Eating eggs can transmit diseases from the chicken

Poultry diseases - description and their treatment

Bacteria. Very contagious and often spreads like an epidemic.
Small pus and ulcer nodules on the internal organs, especially in the liver and intestines. Sick animals sit around lonely. Combs and wattles turn pale, the animals become light, the laying activity ceases, the plumage is shaggy, and the chickens get diarrhea.
With the help of the tuberculin test, which is carried out by the veterinarian, suspicious animals can be recognized. These must be slaughtered immediately. If the infestation is severe, the entire stock should be slaughtered. Then thoroughly disinfect the stable and the equipment.
Usually breaks out in autumn or winter and is favored by drafty stalls and a lack of vitamin A.
Sneezing, gasping, nasal discharge, and inflammation of the eyes
The infected animals are to be separated. A disinfectant must be added to the drinking water. The animals can also be treated by rinsing their noses with hydrogen peroxide or with 5% warm boron solution, then instilling camphor oil two or three times a day. Inflamed eyes are washed with boron water. Stable and equipment disinfection.
When the outer skin is affected, it is called smallpox, when the mucous membranes are affected, it is called diphtheria.
Easily transferable and is mostly brought in by strange animals. The disease can easily be mistaken for a runny nose. However, a yellowish coating forms on the mucous membrane of the beak, throat and trachea.
If the animals have not yet lost weight, they can still be treated. The affected mucous membrane must immediately be brushed daily with iodine glycerine until it has healed. Sulfloliquid is to be added to the drinking water. Stable disinfection must be carried out carefully. Preventive vaccinations can be given against smallpox diphtheria. The vaccination is effective for a year.
Viral infection of the respiratory tract, extremely contagious and acute. Mainly affects young animals between 10 and 21 days old. The pathogen can be transmitted through contact, with the help of droplets from the respiratory tract of sick animals and through intermediate carriers. The incubation time can be 18 to 36 hours, for chicks up to 6 days.
The chicks show shortness of breath (beak breathing), nasal and eye discharge, rattling noises, wheezing, coughing and sneezing, fatigue and a pronounced need for warmth. Occasionally, swelling around the eyes is observed. The sick animals lag behind in growth. In laying hens, the laying performance drops very quickly and sharply within a very short time, in some cases defaced, thin-shelled eggs with a rough surface are laid.
Losses can be very high in chicks as young as a few weeks old. A reliable diagnosis is possible via the pathogen detection. Vaccinations are possible, but they do not always have the desired effect. Good hygienic conditions are advantageous. As a preventive measure, the chicks of different age groups should be purchased from demonstrably healthy stocks and well isolated.
Atypical avian influenza (Newcastle disease)
Viral disease, highly contagious and spreading quickly. Is transmitted by sick animals through discharge from the nose and beak, through feces, eggs and feathers. Ducks, geese, pigeons, parrots and numerous wild birds can also become ill.
After an incubation period of 4 to 5 days, after reduced appetite and fever, drowsiness and partial indolence appear. The comb and wattles turn blue. The animals sit with ruffled plumage in dark corners, keep their eyes closed, show discharge from the beak, nose and eyes, head shaking, shortness of breath, make strange wheezing sounds and can show greenish diarrhea and paralysis. Pinhead-sized bleeding in the glandular stomach and other organs, as well as ulcers in the intestine, are highly suspect for this disease.
A reliable diagnosis is possible with virus detection and serological methods. The illness is notifiable, a vaccination is possible and the control measures are carried out according to the official veterinarian's instructions.
The bacteria are mainly transmitted through body excretions.
The animals do not eat, but ingest a lot of water and have diarrhea, some of which is bloody. The face, crest and wattles are dark to bluish red.
Poultry cholera is notifiable.
The herd should be slaughtered immediately and burned in the animal incinerator. Stable and equipment must be thoroughly disinfected immediately and entry to the homestead is prohibited for strangers.
The pathogen is a virus and can even be infectious in cold store poultry for up to 12 months and is very easily transmitted.
The disease manifests itself through indifference, bluish-red discoloration of the crest and wattles, conjunctivitis, reddish-gray mucus in the beak, diarrhea, swelling of the head and neck, rattle, paralysis of the limbs. Death occurs after 2 to 5 days.
Avian influenza is notifiable.
Vaccination is highly recommended.
In the event of an outbreak of the disease, the entire herd must be killed and the stable and equipment must be thoroughly disinfected.
In addition, a homestead lock will be ordered.
Salmonellosis /
White chick riot
Caused by different types of Salmonella bacteria. Liver, spleen and kidney damage as well as inflammation in the gastrointestinal tract and joints occur.
Chicks suffer from severe general disorders in the first few weeks of life and initially give off a watery, greenish, then whitish, chalk-like feces. Joint inflammation can be observed in older chicks, or the disease passes through a creeping stage of disease without serious symptoms due to factors that reduce the force of resistance when they are ready to lay into an acute stage.
