FEED SUPPLEMENTATION BY AMMONIUM CHLORIDE ANDIOR VITAMIN "A" TO CHECK FORMATION OF URINARY CALCULI IN SHEEP

This study was carried out to estimate the effect of ammonium chloride andlor
vitamin "A" supplementation on checking formation of urinary calculi in rams. Twenty
four rams were used in four equal groups each of six animals. The first group was
supplemented with ammonium chloride (5 gm/kg of diet). the second group was
supplemented with vitamin "A' (3000 IUlkg diet), the third group was supplemented by
ammonium chloride (5 gmlkg diet) plus vitamin "AM (3000 IUlkg diet) while the fourth
group remained as control. Ration. water and serum were analysed for their contents
of minerals related to urinary calculi formation. The results showed that there were
mineral's imbalances in the basic ration and. as well in the blood serum of the control
group. Supplementing rams with ammonium chloride and/or vitamin "A" improved
mineral content and reduced the imbalances in calcium ; phosphorus ratio and
sodium, potassium and magnesium concentration in blood serum. Determination of
pus cells. epithelial cells, red blood cells and triple phosphate crystals in the urine
revealed that these parameters were decreased after supplementation with vitamin
"A" and ammonium chloride. mostly through improving ca" ; P'" ratio in blood.
