Gout in poultry
Gout is a metabolic disease of poultry. it is originated by infectious and noninfectious origin. gout is also outbreaking as a seasonal disease in certain parts of the world in poultry.
We have already discussed the casual agents & etiology and clinical signs of gout of poultry. But, We are going to elucidate postmortem findings of gout in chicken
It obviously needs a diagnosis of gout. Without performing postmortem, we can not differentiate the actual etiology of gout in domesticated chicken.
Organs Identifying In Gout
Postmortem findings of gout is a non-specific organ to organs. It means postmortem lesions are seen in multiple organs including kidneys. Identifying of deposition of uric acid in various organs is a key point of postmortem findings in gout of poultry.
but one system of poultry severely affected and it is considered to be more specific which is a kidney.
Other internal organs for instance air sac, heart, liver, gizzard, peritoneum, small and large intestine are affected fully in some cases. Besides, in some other cases urate deposits in few organs including the kidney.
Lesion Types of Gross findings
It is basically divided into two types to identifying the lesion properly in a naked eye in the field during the postmortem of gout in poultry.
1. Visceral Urate Deposition
besides, two systems, the lower respiratory tract is affected such as the air sac, and a cardiovascular system like the heart also affected.
At primary stages, the kidney became yellow-whitish and ureter double in size
in the second Stage, lobulation of the kidney starting to redden due to congestion of blood by the excessive deposition of urate in the kidney.
In severe conditions, whitish chalky materials called uric acid highly deposited with reddening kidney tissue which easily separated by a naked eye during necropsy.
Uric acid Deposition on epicardium and pericardium in the heart of poultry
2. Articular Urate Deposition
It is a sporadic problem of little economic importance in poultry. the periarticular tissue is white due to urate deposition, and white semi-fluid deposits of urates may be found.
In chronic cases, urate precipitates also can be observed in the comb, wattles, trachea, etc.