With serological methods, depending on the stage of the disease, the infection can be reliably determined in living animals. Drug treatment lowers the mortality rate. However, since the animals remain bacterial excretors, the stocks can only become free of pullorum by adhering to strict hygienic measures and by eliminating infected animals.
The pathogen is a parasite that lives in the cells of the intestinal wall. The pathogen is transmitted through the faeces. The risk of infection is particularly high when the chicks come together with older chickens (cluck), as these can excrete coccidia without being sick themselves.
Sick animals sit around a lot, are not very lively, let their wings hang down and empty a thin, bloody excrement.
Treatment is possible by cleaning the stable every day. Ask the veterinarian about disinfectants and other treatments. In order to prevent diseases, a strict separation between old and young chickens is necessary.
Mites, feather lice and lice
Most common skin parasites in poultry. Only the red mite causes sudden deaths.
They lead to limestone bones, loss of feathers and, as a result of the itching that they trigger, reduced performance.
All of these skin parasites can be effectively combated by dusting the infected animals and disinfecting the stables.
Infectious inflammation of the larynx and trachea
Very contagious viral disease of chickens and pheasants. The larynx and windpipe develop severe inflammation.
After an incubation period of 4 to 12 days, ocular and nasal discharge occur. With coughing and shaking the head, bloody mucus emerges from the beak, causing shortness of breath and finally suffocation of the animals. If the animals survived the disease, they can excrete the pathogen for up to 16 months afterwards.
Effective treatment is not possible. Vaccinations can prevent. Sick animals should be slaughtered as quickly as possible and animals should only be kept in the thoroughly cleaned and disinfected stable after 2 months.
Very rapid distribution in ducklings between 3 and 20 days old. Here the mortality rate can be up to 95%. From the 5th week the ducklings are no longer susceptible. The pathogen can be transmitted via the egg, the food or the air.
The illness often lasts only several hours, usually less than a day. The chicks do not eat food, are drowsy and sleepy, lie on their side and show uncoordinated movements of their head and legs. Shortly before death, the head and neck are bent towards the back (opisthotonus) and both legs are stretched backwards. Dead animals have clay-yellow, swollen, and bleeding livers.
Special virological examinations secure the diagnosis. Passive and active vaccinations can be used as a preventive measure as a treatment is not known.
Highly infectious viral disease in ducks, goose and swans.
After an incubation period of 5 to 12 days, severe disorders of the general condition (refusal to feed, fluffy plumage, fatigue), diarrhea, swelling and reddening of the mucous membranes of the head, lacrimation, shortness of breath and blue-discolored beak are found. Sudden deaths, mostly in well-fed, adult animals, are also possible. Slimy, yellowish, stubborn deposits on the esophagus and intestinal mucosa and extensive punctiform and splatter-like bleeding on the heart and lining of the body cavity can be found in dead animals.
The virus is transmitted through intermediate carriers and contact. Wild ducks can be involved in proliferation over greater distances. A reliable diagnosis is possible with the help of special serological tests and virus cultures. Preventive vaccinations can be done.
Viral disease in four forms (nerve, eye, mixed and intestinal form). It is excreted with skin or feather particles, but also with saliva and nasal secretions and is infectious for a year in stable dust. Most illnesses and deaths occur between the 30th and 180th day of life, after which the animals are hardly infected.
With the nerve shape, leg weakness, staggering, parade-march-like gait, paralysis, change in the position of the toes, but also a split position of the legs and slack hanging of a wing are determined. The eye shape is more common in animals over 9 months old. The iris has an overgrown gray-green to gray-bluish hue and the deformed, narrowed, slit-shaped and fringed pupil no longer reacts to the effects of light. In the form of the viscera, tumor-like gray-white nodules are found in the organs.
A microscopic examination of the changed organs confirms the diagnosis. Treatment of sick animals is not possible. Preventive vaccinations on the first day of life can be carried out.
Infectious disease caused by bacteria and proven in over 100 species of birds. The disease can be transmitted to humans as a zoonosis.
The infection occurs through the mucous membranes of the head and by inhaling the pathogen. The incubation period is 7 to 14 days, after which fatigue, drowsiness, loss of appetite, runny nose and conjunctivitis appear. The infection is often barely noticeable and develops into a serious illness if there is an additional weakening of the resistance through additional infections and parasite infestation.
Treatment can be with antibiotics (chloramphenicol, tetracyclines). Flu-like illnesses and pneumonia have been observed in humans.
Slow disease. It occurs mainly in cocks after the 4th week of life and in laying hens 4 to 8 weeks after the start of the laying activity. Infection occurs directly from animal to animal, via the hatching egg or through intermediate carriers. Clinical symptoms of the disease often only appear after the animals have been exposed to stress (transport, relocation, malnutrition, unsanitary conditions, wormer cures, vaccinations), although an infection may have existed for a long time.
