Baoli colorful pheasant anatomy summary

Pathological necropsy, as a basic method for diagnosis of diseases, is rapidly diagnosed, suitable for operation, and widely used in production. However, due to the wide variety of chicken diseases, similar diseases often appear in different diseases. Therefore, whether we can correctly identify them is the basis for us to make a correct clinical diagnosis. The following description of the identification of common lesions in production is provided below for reference.

1, subcutaneous edema

Edema is more common in the chest and abdomen and the inside of the legs. The exudate is mainly jelly-like. The exudate color is yellow-green or blue-green, which is Pseudomonas aeruginosa disease, selenium-vitamin E deficiency. The exudate color was yellow-white for chicken cholera. The color of the exudate was blue-purple for staphylococcal disease.

2, chest and muscle bleeding

Bleeding is spotted or patchy. Common diseases include infectious bursal disease, fowl cholera and staphylococcal disease. In addition, vitamin K deficiency, sulfonamides poisoning, aflatoxin poisoning, inclusion body hepatitis, live leukocyte disease can also see muscle bleeding.

3, trachea, laryngeal lesions

Trachea, larynx disease often mucosal congestion, hemorrhage, trachea, throat mucus exudate. The disease is mainly seen in respiratory diseases. Mucosal congestion, tracheal exudate infectious bronchitis lesions. Diffuse hemorrhage of the throat and tracheal mucosa, with bloody mucus for infectious laryngotracheitis. Tracheal ring mucosa has bleeding sites for Newcastle disease. Septicemia mold, infectious rhinitis can also be seen in the respiratory mucus leakage and other diseases.

4, liver disease

The diseases that cause necrosis or necrosis in the liver include fowl cholera, chicken fleas, typhoid fever, acute E. coli disease, P. aeruginosa, spirochete disease, olaquindox poisoning, and nettle poisoning. The diseases that cause the liver to have gray nodules include Marek’s disease, poultry tuberculosis, chicken leukoplakia, leukemia, chronic aflatoxin poisoning, and live leukocyte disease.

5, intestinal bleeding

Gastrointestinal bleeding is a common symptom of many diseases in the acute phase, such as Newcastle disease, infectious bursal disease, fowl cholera, staphylococcal disease, streptococcal disease, necrotic enteritis, Pseudomonas disease, coccidiosis, bird flu, Poisoning and other diseases.

6, cecal lesions

The cecal lesions were mainly blockage of cheese-like material in the cecum. This disease suggested cecal coccidiosis, tissue trichomoniasis, paratyphoid, and chicken fleas.

7, glandular gastric mucosal bleeding

Newcastle disease can be seen between the mucosal papilla or nipple hemorrhage, infectious bursal disease, spirochete disease, mucosal bleeding at the junction of the muscle stomach and glandular stomach. The diseases that cause glandular and gastric mucosal bleeding include olaquindox poisoning, fulminant net poisoning, sulfonamide poisoning, bird flu, and inclusion body hepatitis.

8, urinary urate deposition

Diseases that cause kidney dysfunction can cause ureteral deposition of ureters, such as gout, infectious bursal disease, vitamin A deficiency, infectious bronchitis, ferret, spirochete disease, and long-term overdose of the drug.

9, ascites

Common diseases include ascites, E. coli disease, aflatoxin poisoning, selenium-vitamin E deficiency, chicken whitefly, paratyphoid, and yolk peritonitis.

10, myocardial nodules

This disease is mainly seen in E. coli granuloma, Marek's disease, chicken white fleas, typhoid fever, sulfonamides poisoning.

11, peritonitis

Mainly found in chicken E. coli disease, yolk peritonitis, chicken fleas, typhoid fever, fowl cholera, tissue trichomoniasis, septic mycoticosis. These are just some of the common clinical conditions. Clinically, due to the nature of the disease, the effects of vaccines or drug use, and the condition of the same disease under different conditions, there are also changes in the symptoms of the same disease, and some chickens may have complex complications of secondary or secondary diseases. Therefore, pathological changes should be analyzed dialectically during clinical diagnosis. The chicken disease does not exist in an arc, it is necessary to seize the key lesions, comprehensive overall necropsy changes, combined with comprehensive analysis of the flocks feeding management, epidemiology and clinical symptoms, it is possible to make the correct clinical diagnosis, thus providing control of disease Scientific basis
