Diseases of sheep can lead to death, and in the most severe cases, a rapid infection of the entire herd occurs. Prevention will help prevent negative consequences and protect animals. To do this, you need to know from what diseases the sheep can suffer, what symptoms are accompanied and how to conduct effective treatment?
Sheep non-communicable diseases
This category of diseases does not carry a great danger. The main thing is to start treatment in a timely manner and not to forget about the importance of preventive measures.
Stalling in the animal’s stomach, plant fibers and their own hair is called an ovarian disease. Most often, young individuals suffer from this ailment, which remain hungry due to a lack of milk from the mother. Due to the lack of minerals with vitamins in the diet, the animal begins to eat its own wool, trying in this way to make up for the lack of useful elements.
A sheepless stomach stone
A sick animal behaves uneasily, suffers from poor appetite, begins to examine other animals, trying to eat their coat. Such symptoms also appear - blue mucosa, the sheep tries to constantly defecate.
There are no effective preventative methods. To prevent the formation of bezoar stone in the stomach, make a complete and proper diet, saturated with essential minerals and vitamins.
Digestive problems are noncommunicable diseases. All animals can suffer from the disease, regardless of age and gender.
The disease is accompanied by poor appetite, a sense of anxiety, severe bloating occurs. Poor nutrition affects both adult animals and lambs. The disease can lead to the fact that one of the gastric scars ceases to function.
Bloating sheep on the right
For treatment, a special tube is inserted into the mouth of a sick animal to restore the full functioning of the scar. In this way, accumulated gases are removed. Such actions do not always bring results. In the most difficult cases, a scar puncture is required.
In the case of the formation of a purulent infection of the udder, as well as damage to the kidneys with the uterus or other organs located close by, inflammation of the mucous membrane of the bladder occurs. The sheep feels the need for constant urination, in which severe pain is disturbing.
With the development of the disease, body temperature rises, it becomes impossible to urinate, and humping appears.
During treatment, the sheep are transferred to light feeds, and plenty of drinking is given. The animal is given hydrochloric salt with benzoic acid. In some cases, bladder washing is performed using various solutions. Intramuscular injections with the use of sulfonamides with antibiotics are given.
This is a common problem that many sheep owners face. Poisonous plants eaten by a sheep can provoke poisoning. The problem manifests itself with severe vomiting, impaired stool, refusal to feed, high fever.
The greatest danger of poisoning is for lambs, a young body can not tolerate a serious condition. The most effective is the immediate gastric lavage using sunflower oil (110 ml) and a special salt solution (60 g of salt is taken for 550 ml of water).
There is inflammation of the skin of the animal. Individuals are allergic to various irritants - chemical, mechanical, or fungal ( Pithomyces chartarum ). There is a likelihood of developing eczema as a result of improper and limited nutrition, inappropriate conditions of detention, as well as in the presence of various diseases that have a chronic nature of the course.
With eczema, papules, redness appear on the skin of the animal, the growth of vesicles and pustules begins, the skin is covered with scabs, depletion occurs. The treatment is based on the immediate elimination of an existing stimulus. Medications are prescribed to maintain the liver. Also, the sheep should be transferred to another food (hypoallergenic and safe, since grass poisonous to the sheep can grow in the pasture), take a vitamin course (but do not exceed the dosage, otherwise the sheep will have toxic liver damage), and not to graze in direct sunlight ( provide shadow).
With this disease, inflammation of the bronchial mucosa occurs, and the lungs are affected. A sick animal has a high temperature, lack of appetite, rapid breathing, coughing, mucus that has an unpleasant odor is released from the nose.
Treatment is carried out with the help of sulfonamides. The administration of gamma globulin, as well as antibiotics, is prescribed. Drugs that stimulate the proper functioning of the heart can also be prescribed.
Be sure a sick animal is assigned a special diet.
With stomatitis, inflammation of the oral cavity occurs. This condition can be triggered by mechanical damage, chemical or thermal effects, including the action of certain biological factors.
It is difficult for a sick animal to chew food, since erosion forms in the oral cavity, the tongue can be coated with white coating. Abundant salivation begins, the animal champs ceaselessly.
