Sick sheep and infected sheep are the sources of infection of the disease. The virus exists in pustules and scabs, and healthy sheep are mainly infected by skin and mucosal abrasions. Contaminated feed, drinking water or sick sheep scabies left on the ground can spread infection.
Epidemic characteristics
Sheep of all breeds and sexes can be infected, but lambs and young sheep (3 ~ 6 months old) are the most susceptible and often popular. Adult sheep have fewer diseases, mostly sporadic. The onset has no obvious seasonality, and it is more common in spring. Moreover, due to the strong resistance of the virus, once the disease occurs, it can often continue to harm for many years.
The incubation period is 4 ~ 7 days. The disease usually forms a characteristic pathological process and symptoms on the skin and mucous membrane of the mouth and lips: it starts with scattered small erythema, and soon forms small nodules with hemp seeds, and then turns into blisters or pustules. After the pustule ruptures, it will form a yellow or brown warty scab. When benign, the hard scab gradually expands, thickens and dries, and the scab skin falls off, and it heals within 1 ~ 2 weeks. In severe cases, the skin lesions spread to cheeks and face, and papules, blisters, pustules and scabs appeared, which interacted with each other.
Fusion, forming a large area of dirty scab; The granulation tissue under the scab proliferates, which makes the mouth and lips swell like mulberries and affects eating. The sick sheep are getting weaker and dying. The course of disease is 2 ~ 3 weeks. Some sick sheep still have the same pathological changes in their limbs and hooves. At this time, the sick sheep limped and could not afford to lie down seriously. The perineum, penis, breast and nipple of a few sick sheep also have the same pathological process.
(1) and sheep pox: acne rash is mostly systemic, protruding from the skin surface in a round shape, with umbilical depression in the middle, obvious boundary, elevated body temperature and serious systemic reaction.
(2) Differentiation from necrotizing bacillosis: The local damage of necrotizing bacillosis is mainly tissue necrosis without blisters, pustules and verrucous growth.
(3) Differentiation from sheep ulcerative dermatitis: Ulcerative dermatitis mainly involves adult sheep, and the lesion is characterized by ulceration and tissue destruction, and there is no mulberry-like granulation tissue under the scab.
The important measure to prevent the disease is not to introduce sheep and livestock products from epidemic areas. If it is necessary to introduce sheep and livestock products, it should be isolated for 2 ~ 3 weeks, and the hoof should be thoroughly cleaned and disinfected many times. To prevent skin and mucous membrane trauma, especially in the teething period of lambs, the oral mucosa is delicate and easy to cause trauma, so avoid feeding spiny grass or grazing on the grass with spiny plants. Add proper amount of salt in time to reduce the chance of damaging skin and mucosa by gnawing soil and wall. After the outbreak of the disease, in addition to thorough disinfection of sheephouses and feeding management tools, the sick sheep should also be treated in isolation, and their body surfaces and hooves should be cleaned and disinfected frequently. In endemic areas, the disease can also be controlled by vaccination.
Goat infectious pustule is also called goat infectious pustular dermatitis, commonly known as sheep's mouth sore. This is an acute infectious disease caused by aphthous virus. The disease is prone to occur in the lambing season, and there is no strict distinction between the onset ages (sheep mainly occur in lambs). It is often popular in groups, and both humans and animals can be infected. Sick sheep and animals carrying viruses are the sources of infection, mainly through damaged skin and mucous membranes. The disease can continue to harm sheep for many years, but the incidence rate in sheep is decreasing year by year. The incubation period of the disease is 36~48h, and the course of the disease is about 3 weeks. In the treatment of this disease, external treatment methods such as skin application or intramuscular injection can be used. In the treatment, you can choose one of the following two methods to achieve better therapeutic effect.
1 intramuscular injection
Prescription 1: Mix vitamin b 1 220mg with vitamin C 0.5g, then inject it into muscle twice a day, 1 course of treatment, for 3-4 days, for 2 consecutive courses of treatment.
Prescription 2: Sodium salt or penicillin potassium 4-5mg/kg body weight, Virulin 0. 1g/kg body weight, 1 time per day, 3 days for 1 course of treatment, continuous treatment for 2-3 courses, and the interval between courses should be 2-3 days.
Prescription 3: If sick sheep have systemic symptoms, intramuscular injection of Antongding 10 ml, sulfadiazine sodium 30 ml and Viruling mixture 20 ml every day for 3-5 days.
2 skin application and administration
The principle of treatment is to clean the mouth, diminish inflammation and converge. Self-made iodine glycerin, 30 ml anhydrous glycerin, 70 ml 7% iodine tincture, fully mixed and set aside. Gently remove the scab skin, then wash the affected area with 1% potassium permanganate, and then apply the prepared iodine glycerin to the affected area once a day 1 time for 7 days, with the treatment interval of 3 days.
Chinese medicine Kebingboron Powder (borneol 15g, borax 150g, mirabilite 18g, ground) is used twice a day, and new granulation tissue grows on the ulcer surface after 2-4 days.
