Ammonium chloride was added to diets varying in Ca content to evaluate its potential in preventing silica urolith formation in sheep. A 2 x 2 factorial experiment involved wether lambs with ad libitum access to a diet of 50% grass hay and 50% ground oats plus supplement. The basal diet contained on a DM basis 3.3% SiO2, .31% Ca, .22% P, 11.6% CP, and 26% ADF. Treatments (38 to 39 lambs/treatment) consisted of a control (C), limestone to increase dietary calcium to .6% (L), 1% ammonium chloride…

Silicon-zinc interactions and potential roles for dietary zinc and copper in minimizing silica urolithiasis in rats.
It is demonstrated that Zn deficiency and, to a lesser extent, Cu deficiency contributed to silica urolith formation in rats fed diets having a high content of absorbable Si, as indicated by a 23% Si-mediated weight gain response in Zn-deficient rats.

Use of ammonium chloride to prevent urolithiasis in sheep
ABSTRACT Urolithiasis has a high incidence among confined sheep. It is multifactorial and may cause economic damage. Our aim was to determine the capacity of urinary acidification using ammonium
Inclusão de cloreto de amônia na dieta pré-parto de ovelhas leiteiras e sua influência nos metabolismos do cálcio e energético* Inclusion of ammonium chloride in the pre-partum diet in dairy sheep and its influence on calcium and energetic metabolism
This research was done to evaluate the effect of inclusion of ammonium chloride in the pre-partum diet in dairy sheep over the urinary pH and in calcium and energetic metabolism of these animals.
The Impact of Nutrition on the Development of Urolithiasis in Captive Giraffes and Meat Goats.
It can be concluded that feeding the ADF-16 diet, produced a trend of high urinary P, high serum P and a tendency for a high crystal count in the urine over the four week experimental period, which can be considered strong risk factors for the development of phosphatic uroliths.
Avaliação clínica, laboratorial e anatomopatológica do sistema urinário de ovinos confinados com ou sem suplementação de cloreto de amônio
It was concluded that the highly concentrated diet caused renal injury in both groups, without changing the renal function, what was proven by laboratory tests of urea and creatinine.
Aetiopathogenesis of Bovine Obstructive Urolithiasis
Investigation on clinical studies on obstructive urolithiasis in cattle calves in India found high concentrate feeding with little provision of water during winter months seemed to be the most prominent predisposing factors for the development of the disease.
Obstructive urolithiasis in a flock of male weaner sheep at an organised farm in semiarid Rajasthan
It is concluded that during summer months lack of fiber intake and increased dependence on concentrate feed would have played a role in predisposition of obstructive urolithiasis exclusively involving such a large number of male hoggets for the first time in the history of the institute.


Chloride and phosphate as impediments to silica urinary calculi in rats fed tetraethylorthosilicate.
Rats fed a dextrose-casein type of diet adequate for normal growth and containing 2% of tetraethylorthosilicate (TES) were used to study the effect of NaCl and Na2SO4 drinking waters, and dietary