For treatment, sheep are transferred to liquid feeds that have a mucous or acidic consistency. You can give and talkers. Regularly treat the erosive areas of the oral cavity with hydrogen peroxide.
Given the form of the disease, various symptoms may appear:
- catarrhal - the eyes can be closed or half-closed, the fear of light develops, severe tearing begins, the conjunctiva swells and reddens;
- purulent - the discharge of purulent contents begins, the edges of the eyelids become covered with ulcers;
- phlegmonous - the conjunctiva protrudes, swelling of the mucous membrane of the eye develops;
- follicular - inflammation of the follicles occurs from the inside of the third century.
Regularly cleanse the mucous membrane of the eye from purulent discharge. For this, an aqueous solution of boric acid, corticosteroid and antibiotic ointments are used. To prevent the follicular form, cauterization is performed using a lapis pencil.
It is an inflammatory disease affecting the joints. As a result, this leads to deformation of their shape. A sick sheep is very lame, suffers from pain, swelling appears and the temperature rises. The sheep refuses to move, loses coordination.
Add as much alfalfa as possible to the sick animal in the diet, as it is very nutritious and helps to reduce the amount of concentrated feed. Take massage courses for the affected joint. It is also regularly lubricated with ointments that have an irritating effect.
With this ailment, damage to the muscles of the animal’s body occurs. Compaction of the diseased muscle begins, the sheep is worried about soreness, the skin swells in the affected area. The animal is very lame if a limb muscle injury has occurred.
During treatment, a warming compress is applied to the affected area, physiotherapy is performed. If an abscess forms, it is opened, sulfonamides with antibiotics are administered intramuscularly.
Hoof rot is one of the most unpleasant diseases that leads to severe inflammation - hoof pulpitis. The disease is accompanied by lameness, the animal becomes difficult to move. For treatment, trimming of the hoof is performed.
Tendonitis or inflammation of the tendons becomes the result of trauma and infection of the sheep. The sheep is severely limping, pain, disturbed area, swollen area, swelling, fever.
A cold dressing is applied to the inflamed area, which will exert pressure. To remove the resulting exudate from the bags of inflammation, a small puncture is made. After thorough cleansing, all cavities are treated with special antiseptic agents.
Gradually, a decrease in the amount of exudate occurs. Over time, you can begin to massage using camphor oil.
White Lambs Muscle Disease
For lambs that were born a few days ago, this disease is the most dangerous, it can not be treated. In about 65%, the animal dies. The onset of dystrophic processes occurs due to the development of vitamin deficiency.
The sick lamb begins to limp, cramps, swelling and weakness appear, breathing quickens. But you can prevent the onset of the development of the disease. To this end, vitamin E and other valuable minerals, primarily selenium, are introduced into the diet of an adult animal. Give pregnant sheep regular minerals.
Violation of the integrity of the bone is called a fracture, which can be closed or open. In the first case, only the bone is damaged, in the latter, the skin is also broken.
If the animal has a fracture, a swelling appears in the area of the injury, the limb is deformed, the animal is worried about severe pain. In case of damage to the humerus, tibia and femur, culling of sheep is carried out.
For treatment, a retaining dressing is applied to the damaged area, and complete rest is required. The limb and dressing is fixed in a fixed position. Use solid objects for this.
If tissue is damaged during the fracture, the wound is treated with clean water and using antiseptics. It is required to use a fixing bandage, gypsum does not fit. Periodically, fluid may be released from the wound. It is important to regularly remove it, and the rupture site is disinfected, as there is a risk of a septic phenomenon.
A sick sheep is supplemented with vitamins and mineral supplements, and loads are regulated. The benefit is massage of an injured limb.
Sheep Infectious Diseases
When diagnosing an infectious disease, a sick sheep is immediately isolated from the herd. If the necessary measures are not taken in a timely manner, there is a risk of infection of the entire livestock.
This is a contagious and serious illness during which the central nervous system suffers. Infection leads to the death of a sheep. There is a high risk of infection of other members of the herd. At risk is a person. The causative agent is a virus that is unstable to elevated temperatures, acidic as well as alkaline types of disinfectants.
With a quiet form of the disease, the sheep begin to moo hoarsely, salivation increases, gait swaying and uncertain. The sheep refuses food and paralysis develops.
