How to Diagnose Chicken Diseases by Abnormal Chicken Manure Color?

The manure of a normal chicken is a mixture of feces and urine, moderately soft and firm, mostly cylindrical or strip-shaped, brownish green, with white urate attached at one end, and no foul odor. The first dropping passed each morning is pasty and yellow-brown, which is a normal phenomenon. After a chicken falls ill, its manure color often becomes abnormal, and the disease can be preliminarily identified by observing the color of the chicken manure.

White Manure

When chicken manure is yellow-white or gray-white and pasty, not well formed, it may generally be pullorum disease or fowl cholera. In pullorum disease, sick chickens often pass sticky, lime-like manure that adheres to the cloaca, causing difficulty in defecation. In fowl cholera, sick chickens often have severe diarrhea and pass gray-white manure. When the manure is white or yellow-white and watery, mixed with white urate particles, it may be infectious bursal disease, and it is also seen in chickens with no appetite, paralysis, and uremia. In addition, inclusion body hepatitis, chicken paratyphoid, egg drop syndrome, and Pseudomonas aeruginosa infection can all show white watery thin manure. If milky white, milk-like manure appears, thin and watery, as if milk were poured on the ground, it is mostly seen in mucosal congestion, mild enteritis, or vibrio hepatitis.

????Blood-colored Manure

The most common cause of red manure in chickens is coccidiosis. Bloody manure in young chickens around 1 month of age is generally cecal coccidiosis. In the early stage of acute cecal hepatitis in chicks, manure with blood may be passed, and in the late stage of Leucocytozoon caulleryi infection, manure with fresh blood may be passed. Chickens with coccidiosis, tapeworm disease, roundworm disease, and those recovering from enteritis can also pass bloody manure, with the manure appearing flesh-red, like rotten meat. In addition, poisoning by inorganic or organic toxic substances can also cause intestinal bleeding and bloody manure. Necrotic enteritis, Newcastle disease, moldy corn poisoning, and others can also cause blood in chicken manure. Among the above diseases, except that cecal coccidiosis often has bright red bloody manure and is easy to identify, bloody manure caused by other diseases or causes is mostly dark red in appearance and must be carefully observed. In general, manure that is dark red, black, or tea-black is commonly seen in upper digestive tract bleeding, while manure that is red or bright red is mostly seen in lower digestive tract bleeding.

Black Manure

This is a type of bloody manure. Because black manure is often caused by bleeding in the anterior part of the digestive tract, such as the duodenum and small intestine, the manure is mostly black or tea-black in appearance and shows occult blood. If the manure is rust-colored and watery and mixed with urate, it is mostly seen in severe digestive tract bleeding caused by early Newcastle disease poisoning and other conditions. In addition, gizzard erosion caused by poisoning from rotten fish meal can also cause black manure.

????Green Manure

Green manure is formed by the mixing of bile and shed tissue cells from the intestinal tract, and the most common cause is Newcastle disease. Sick chickens generally pass sticky, foul-smelling green thin manure, with the manure appearing black-green, accompanied by symptoms such as depression, reduced appetite, and difficulty breathing, and later neurological symptoms, decreased egg production, and other symptoms. In addition, fowl cholera and Leucocytozoon caulleryi infection can also cause sick chickens to pass green manure, and colibacillosis, Marek's disease and lymphoid leukemia, fowl typhoid, chicken chlamydiosis, and laryngotracheitis can all cause sick chickens to pass green manure. If chickens eat excessive grass meal feed, the manure passed will also be green, but this kind of manure is relatively dry and hard and is easy to distinguish from the green manure of sick chickens.

Yellow Manure

Histomoniasis can cause chickens to pass ginger-yellow thin manure. Apricot-yellow manure is generally caused by streptococcosis. Pale yellow watery manure is caused by inclusion body hepatitis. Yellow-white thin manure can be caused by infectious bursal disease or chicken campylobacteriosis. Yellow manure or yellow-brown thin manure can be caused by furazolidone poisoning. Yellow sulfur manure has a layer of yellow or pale yellow urine covering its surface and is mostly seen in typhlitis and hepatitis. Zhuo Yiquan
