A novice farmer will not rejoice at small yellow lumps that chirp merrily, sort out in a matter of seconds the food brought by him, and grow with lightning speed.
All would be nothing, but dangerous viruses are not asleep and waiting for their victims. One of the most dangerous diseases of birds is the pseudo-snake, which in a few days can destroy all poultry in the farmer’s farmstead.
What is pseudotum in chickens?
The disease is characterized by damage to the nervous system, digestive organs and the breathing of chickens. It kills birds of different ages: from chicks to adults.
The organisms of other birds, such as peacocks, turkeys, guinea fowls, pheasants, etc., are more resistant to the virus.
Interestingly, waterfowl geese and ducks have good immune defenses against pseudoraums and avoid dangerous infections.
The pseudo-pests virus differs from its “progenitor” - the classical plague, and the organisms of many species of birds are resistant to the plague, but are defenseless against the mutated virus that causes Newcastle disease (pseudo-plague).
History reference
In far Italy, in 1878, a strange bird disease was discovered that paralyzed and killed them in a matter of days. It was a classic plague virus, which later took the form of pseudo-pills.
The disease, without meeting the active opposition of perplexed farmers, began to spread very widely to all countries of the world.
In 1926, it was registered in the eastern part of India, and to date, its outbreaks have been seen on all continents of the globe.
Pathogens
Pathogens belong to the group of paramykviruses. Their viability in poultry houses is maintained in the winter season up to 140 days, in summer - up to one week.
In carcasses prone to freezing, the virus lives up to 800 days, in decaying corpses it is subjected to inactivation after a three-week period.
Course and symptoms
Newly infected birds, as well as individuals who have already had a disease, become sources of viral infection.
Pathogens are contained in fluids secreted by sick chickens: saliva, vomiting.
They are also in the eggs of a sick bird.
Even in the air that a chicken exhales, a virus is also detected.
Healthy individuals easily become infected through feed and water.In which there is a virus pseudo-voices.
The workers of the poultry farm do not even suspect that, having visited other farm lands where pseudo-rages rage, they can easily bring dangerous microorganisms on their clothes and shoes.
Infected eggs received for incubation will cause the death of many birds in the compound. Chicken mites and wild birds are also carriers of the disease.
The virus, in contact with the body of the bird, tends to get into the blood and quickly begins to multiply in it, causing sepsis. The walls of blood vessels quickly thinning, there are numerous minor hemorrhages. These processes instantly destroy the nervous system and all the internal organs of the chicken. The virus is active 2-14 days after infection.
Chickens have a sharp rise in body temperature. They become drowsy and indifferent. Feathers are ruffled, fetid viscid mucus flows from the nasal and oral cavities.
Excrement - often mixed with particles of blood, have a greenish-yellow color. Chickens cough, they hardly give each sigh, when they try, each time they make a gurgling, bubbling sound.
When the nervous system is affected, bird movements become uncertain and uncoordinated. Often there are leg cramps, paralysis. For 1-4 days the disease literally "eats" the birds, and they die.
Adults are stronger and more resistant to the virus; therefore, some of them survive, if the disease has a chronic course. In this case, the birds need only a few weeks (usually up to 3) to overcome the pseudo-slime.
Not many people in Russia today are familiar with the Alsatian hens. And in vain! Do not be one of them!The page //selo.guru/ptitsa/bolezni-ptitsa/virusnye/stafilokokkoz.html fully describes the disease of staphylococcosis of birds.
Diagnostics
If a noticeable decrease in the appetite of birds is noticed, the cornea of the eyes becomes turbid, the chickens begin to sneeze - an alarm should be sounded urgently. Diarrhea, stray gait, leg cramps and a constantly open beak will quickly add to the signs of the disease, suggesting that the chickens are infected.
A laboratory examination of the blood and internal organs of diseased individuals reveals a dangerous pseudo virus.
Treatment
Unfortunately, many treatments fail in combating pseudo-pills.
Therefore, only timely preventive measures and vaccination at different stages of growing chickens can save domestic birds.
The virus does not respond to environmental changes. Whether it is the hot, scorching rays of the sun or a strong winter frost - the microorganisms remain viable.
And only when a certain chemical substance is exposed to the virus does it die. Formalin solution, carbolic acid, caustic soda and alcohol cope with it quickly and irrevocably.
Prevention and control measures
When detecting the first signs of disease in birds, it is urgent to isolate sick individuals from healthy ones.
The quarantine imposed on the farm avoids the further spread of pseudo-patches.
Infected chickens and having contact with them chicks are killed and then burned.
Among adult individuals, only sick hens are selected for burning. The rest are killed, and meat is consumed only in a well-cooked form. Birds are vaccinated immediately.
Litter in an empty house must be collected and burned too.. For the treatment of the premises using a 5% Creolin solution or 2% sodium hydroxide. Quarantine lasts for a month, after which disinfection is performed again.
Small chicks are defenseless against various pathogens and adverse environmental factors.
In order to successfully engage in poultry farming, it is necessary to take preventive measures in a timely manner and be sure to vaccinate chickens that allow their immune systems to produce antibodies and be stronger and more secure.
