Where does excess dietary protein localize to cause renal gout in brown layers, and what biochemical markers confirm renal failure?

Feeding commercial brown layers diets containing excess crude protein or imbalanced amino acids results in high nitrogen deamination. This excess nitrogen is metabolized into uric acid, which must be excreted by the kidneys. When the kidney's filtration capacity is exceeded, uric acid localizes as chalky white calcium sodium urate crystals (tophi) on the surfaces of visceral organs—including the kidneys, pericardium (heart sac), and liver—a pathological condition known as visceral gout. Clinical biochemistry showing elevated blood serum uric acid and blood urea nitrogen (BUN) levels confirms severe renal failure. Farmers can study renal physiology in the Poultry Encyclopedia, buy supportive kidney flushes and electrolyte balancers on Poultry Plaza, track daily egg and feed raw material rates on Poultry Rates, and trade healthy laying flocks on Murghi Mandi.