Oral ulcer is a terrible disease, belonging to a lump, which is easy to occur in sheep aged 3 ~ 6 months. This is a * * * disease of people and animals, and its scientific name is "sheep infectious pustule". The disease spreads quickly. If a sheep is infected with this disease, the sheep will be infected soon. This is a kind of sheep oral virus, not common pathogenic microorganisms such as bacteria, mycoplasma and chlamydia. Big sheep rarely appear, but it is still very easy to treat in the early stage. If it is serious, it will die or become a stiff sheep.
Try not to feed hard grass when feeding grass. If there is hard grass, it must be picked out manually. Also, add some salt to the concentrated solution, and try not to let the sheep lick the wall and chew the soil to protect the skin and mucosa.
In areas where the disease is prevalent, it is necessary to inoculate attenuated vaccine against oral ulcer in sheep in time. In addition, thoroughly disinfect the sheepfold and the surrounding environment with quicklime, especially the maternity bed, sheep bed and trough!

Sheep aphthae is smeared with indigo naturalis powder, and then combined with heat-clearing and detoxicating injection.
Sheep aphthae, scientific name "sheep infectious pustule", is an infectious disease mainly caused by sheep aphthae virus, which can occur in both goats and sheep. Here are some methods and common methods for treating sheep's mouth sore.
The sick sheep first showed scattered little red dot in the mouth, upper lip or nasal mirror, and then developed into chickenpox or pustules. After the pustule ruptures, it will form a yellow or brown warty hard scab. If it is benign, the scab will gradually expand, thicken and dry, and fall off and return to normal within 1 ~ 2 weeks. In severe cases, papules, blisters, pustules and scabs continue to appear in the affected area, which merge with each other, affecting the whole lip, face, eyelids and auricle, forming a large-scale cracked and bleeding scab, often accompanied by granulation tissue proliferation, which makes the whole lip swell and turn into a mulberry-like protrusion, seriously affecting food intake, and the sick sheep gradually weaken and die. The course of disease lasts for 2 ~ 3 weeks. Some cases are accompanied by secondary infections such as pyogenic bacteria and necrotic bacteria, which cause deep tissue purulent necrosis and aggravate the condition.
Oral mucosa is often involved, forming pustules and ulcerations on the inner surfaces of lips, gums, cheeks, tongue and soft palate, accompanied by stench. A few cases will die of secondary pneumonia. The above pathological changes can also occur by infecting the nipple skin of sick sheep and ewe. Secondary infection can also spread to the throat, lungs and fourth stomach. The disease has no obvious seasonality and is more common in the spring and autumn lambing season. Because of the strong resistance of the virus, once infected, it is not easy to remove sheep, which can continue to harm sheep for many years, so we must find it in time and treat it in time.
The treatment of sheep's mouth sore should start from the root of sheep's mouth sore. Sheep's mouth sore is an infectious disease caused by virus, which is common in lambs aged from 3 months to 6 months in spring and autumn. Adult sheep can also be infected, but the incidence rate is less and it is sporadic. Treating sheep's mouth sore has always been a big problem that puzzles farmers.
1, the treatment of sheep aphtha is the ulcer on the tongue and mouth of sick sheep, which is washed repeatedly with clear water.
Wipe with 5% iodine glycerin or acetic acid; For scab, the scab skin of the affected area should be peeled off first, and then washed three times a day for 4-6 days. You can also rub it with gentian violet mixed with a little lime. The ulcer surface should be washed with 0.5% potassium permanganate or 10% saline or 3% hydrogen peroxide every day. Sick sheep with elevated body temperature can be intramuscular injected with antipyretics and antibiotics to prevent secondary infection.
2. If the hoof is diseased, soak the diseased hoof in 5- 10% formaldehyde solution for 3 times 1 min at intervals of 5-6 hours, and wipe the affected area with 3% gentian violet solution or oxytetracycline ointment the next day, which can effectively treat aphtha.
3. Common usage of treating sheep aphthae: Feed the affected sheep with Niuhuang Jiedu tablets, 2-3 tablets each time, twice a day; Or oral Chinese herbal medicines: Radix Sophorae Flavescentis, Radix Gentianae, Radix Cynanchi Paniculati, Fructus Zanthoxyli, Flos Huanghua and Radix Sanguisorbae, 65,438+00g each, decocted and taken warm three times a day for 65,438+0 weeks.
General drug treatment is ineffective or ineffective, and the resistance to conventional drugs is rapid, and the effect of long-term medication will not be obvious. It is suggested that Yangquan Qing (containing coated immunoglobulin, interferon, antiviral factor and freeze-dried powder of various traditional Chinese medicines for clearing away heat and toxic materials) should be used together with drugs for secondary infection, which can treat both the symptoms and root causes, with good effect and can effectively control the onset and secondary infection.