With a violent form of the disease, the sheep begins to behave very aggressively, tries to break off the leash, starts to roar and beat against the wall for no reason, can dig a lot of holes in the ground.
As a prophylaxis, vaccination of sheep against rabies is carried out. The farm is protected from stray dogs and other animals that may be potential sources of infection.
To date, there is no effective treatment that will help get rid of rabies. When diagnosing a disease, a sick animal is removed from the herd, isolated, then slaughtered.
An acute infectious disease, which is accompanied by high rates of intoxication, as well as inflammatory processes occurring in the abomasum (part of the stomach). Not all sheep can become infected, but all infected individuals die.
The disease is excited by a rod-shaped microorganism, which infects the animal and produces a dangerous toxin inside it. The stick has a high sensitivity to various disinfectants.
The disease is characterized by a rapid course. The animal begins severe cramps, the gait is shaky, is in agony. The animal dies in a couple of hours.
To date, there is no effective treatment for this disease. In the form of prophylaxis, vaccination is recommended in a timely manner.
This is a contagious disease that can be transmitted to humans. There is inflammation and further damage to various parts of the animal’s body. The causative agent is Brucella bacteria ( Brucella ), which are not resistant to high temperatures and various types of disinfectants.
The disease proceeds without symptoms and may remain invisible. You can determine the presence of the disease by delay in the afterbirth, the testicles become inflamed in the ram, and the pregnant uterus has a spontaneous abortion.
In the case of the development of a severe form of the disease, hind limb paralysis occurs in the animal.
Treatment does not give a result and is ineffective, so a sick animal is sent for slaughter. In the form of prophylaxis, before introducing a new animal into the herd, it is tested in a veterinary clinic to determine the presence of brucellosis.
An infectious disease in which epithelial cells grow on the respiratory tract. It can be manifested by a strong cough, discharge from the nose is observed. It is extremely rare that the disease proceeds without visible signs.
It is almost impossible to cure an infected animal. The sheep is immediately removed from the herd so that the remaining animals do not become infected.
A serious illness that can lead to the death of a whole herd. The animal organism is affected by bacterial microorganisms. Different forms of the disease are distinguished - with nervous listeriosis, in 100% of cases the death of the animal occurs, since there is no treatment.
The ailment is accompanied by apathy, appetite is completely absent, convulsions, paralysis, disturbances of the musculoskeletal system appear. If there is such an opportunity, it is worth immediately taking sheep that are immune to the disease.
The characteristic behavior of a sick sheep
The disease manifests itself with acute inflammation of the udder: it hardens, redness and swelling may occur, and the process of feeding the lamb, milking or pumping causes pain. With a severe form of the disease, a significant increase in temperature and the release of pus from the nipples occurs. The development of the disease occurs when a bacterial infection enters the udder through damaged nipples due to the content of sheep in adverse conditions.
Antibiotics are used for treatment, with repeated inflammation, an udder is cut out. Effective prevention is the proper care of the sheep, compliance with all hygiene rules, timely milk production and applying the lamb to the udder.
Often there is a development of the disease simultaneously with infectious mastitis. The first signs appear after or during childbirth in the female.
The disease is accompanied by soreness and pronounced redness of the udder, conjunctivitis, milk changes color, appetite disappears, arthritis develops.
Treatment of the disease is possible only with the use of antibiotics. If the sheep has weak immunity, there is a risk of death.
This is a very common disease that can lead to serious consequences. Lambs and adults suffer. Weakened animals die.
This disease manifests itself with an increase in body temperature, partial loss of hair with the formation of papular-pustular rashes, severe salivation, nasal discharge. A sick sheep completely refuses food.
An infected sheep is immediately isolated from other animals to prevent the spread of infection. Antibiotic treatment may be prescribed. In the absence of progress, a sick animal is killed, corpses are burned, as the disease is highly contagious.
Effective prevention - timely vaccination.
An infectious disease that often affects herds of sheep. The main indicator is the presence in the blood of an animal of pathogenic organisms - Pasteurella multocida .
The disease is dangerous and can be transmitted to humans.
The course of the disease is accompanied by an instant rise in temperature, the onset of severe diarrhea, an oppressed state of the sheep is observed. Severe edema appears, swollen legs with joints. Anemia develops.
