Inadequate and uniform nutrition leads to a disease of the stomach and intestines (gastroenteritis) in both young and adult birds. Due to hypothermia, prolonged transport or a large delay in feeding in young animals
there is massive gastroenteritis. The disease is also possible due to rancid and poor-quality feed, contaminated water, against the background of infectious diseases. Signs of the disease are growth and development retardation, a dull, ruffled, untidy plumage.
The disease can be judged by the liquid stain, which becomes watery, mucous, contains undigested grain, impurities of the blood, has an unpleasant odor.
In sick birds, untidy plumage, near the cloaca, it is covered with crusts. Birds sit, with their eyes cracked, eyes without glitter and are half-closed, rapid breathing (normal 25-40 respiratory movements once a minute), heart rate is also increased (normal - 140 beats per minute), wings are lowered, pigeons have poor or no appetite absent, body temperature increased (normal - 40.5–42.5 ° C).
What is chicken gastroenteritis?
Gastroenteritis is a disease of the stomach and small intestine.. This internal disease has other names, for example, stomach or intestinal flu.
Gastroenteritis in chickens can be acute and chronic. If we talk about the acute form of the disease, then it has several subspecies. Among them there is a viral subspecies, infectious, alimentary, toxic, allergic. All these subspecies and forms have approximately identical symptoms, but the sources of infection are completely different.
Hazard and damage
Gastroenteritis was once considered exclusively a human disease, after which the disease has become common in cattle, and today it affects both birds and pets.
Gastroenteritis is an insidious disease, because many poultry farmers, observing the characteristic symptoms, take a serious ailment for ordinary poisoning. This can lead to the fact that the disease will spread to all chickens, both adults and young animals.
If gastroenteritis is caused in one of the birds by food allergies, poisoning, the use of low-quality raw materials, then you can not worry about other chickens, but just in case, observe their condition and carry out preventive measures. But if gastroenteritis is viral in nature, then all birds are at high risk of infection.
The risk of infection with gastroenteritis, especially viral, is extremely high. Rapid depletion leads to the inevitable death of poultry, which directly affects economic damage.
Infectious gastroenteritis is most often found in the industrial sector, where poultry farmers cannot always detect the disease due to the large number of chickens. Serious damage at the initial stage of the onset of the disease is associated with the departure of chickens. The body weight of the diseased bird will not increase, but on the contrary, the chicken can lose weight, which entails a decrease in performance.
Causative agents of the disease
Gastroenteritis in chickens can be caused by various pathogens.
The most common cause of the development of the disease is irregular feeding, feeding low-quality grain.
Also, the stomach of a bird can be affected due to the ingestion of substances that irritate the intestines, for example, salts of heavy metals, drugs. The cause of the disease can be a banal food allergy to food.
Infectious and parasitic diseases are often the causative agent of gastroenteritis. Various defects of the stomach and intestines contribute to the onset of the disease, for example, a polyp, digestive disorders, ischemia of the wall of the small intestine, etc.
Course and symptoms
The main symptoms of gastroenteritis:
- Gastroenteritis in chickens is accompanied by varying strengths of depression, weakness, and blueness of the crest.
- If the degree of damage is acute, then liquid or foamy feces are observed, having a yellow-green color and a fetid odor. Often, undigested feed particles can be found in them.
- Feathers near bird cesspools are contaminated with feces.
- In a chronic case, gastroenteritis develops anemia, while diarrhea stops and intestinal atony and gas overflow occur.
- Sick bird refuses food.
- The body temperature of the bird is elevated, or is at the upper level of the norm.
- Thirst is absent or moderate.
Vomit contains mucus, bile, feed particles, blood. The mucous membrane of the mouth is covered with saliva, and a plaque of white or gray color forms on the tongue.
The wall of the abdomen of the bird is painful and tense, which can be felt during palpation. The feathers of the chicken take on a groomed appearance, sometimes drooping eyes.

Symptoms of gastroenteritis are similar to many other diseases of chickens, so you can not do without an accurate diagnosis. In order to establish a final diagnosis, virological and bacteriological studies are carried out.
The conditions of detention are assessed, and poultry feed is subjected to toxicological and mycological analysis.. Along with the above manipulations, feces of chickens are also subject to research.
Treatment of gastroenteritis begins with the elimination of the causes that caused this disease.
To do this, poultry is transferred to a semi-starvation diet using easily digestible food and vitamins.
Water in chickens should be exceptionally clean and fresh. If necessary, laxatives are used to completely cleanse the stomach of accumulated toxins.
With severe intoxication and dehydration, a solution of glucose is administered to the bird. To eliminate dysbiosis and suppress toxicogenic microflora, antibiotics are prescribed in combination with nitrofurans or sulfonamide drugs.
Prevention and control measures
- The main preventive measures are the organization of high-grade, high-quality nutrition, which will correspond to the physiological needs of birds.
Water should always be fresh, because it is with water that bacteria most often enter the body of a bird. Periodically it is necessary to arrange medical examination at poultry farms, and carefully monitor the condition of the digestive system of chickens.
It is recommended for the purpose of prevention to give chickens vitamins, chemotherapeutic agents, beneficial bacteria, as well as drugs to enhance immunity.
