Please tell us how to avoid tuberculosis in chickens.
This is an infectious disease, which is characterized by the formation of specific nodules-tubercles in various organs and tissues.
The causative agents are three types of tuberculosis microbacteria: bovine, or cattle, human and avian. However, infection of people and animals with the inherent type of pathogen is possible.
The causative agent of tuberculosis retains its viability in manure for 7 months, in soil - more than 2 years, in river water - more than 2 months, in meat frozen and stored in a refrigerator - up to a year, in oil - up to 45 days, in cheese - up to 100, in milk - up to 150 days. However, boiling milk kills the pathogen after 3-5 minutes. The best disinfectants to combat tubercle bacillus are bleach with 5% active chlorine, a 10% solution of iodine monochloride, a 3% solution of formaldehyde.
Fortunately, eggs obtained from sick chickens are infected only in 1-5% of cases. Chickens hatched from such eggs die in the first months of life, or later they develop an active form of tuberculosis.
Infection with tuberculosis often occurs in the winter when crowded poultry. After all, poor conditions of detention, inadequate feeding reduce the resistance of the organism of birds to tuberculosis.
A characteristic feature of the course of the tuberculous process in chickens is the absence of calcified tuberculous nodules, which require a long time to form. Tuberculous foci in chickens develop more frequently in the liver, spleen, less frequently in the intestines and other organs.
The diagnosis of tuberculosis in chickens is established by the introduction of tuberculin into one of the beard of the bird (the second is the control). Education at the site of the introduction of tuberculin painful spilled swelling is regarded as a positive reaction, while the beard swells, hangs down, it becomes hot. Veterinary specialists use other methods of diagnosis.
Tuberculosis in chickens occurs chronically, with blurred signs. Sick chickens are usually inactive, despite the preserved appetite, quickly lose weight. Their comb and earrings are pale and shriveled. Oviposition is reduced, then terminated. When a neglected disease develops a long, debilitating diarrhea, which causes the death of the bird from exhaustion. With the defeat of the bones and joints, they swell up, are painful, the bird hardly moves. Often, sick chickens die suddenly as a result of a rupture of a heavily damaged liver or spleen.
Treatment of sick chickens is not economically feasible.
Prevention of tuberculosis is to create the most favorable conditions for feeding and housing for the birds. This is especially important because of the wide spread of the causative agent of tuberculosis in nature. If you suspect the presence of patients with tuberculosis of birds, it is necessary with the help of the veterinary service to conduct a thorough examination of all the inhabitants of the house.
After removing the sick bird, clean the coop and thoroughly disinfect the burned, low-value wooden inventory. After whitewashing the room, it is possible to place a new number of chickens in it.
For the prevention of disease, do not allow contact with domestic birds with wild birds and rodents, which are not only the mechanical vectors of the pathogen, but can themselves also suffer from tuberculosis.
Be sure to check carefully and people who were in contact with sick animals and birds.Read more articles on this topic here.
How to minimize the risks of chickens
During the cultivation of chickens make sure that they are not supercooled, because of a violation of the thermal regime, many diseases arise (aspergillosis, pullorosis, coccyrosis), kidneys become inflamed, and diarrhea appears.
It is important to properly keep the chicks.
Little chickens have almost no smell, so they are easily poisoned. Moreover, not only different plants, but also food. Pay attention to the quality and freshness of feed, for prevention it is desirable to add a little charcoal.
Add charcoal to chickens feed
Very often, chickens eat chaff or scoma along with food, and they plug the stomach. Large chickens in the stomach constantly have small pebbles that grind such tough food. Chickens do not bite pebbles, blockage can cause death. With a lack of fresh air, chickens suffer from lung diseases. The most dangerous is inflammation of the trachea or bronchi, such a diagnosis often leads to death.
Lack of vitamins causes a sharp deterioration in the health of chickens and impaired development. What diseases do chickens suffer from?
- Pullorosis. Chicks up to two weeks of age are ill. Appetite decreases, eyes close, wings fall. Death is inevitable.
In the acute form of coccidiosis chickens chickens die in 3-5 days
We became only a few of the most common diseases of chickens with one goal - to warn poultry farmers that the health of adult birds is formed from birth. If the chickens were sick, then the risks are high that in adult chickens the immunity is weakened, and they will also get sick if they violate the rules of keeping. If you want to have healthy laying hens - take care of their health from an early age.
