Broiler's high-protein gout disease is caused by nucleic acid protein metabolism disorders and kidney damage, resulting in the accumulation of a large number of its metabolites, uric acid or urate, in the body. It is characterized by weight loss, joint swelling, and dyskinesia in clinical practice.
1, the incidence of the situation
A chicken farmer purchased 1,000 AA broiler chicks in mid-September 2007. The early chicks grew well. By the 15th day of age, some chickens had lameness and white diarrhea, and chickens died on the fourth day of illness. There were as many as 168 deaths.
2, clinical symptoms
Diseased chickens are in a better state of mind, able to eat and drink, joints swollen and swift, immobile gait gait instability, and white cloaks around cloacas.
3, anatomical changes
The cloacal cavity was squeezed out of the white excrement. White lime-like substances adhered to the surface of the thoracic balloon, chest wall, epicardium, peritoneum, mesentery, and liver. They could not be exfoliated; the kidneys were swollen and stained; the joint cavity contained white lime. substance.
4, laboratory tests
Aseptically, liver, kidney and spleen of diseased chickens were examined by laboratory smear staining. No pathogen was found.
5, diagnosis and treatment
According to the broiler growth and development characteristics, clinical symptoms, anatomical changes and laboratory tests, diagnosed with broiler gout.
1 Adjust feed and reduce protein levels in feeds;
2 Add vitamin A in drinking water and give enough water;
3 Add amoxicillin and Hua Shen Bao to the feed, and use it separately in the afternoon and afternoon;
Through the above comprehensive treatment, the disease was basically controlled on the third day of treatment, and no deaths occurred on the sixth day.
6. Summary
The disease is mainly caused by chickens using a protein and excessive calcium feed, coupled with poor ventilation in their brooding room, excessive humidity caused by hypoxia, resulting in a large accumulation of uric acid in the body, and can not quickly excreted Therefore, the urate is deposited on the surface of the joint capsule, the thoracic cavity and the visceral organs, and causes the disease. The disease currently has no specific therapeutic drugs and should be mainly prevention.
In clinical practice, gout caused by a combination of high-calcium and high-protein diets and gout and other nephritis are common diseases. It is worth noting that our full-rate feed quality is qualified, but often due to farmers adding other ingredients at will, or Poultry feeds are not strictly applied at the age of the poultry, or the chicks start eating prematurely because of impaired digestive function. Therefore, we must scientific management in order to raise a good chicken.