A runny nose and discharge from the eyes and nose develop, as well as sneezing, and the head may swell. The disease can be complicated by other pathogens, e.g. colic germs. Sinusitis in turkeys can be caused by Mycoplasma gallisepticum or M. meleagridis. This leads to a noticeable inflammation of the lower eye sockets, which leads to a strong increase in the circumference of these head parts and thus to the formation of an owl's head. The lower eye sockets are then filled with stinking, viscous to crumbly masses. The infectious joint inflammation of the chicken is caused by M. synoviae and occurs in all age groups. After an incubation period of between 24 to 80 days, the animals are beaten, show pale combs and are lame. Joint cavities and bursae swell and contain a watery, fluffy fluid.
Mycoplasmosis can be reliably detected using serological methods and pathogen detection. Certain antibiotics can be used for treatment.
As a result of metabolic disorders, e.g. if there is insufficient exercise, too dense stocking and boredom, feather pecking and finally feather eating occur.
If there is a lack of animal protein, this can degenerate into "cannibalism". Other symptoms are toe pecking, pecking of the anus, comb, pecking at feces and egg eating.
The run should be improved and distraction should be provided by scattering dry fodder, lime, chalk, bone meal, green fodder and beets. Red emitters / dark emitters have proven themselves in chick rearing.
Is caused by foreign bodies, rotting fodder or spoiled drinking water or by overfilling the crop with dry fodder, potato peels, beet pieces, matting due to dry grass or parasite infestation.
Clearly protruding goiter, difficult swallowing and bad smell from the beak.
If massage in the direction of the head does not help, the vet should do a goiter rinse or goiter cut.
Red tracheal worms, 0.2 to 3 cm long or white bronchial worms, 0.4 to 3 cm long. Intermediate hosts are earthworms and snails.
Coughing, throwing the head, gasping for air, shortness of breath, snoring and emaciation. Very high mortality.
To make the worms visible, one holds the neck of the animal against a strong light source. Because of the difficulty of treatment, veterinary assistance is recommended. The stable is to be disinfected. Healthy animals are to be segregated and a new area has to be created for young animals.
This disease is caused by different types of mites.
The limestone mite spreads slowly and causes gray-white scales on the legs, later thick, gray chunks (limestone legs). The legs are misshapen and thickened as if covered with mortar. Itching and death through emaciation are consequences of the infestation. The mite of the body mange causes flaking, loss and breakage of feathers, especially on the back, stomach, neck and head. The skin is reddened. Furthermore, nodules, emaciation and moulting disorders can be observed.
Foot mange is combated by immersing the legs in 5 to 10% creoline solution (5 minutes) several times at 3 to 6 day intervals. To combat body cramps, a sulfur liver bath (2%) is used for 3 minutes. Then the animals are dried in a warm room, the stable and equipment must be disinfected with contact insecticides (powder).
Caused by tapeworms, roundworms, roundworms, hairworms or tracheal worms, intermediate hosts such as beetles, flies, ants, snails and earthworms play a role in the transmission of some of the numerous parasites.
If sexually mature parasites have developed in the animal, the diagnosis can be made by detecting the sex products in the faeces.
In order to combat the parasite invasion, it is necessary to determine the type of parasite in order to be able to use the corresponding effective drugs. Hygienic measures must support the therapy.
These are uric acid deposits in joints and internal organs due to overfeeding of protein, feeding of moldy corn and lack of exercise.
These deposits cause joint swelling, lameness, joint stiffness, emaciation and weakness.
Allow diet and exercise, veterinary treatment if necessary.
Inflammation of the fallopian tube, careless grasping by the nursing staff, broken, shell-less eggs or eggs that are too large and got stuck in the ovary.
Reluctance to eat, drooping of the wings, clenching and convulsions
The condition can usually be remedied by rinsing with warm disinfectant solution (1/2 to 1%), then running in with oil and removing the egg with a careful massage. If necessary, the veterinarian has to pierce and destroy the egg.
By ingesting grain that is infected with ergot fungus.
Symptoms of poisoning occur, with death of the foot ends.
The damage can no longer be repaired.
Due to infection with swine rot bacteria
Disturbed general condition, fever, diarrhea and death in 1 to 2 days or longer infirmity.
Vet vaccination is recommended.
Vitamin A deficiency
Incorrect feed composition and permanent housing (chicks).
White coating on the third eyelid, conjunctivitis, nasal discharge, yellow-white coating on the base of the tongue, hard palate and in the larynx, clouding of the eyes, restlessness, nervousness, peculiar postures, addiction to sleep, cramps.
Green fodder, carrot mash, cod liver oil.
Vitamin B deficiency
Incorrect feed composition and permanent housing (chicks).
Unsteady gait, buckling, falling over, emaciation, paralysis, diarrhea.
Vitamin B deficiency
Incorrect feed composition and permanent housing (chicks).
Rickets (soft bone), swelling of the joints, weak legs in the chicks (often in artificial brood), thin and soft-shelled eggs.