Tuberculosis in poultry
You need to know that the birds will always have a waste. A completely healthy flock of laying hens in the winter period of time can give up to 10% of the case, you should not be upset, nothing can be done, this is normal. Chickens can become infected with infectious (most dangerous) or catarrhal diseases, suffer from various parasites. Consider the most common ones.
Pullorosis or false fever
Bedbugs, lice, worms and fleas
From a medical point of view, this is not a disease, but at the household level, the defeat of chickens by these parasites is also attributed to diseases. It must be remembered that the healthier a chicken is, the less likely it is that these organisms will parasitize on it. Parasites hide in the crevices of the building, striking birds at night. Bedbugs can be without food for six months, and their larvae up to one and a half years. At the same time, as soon as a “donor” appears, all vital properties resume. Such biological features greatly complicate the fight against them.
Fleas are very unpleasant parasites, should be disposed of with the help of ash baths or medicines. Ash baths should always be in the hen house, the birds will do their own preventive procedures. Prevention needs to be done in the fall, before transferring the flock to the hen house. In the same period should be disinfected and clean the room.
There is no sense to fight ticks, the bird needs to be killed, the room must be thoroughly cleaned and disinfected.
Effective antihelminthic drugs are used to destroy helminth parasites.
Worms in chickens: how to get out
There are several tips that will help to effectively prevent the occurrence of diseases, and it is much better than later to engage in their treatment.
- Try to breed the hens on your own from the eggs, and not to buy ready-made chickens. This will give you the opportunity to use only high-quality eggs.
Breed your own chicks
One Year Old Calico Chicken
Inspect Chicken Frequently
The more you pay attention to chickens from the first days of their life, the healthier you will be the number of chickens, the lower the incidence and mortality. If a bird is ill, then it will inevitably lag behind in development and will never yield the expected number of eggs.
Disease prevention - timely and competent vaccination. This is not a one-time action, but systematic work for at least one hundred days. Birds die from bacterial diseases, but they get sick more often after viral diseases. Viral ones weaken the immune system, pathogenic bacteria penetrate into the body and cause a lethal outcome.
Here is an approximate vaccination scheme for one of the poultry farms.
Chickens are one of the few animals, after the illness of which not the strongest survive, but only the weakened individuals. This is due to the fact that all diseases certainly have a negative impact on their further development indicators. Conclusion - if diseases are committed, then you should not hope for high egg production. The main task of veterinary medicine is not to cure diseases, and with the help of modern vaccinations of chickens to prevent their occurrence. And, of course, you need to adhere to the maximum recommendations for feeding and sanitizing chicken coops.
Why do chickens get sick: causes of diseases
Diseases of chickens occur when the vital functions of the body of a bird are disturbed under the influence of destructive environmental conditions.
The following are the main reasons why chickens are sick.
- Poor quality of feed, their contamination with various toxins, pathogenic microflora.
- The reason for the disease of chickens can be low nutritional value of feed.
- Sharp diet change.
- Disruption of the daily routine.
- Overcrowded chickens.
- Non-observance of a microclimate in a hen house: high or low air temperature, drafts.
- Also, the cause of diseases of chickens can be the presence in the air of the room of harmful gases (ammonia, hydrogen sulfide, etc.).
- Impact on the body of chickens pathogenic microbes, worms, etc.
So that your laying hens do not have any diseases, so that the birds give delicatessen products - meat and eggs, you need to protect them daily from the effects of the above factors.
Then you will learn how chickens get sick and how to treat them.
What diseases are chickens and video diseases
Diseases of domestic chickens are non-infectious and infectious (including invasive and infectious).
It is reliably known that 80-82% of the diseases of chickens in their personal farmstead are diseases of non-contagious origin. These are primarily avitaminosis and hypervitaminosis, macro- and microelementoses, inflammation of the goiter, oviduct, urine acid diathesis, poisoning, cannibalism, etc. Often, hens are diagnosed with diseases of helminthic and parasitic origin (coccidiosis, aspergillosis, skin parasites, etc.).
20-30% of diseases occur due to pathogens of infectious origin (pasteurellosis, tuberculosis, etc.).

It should be noted that the infectious diseases of chickens become less common. This applies to personal farmsteads. Here chickens are kept in isolation from wild birds and animals. Moreover, in contrast to the poultry farms, in the private household hens are bred in small quantities.
