't prepare drinking water in advance, she may eat her young rabbit.
(3) During and after delivery, the female rabbit is highly nervous. If she is frightened by noise, vibration or animals at this time, it will cause mental disorders, and there will be many phenomena such as eating, biting, trampling or abandoning the baby (no longer breastfeeding the bunny).
④ During calving, the surrounding environment or padding has bad smell (such as rat urine smell, musty smell, perfume smell, etc. ), leading to confusion of the mother rabbit and eating the young rabbit as an enemy;
⑤ Once the mother rabbit eats the baby, she will taste the taste of eating the baby, which may recur in the future and form a vicious habit.
Wool eating: in most cases, rabbits have no other abnormal phenomena. At first, only a few rabbits with incomplete hair will be mistaken for depilation. Later, the area of hair loss became larger and larger, and some of them were completely eaten. If you look closely, you will know that it is eating wool. Eating wool is divided into eating by yourself and being eaten by it, and being eaten by it is the main thing. In group breeding, when 1 rabbit eats wool, it will induce other rabbits to follow suit, and often concentrate on eating the same rabbit first. Some eat rabbit hair and tear off the skin. The author thinks that the main reason for eating wool is the lack of sulfur-containing amino acids (methionine and cystine) in feed, and the cold and hot climate is the inducing factor, especially for growing rabbits weaned to 3 months old.
Foot fetishism: rabbits eat their own feet. The author investigated dozens of rabbits suffering from foot feeding, and found that most of them suffered from leg and foot fractures, foot dermatitis and tinea pedis. At this time, the muscles, blood vessels, skin and nerves of legs or feet are damaged to a certain extent, which leads to metabolic system disorder, blood circulation disorder, metabolic products can not be discharged in time, and inflammatory edema appears at the foot end, which stimulates rabbits and makes them hungry.
Soil-eating addiction: rabbits are found licking the soil on the ground when they are free-range, especially the soil at the root of the wall and the alkali chips on the wall. The author found that all rabbit farms with grain were short of salt, calcium, phosphorus and trace elements in feed, so it was considered that it was caused by mineral deficiency.
Wood food: Rabbits eat wooden or bamboo doors, windows and utensils in cages. According to the author's investigation and access to relevant information, this is mainly due to the lack of crude fiber content and hardness of feed, which makes the growing incisors of rabbits wear abnormally.
(2) Prevention and control
Pica is a metabolic disease caused by many reasons. Some are caused by one or several reasons, and some are caused by many factors. It is necessary to analyze the specific situation, find out the reasons and take corresponding measures. Generally speaking, to prevent cannibalism, we should ensure nutrition, provide adequate drinking water, keep the environment quiet and prevent odor stimulation. Female rabbits should not mate in advance when they have not reached the mating age and weight. For female rabbits who have had feeding experience, artificial induction of labor should be carried out and breastfeeding should be carried out under artificial care. Generally speaking, cannibalism will not happen again after 1 week.
The wool-eating rabbits should be isolated in time, the density should be reduced, and 0. 1% ~ 0.2% sulfur-containing amino acids, 0.5% gypsum powder, 1.5% sulfur and trace elements should be supplemented in the feed. Generally, you can stop eating wool in about 1 week.
The key to gluttony is prevention. We should work hard on the pedal. Ensure that the lath is flat and the gap is moderate, and prevent the rabbit's foot from getting stuck in the gap and causing fracture. We should also actively prevent foot dermatitis and tinea pedis. For soil-eating rabbits, adding salt, bone meal and trace elements to feed according to nutritional needs will soon stop.
For wood-eating rabbits, there should be enough crude fiber in the compound feed, and granular feed is recommended for rabbit farms with conditions. Usually, put some twigs or cut fruit branches in the grass rack of the rabbit cage and let them eat freely, which can not only prevent eating differently, but also provide nutrition.
(All the above are transferred from the Internet) Rabbit vaccines are different, and the injection sites are different. According to the instructions of the vaccine, most of them are subcutaneous injections.