The disease is treated by injection using hyperimmune serum, sulfonamides with tetracycline are prescribed.
Effective prevention is timely vaccination, strengthening the immunity of animals. If an infected sheep has been detected, it is immediately isolated from the herd, and the premises are treated using disinfectants.
Salmonella is a pathogen that has a high level of resistance to various disinfection drugs. Lambs often suffer from this disease. In about 50% of cases, death occurs.
The disease manifests itself with an increase in body temperature (fever) and the presence of diarrhea (possibly with blood), a sick animal refuses to eat. Sheep becomes breathing hard. If the lamb has not died on the 6th day, then it begins a constant cough (pneumonia develops), joints become inflamed. He can live up to 10 days.
A sick animal is isolated to prevent the spread of the disease. Treatment is with antibiotics (e.g. synthomycin). Nitrofuran agents (for example, furazolidone) and sulfonamides (norsulfazole, etc.) are also used.
The disease is very contagious, characterized by a rapid course. Not only animals are at risk of infection, but also humans. When infected, swelling with ulcers appears on the body of the sheep. Carbuncle can appear on the skin and internal organs.
Microbial bacillus provokes the disease, it is difficult to completely destroy it. Infection of sheep can occur while eating infected food.
Given the nature and development of the disease, various symptoms may appear. A strong and incessant tremor is observed, the body temperature rises, the mucous membrane of the eye turns blue, the lymph nodes under the jaw are hot, swelling of the lower jaw develops.
For treatment, a specific serum is used, introduced into the muscles - 10 ml per animal. Gamma globulin injections are also used. Antibiotics related to the penicillin series are intramuscularly administered.
This is a dangerous disease affecting the nervous system. It becomes the result of infection with various microbes. The disease is seasonal, most often the sheep suffer from it in the spring season. The disease goes through several stages - it begins with a chronic one, flows into the subacute, then acute and super acute.
The disease manifests with shortness of breath, mucus is liberated abundantly from the nose, salivation increases, and problems associated with the condition and functioning of the gastrointestinal tract appear. The treatment will be effective during the subacute stage, when antibiotics are prescribed.
Foot and mouth disease
The disease is characterized by a rapid spread. Aphthae, erosion in the gap between the hooves, including on the mucous membrane of the mouth, appear on the body of the infected animal. There is a risk of human infection. It provokes a disease - a virus from the picornavirus family. It has high resistance to various factors.
In 100% of cases, death of young animals occurs. When infected with adult animals, death occurs in approximately 40-85% of cases.
Sick animals become sources of the spread of infection. The sick sheep has a high temperature, rashes appear in the mouth and around it that look like bubbles filled with a cloudy liquid. Aphthae also affects the inter-experimental gap. The duration of the disease is not more than 30 days.
Provided that treatment is started correctly and on time, the animal recovers completely without serious negative consequences. Antibiotics are administered by injection, cardiac drugs may be prescribed. When hooves are affected, baths with formalin solution are made.
Sheep parasitic diseases
It is parasitic diseases that are the most common type. Infection can occur through contact with a sick animal or as a result of adverse conditions.
In the gallbladders, parasitism of flatworms of the Fasciola genus begins. Damage due to the use of contaminated water or food is possible. The disease can last for many years.
An ailment is manifested by hair loss, diarrhea or constipation develops, a high temperature is observed. The animal’s appetite is almost completely lost, severe exhaustion and weakness develop.
Treatment is carried out using anthelmintics prescribed by a veterinarian. De-worming is performed at least twice a year.
An invasive form of the disease, which is spread by parasites dicrocels, settling in the liver and gall bladder. Parasites can live inside the body for several years, and the disease does not show any signs.
For treatment and prevention, anthelmintic drugs are used, which are mixed in food. The territory where sheep graze is being checked.
Sheep dicroceliosis development cycle
Larvae of cestodes infect internal organs. At first, the disease does not manifest itself, but diarrhea soon begins, appetite disappears, and sudden weight loss and exhaustion are observed.
To date, effective methods of treating the disease are not known. Prevention is to limit the contact of sheep with stray dogs.
This is a parasitic disease provoked by ostertagias that have settled in the abomasum. Weakness is observed in a sick sheep, weight loss occurs, submandibular areas swell, thirst begins.
