The reasons for management:
1. The chickens are cold. Chilled chickens can cause intestinal peristalsis to increase and speed up, resulting in diarrhea.
2. The ventilation of the chicken house is poor, and the ammonia concentration exceeds 20ppm, which can cause diarrhea.
3. Abusing electrolytes can cause the electrolyte concentration in the intestinal cavity to be too high and the osmotic pressure to increase, causing watery diarrhea.
4. Indiscriminate use of antibiotics will cause intestinal flora imbalance, reduce beneficial microorganisms, and increase pathogenic bacteria and cause diarrhea.
The reasons for diet:
1. The protein concentration is too high, causing indigestion and diarrhea.
2. Fatty acid in the feed can cause gastrointestinal dysfunction and diarrhea.
3. The concentration of potassium, sodium and calcium ions is too high. Such as salt poisoning, diarrhea caused by suddenly eating high-calcium feed, it is caused by high concentrations of sodium ions and calcium ions.
4. Eating moldy and deteriorating feed or drinking water causes diarrhea due to fungal enteritis.
5. Drinking bitter water with high hardness and high salinity can cause diarrhea.
The cause of the disease:
1. Viral diseases: such as avian influenza and Newcastle disease, chickens can have yellow-green loose stools and diarrhea. Rotavirus can cause watery diarrhea. In infectious bursal disease, renal abortifacients cause white, loose stools due to swelling of the kidneys.
2. Bacterial diseases. Such as common Escherichia coil, Salmonella, Pasteurella can cause diarrhea. Bacterial diarrhea is often accompanied by characteristic clinical manifestations. For example, Escherichia coil is often seen in pericarditis, perihepatitis, air sac inflammation, and yolk peritonitis. Salmonella often shows hepatosplenomegaly with white necrotic foci. Pasteurella often sees hemorrhage in the fatty sulcus of the heart and needle-like white necrosis in the liver.
3. Diarrhea caused by parasitic diseases. Parasitic parasites in the gastrointestinal tract of chickens, such as coccidia, tapeworms, and nematodes, continuously destroy the mucosa of the gastrointestinal tract, destroying its normal form and function. Cause severe digestion, malabsorption, resulting in chronic diarrhea. If not targeted deworming, long-term cure, diarrhea caused by parasites is often accompanied by anemia, mucous membranes and cockscomb white. Sometimes blood in the stool or tomato-like stool.
4. Diarrhea caused by fungi. The feed and drinking water is contaminated by mold and ingested into the body, the house is damp, the objects are moldy, and the mold spores are dispersed in the air and inhaled by the chickens, which can cause fungal enteritis and cause diarrhea.
5. Comprehensive pathogenic factors. Clinically common enterotoxin syndrome. It is manifested as diarrhea, meat-like feces, and overfeeding, which is caused by comprehensive pathogenic factors. It is the result of the combined action of enteroviruses, Escherichia coil, Clostridium welchii, and Coccidia.
