(1) Milk-like feces: the feces are milky white, and the dilute water sample falls to the ground like milk. Chickens often excrete this feces from 6: 00 am to 10: 00 am. This is a characteristic stool with intestinal mucosal congestion and mild enteritis. This kind of feces is more common in chickens raised freely on the flat ground and after rain.
(2) Segmented feces: feces are accumulated, thin and segmented, and sometimes there is a layer of mucus (purulent substance) on the surface. The feces that have just been excluded are obviously separated from water (like feces in water), and most of them are black gray or light yellow. This is a typical stool of chronic enteritis, which is more common in chicks.
(3) watery stools: the digestive substances in the feces are basically normal, but they contain too much water, which leads to thin feces, which is a protective reaction of mild enteritis and chicken drainage to dissipate heat and maintain electrolyte balance in the body. The reasons include colibacillosis, low pathogenic avian influenza, renal branching, stress caused by sudden drop in temperature, high salt content in feed and high environmental temperature.
(4) Egg white-like feces: The feces are egg white-like, yellow-green, mixed with white urate, and there are few digests. Common in seriously ill chickens or Newcastle disease chickens.
(5) bloody stools: dark brown, tea rust, purple, or thin or thick stools are all characteristics of gastrointestinal bleeding. Such as upper gastrointestinal bleeding, dark brown feces, tea rust and water color. Lower gastrointestinal bleeding, purple or red stool. Common diseases include food and chemical poisoning, coccidiosis and early Newcastle disease.
(6) Meat-red feces: The feces are meat-red, piled up like carrion, and rarely digested. This is feces formed by exfoliated intestinal mucosa, which is common in the recovery period of tapeworm, ascariasis, coccidiosis and enteritis.
(7) Green feces: The feces are dark green or grass green, like cooked spinach leaves, and the feces are thin and mixed with yellow and white urate. This is common feces after some infectious diseases and heatstroke, such as Newcastle disease, cholera and leukoaraiosis. These feces are a mixture of bile and intestinal exfoliated tissues, so they are dark green or dark green.
(8) Yellow feces: The surface of feces is covered with a layer of yellow or light yellow urine, and there are few digests, sometimes all of which are yellow urine. This is the characteristic of liver disease. It is because the damage of hepatic lobules affects bile excretion, and bilirubin is formed after entering the blood and excreted with urine. Cecal hepatitis excretes such feces.
(9) White loose stool: White loose stool is very thin, mainly composed of urate, which is common in bursitis, paralyzed chickens, white dysentery, anorexia of sick chickens and uremic chickens.
