ABSTRACT
Azizi S, Ghalebi
SR, Kheirandish R, Nejad
FM, Mohajeri FA., Gout in a flock of ostriches fed
high calcium and protein diets, Onl J Vet Res., 21(6):288-292, 2017. Gout is associated with abnormal
deposition of urates in different tissues of human, reptiles and birds and
occurs as visceral and/or articular gout. In poultry, gout is an important cause
of mortality.
We describe gout in a flock of ostriches fed a diet with 2.9% calcium, 0.9%
phosphor and 19% protein. Upon gross examination, white chalky materials were
evident in joints and serosal surfaces of kidneys, intestines, pericardium and
air sacs. Microscopy
revealed parenchymatous interstitial nephritis with
deposition of feather-like urate crystals. Findings suggest
that high dietary
calcium and crude protein concentrations may cause visceral and articular gout
in growing ostriches.