Well, I have been raising sheep for five years, but I have raised goats. I think sheep and goats are similar, and so are aphtha. Let me talk about my personal experience and practical experience and share it with you. A sheep that has been raised for five years will get aphthous after three years, especially lambs, which are prone to get aphthous, even in the ocean, but they will heal themselves without taking medicine. One year is when it is hot every day in summer, and the other two years are from cold winter to spring. Generally, lambs from seven days to the full moon are most likely to get this kind of aphtha. I feel that goat milk is not delicious in winter and spring hay season. Lambs lack vitamins, have low immunity and are prone to illness. Seventy or eighty sheep in my family are not very infected, and in order to keep warm, the air is closed and not circulating, so it is easy to get this aphtha. Aphtha is a virus infection, which is highly contagious. As long as one lamb is found to have this aphtha, other lambs will be easily infected together. Well, the last infection was after the Lantern Festival this spring. Infected 70 or 80 lambs, from half a month to one month old. Many cheeks are bulging, and they have rotted into the gums and throats, and their mouths are watering. This ice boron spray used by this person has a good effect. I bought a gram of ice boron powder with plastic. I can spray the powder of boron ice powder at the touch of a button. If I master it well and waste too much and too little, the effect will not be achieved. I feel it. Just touch the surface of this wound. Twice a day, a mild week is enough, and a serious week is needed. Many drugs have been used before, such as potassium permanganate, boron ice powder for animals and iodophor. I have also taken Niuhuang Jiedu tablets orally and injected ribavirin, but the effect is not ideal and the operation is troublesome. After practice, I feel that the ice boron powder used by this person is spray, and the effect is fast and good. As long as you pay attention, if there is too much rotten dirt on the wound surface, the concentration is 1%. Brush the rotten material on the wound to remove bleeding, and then spray the powder of ice boron powder. It is best to use them in combination, but you must master a certain degree. After brushing your teeth for three days, you can stop brushing potassium permanganate solution with your toothbrush, otherwise it will affect wound healing. You can keep asking me if you don't understand.
I am a farmer, too. My sheep has aphtha. I use it, oral spray for people, and iodine glycerin. Or sesame oil. Penicillin powder on the mouth
There is a pimple on the sheep's mouth, which may be sheep's mouth sore. Sheep aphthae, also known as "sheep infectious pustule", is an infectious disease caused by virus in sheep and goats.
First, the pathogenesis:
Sheep aphthae mostly occurs in spring and autumn, 3-6 months old sheep are susceptible to infection, and adult sheep can also be infected, but the incidence rate is less and sporadic. Natural infection is mainly caused by buying sick sheep or using polluted barns and grasslands.
Second, the symptoms:
1, Symptoms: The main symptom of sick sheep is oral and lip infection. At first, scattered little red dot appeared on the corners of the mouth, upper lip or nasal mirror, and then gradually turned into papules and nodules, and then formed small blisters or pustules, which spread to the whole mouth, lips, face, eyelids and auricles, forming a large area of cracked and bleeding dirty scab, and granulation tissue under the scab proliferated, and swollen lips became mulberry-like protrusions. The oral mucosa is often damaged, and the mucosa is flushed, and blisters appear on the inner surface of the mucosa of lips, gums, cheeks, tongue and soft palate, and then pustules and rotten spots appear. If it is accompanied by secondary pollution such as necrotic bacteria, it will deteriorate into a large area ulcer, deep tissue necrosis and bad breath. Sick sheep do not want to eat because of pain, which is characterized by salivation, listlessness, loss of appetite or abandonment, decreased rumination, rough and dull fur and thinning. Mammals who nurse ewes may also get sick, mainly because they are bitten by lambs.
What medicine is good for sheep's mouth sore, what medicine is good for sheep's mouth sore, and it is not good for sheep's mouth sore.
Third, the treatment plan;
Cattle and sheep pox sore kang+all diseases pioneer intramuscular injection is effective, 3 days treatment!
In addition, combined with oral and hoof quick treatment spray, it can quickly reduce swelling and relieve pain! Take effect in 2-4 hours and quickly scab!
Fourth, how to prevent sheep from getting sick at ordinary times
There are several key points in raising sheep:
1, the management of the sheepfold, just two words clean. It can't be hot in summer and cold in winter.
2, the management of feeding, we must know the ingredients, can not eat more, can not eat less. . More indigestion, less is not long. .
3, a very important point: the prevention of diseases, what season to prevent what diseases, vaccination or drugs in advance. .
4. Important point: It will cure some common sheep diseases. 1, acute flatulence 2, diarrhea 3, cold 4, myopathy, this thing is terrible and difficult to treat 5, parasitic disease 6, dermatosis 7, aphtha 8, and sheep pox. Generally speaking, these are common. If we can handle the above problems, it will not be difficult to raise sheep.
Sheep aphtha, also known as sheep infectious pus scar, is first isolated from the sick sheep and thoroughly disinfected the pens and sports grounds. Feed the sick sheep with soft, digestible and delicious feed to ensure sufficient clean drinking water. Remove the scab from the affected area, wash the wound with light salt water, and apply purple liquid to the wound twice in 1 day until it is healed. If you have a fever, you can inject goat serum immune peptide and high content of ceftiofur sodium at the same time 2 13 days after Bupleurum has cooled down. For reference only, take care of it. It's okay.