Treatment is carried out with the use of anthelmintic agents, which are mixed with food. To eliminate parasites, such drugs as fentosian, nilverma, naphthamone can be introduced. These same tools are also prevention.
This is a parasitic type of disease caused by a cestode that settles in the small intestine. Within 3 months, development from an egg to a fully matured worm occurs. In length, while inside the animal, it can reach 5 m. Ticks act as intermediate carriers of parasites.
When infected, the animal refuses food, diarrhea, colic begins, during the bowel movement the back flexes greatly. The coordination of movements is disturbed, the animal begins to press its head to the stomach or falls on the stomach, trying to reduce pain.
Effective prevention is deworming. It is performed in 4 doses, it is advisable to carry out under the supervision of a veterinarian.
Disease transmitted by ixodid ticks. There is fever, fever, and general weakness. After the virus invades the brain, the signs of the disease soon disappear, but the temperature rises again. The functioning of the nervous system is disrupted.
If within a few days, after infection, the animal does not die, there is a chance for an independent recovery.
The disease is provoked by a pyroplasm parasite that infects internal organs and blood. For treatment, the course of taking antibiotics is prescribed.
The disease appears yellowing of the mucous membrane, severe diarrhea, lack of appetite. The animal refuses even water. In the urine there is a red tint, breathing quickens, the temperature rises. The animal looks tired and lethargic.
Yellowing of the oral mucosa due to liver damage
Thelerites parasites provoke the disease. Sick animals that have been infected by ticks become sources of the spread of infection.
An ailment is manifested by enlarged lymph nodes, high temperature, the proper functioning of the cardiovascular system from the digestive system is disrupted. For prevention, treatment of pastures from ticks is carried out.
A 7% azidine solution will help get rid of parasites. The veterinarian may prescribe the use of other drugs. Drugs should be used in a comprehensive manner, but no more than each remedy three times.
Ticks of a saracoptoid species that have settled on the skin of sheep cause scabies. Damaging the integrity of the skin, ticks feed on lymph and fluid. Sick animals become the source of the spread of the disease.
The disease manifests itself with severe itching, hair loss occurs, irritated skin thickens. The temperature rises, in the habitat of ticks appear bubbles and painful crusts.
To kill ticks, the animal needs to be washed using activated creolin or hexalin. Butox or ivomec injections may be prescribed.
For prevention, the sheep are quarantined, be sure to carry out treatment against ticks.
Wingless flies infect sheep, which multiply rapidly, lay eggs in the animal’s hair. Therefore, there is a risk of instant damage to the entire livestock. Both adult sheep and young animals are affected.
The disease is manifested by the tearing of the sheep’s hair. Strong exhaustion and diarrhea begin, the amount of milk decreases. Treatment should be prescribed only by a veterinarian. If a sick individual is found, it is urgently isolated.
The disease is provoked by parasites - strongils living in the mucosa of the small intestine of the host. But infection occurs through the entry of larvae into the wound. After penetration into the body, larvae with blood enter the lungs, provoking their irritation. Together with sputum, they are separated, then animals swallow it, after which the larvae find themselves in the intestinal tract, where they develop.
After infection, the young lambs die.
The disease manifests itself with severe coughing, itching in the area where parasites penetrated the body. The sheep begins to behave uneasily, pleurisy or pneumonia develops, weight is rapidly lost. The animal refuses food, an oppressed state is observed.
Anthelmintic drugs (for example, thiabendazole or fenbendazole 0.01 g / kg once) are used during treatment to remove worms from the body of the animal. Prevention is the periodic cleaning of the stall, which should be carried out every day. In the first 60 days after birth, the lambs are regularly examined for parasites.
This is a dangerous disease that affects the brain of a sheep. Almost always after infection, the death of the animal occurs.
The disease manifests itself in aggression or shyness of a sheep, convulsions. Coordination is disturbed, inhibition appears and reflexes are absent. A sick animal often begins to throw its head back.
Sheep can suffer from a wide variety of diseases. Some pass without special problems, but there are those that can lead to the extinction of the entire livestock. The timely vaccination and care of the sheep will help maintain the livestock and prevent the onset of the epidemic.
