An outbreak of gout was recorded during October to November, 2015 in a flock of Giriraja breeder chicks maintained under intensive management system that resulted in mortality of 55 birds in a flock of 2000. Both visceral and articular gout were observed simultaneously. Grossly, dry platery patches of white chalky deposits were observed on the serosal surfaces of pericardium, liver, kidneys and ureters. Microscopically, kidneys showed varying degree of urate crystal deposition amidst an intense granulomatous inflammatory reaction. In addition, pericarditis and hepatitis were the other predominant lesions. The findings of positive murexide test, demonstration of needle shaped urate crystal under phase contrast microscopy and urate crystals by De Galantha staining method on tissue sections of affected organs were confirmatory of gout. Exclusion of concentrate feed and provision of additional drinkers, incorporation of low protein diet, jaggery mixed water, supplementation of A, D3, K, B complex and electrolytes helped in control of gout and mortality of chicks.
