Effect of dietary ammonium chloride and vitamin A on urolithiasis in sheep fed high concentrate ration.
Abstract: Eighteen Crossbred ram lambs (1/4 finnish Landrace X 3/4 Rahmani), of nine months old, were divided into three similar groups, each of 6 lambs to study of dietary supplementation with vitamin A ( 3000 1U/l kg diet) and / or ammonium chloride (5g NH4-Cl/1kg diet) on formation of urinary calculi during summer season. The studied parameters were; Nutrient digestibility, nutritive value of the experimental rations, feed consumption, feed conversion ratio, change in body weight, water consumption, urine volume, nitrogen balance, blood serum and urinary calcium, inorganic phosphorus, magnesium, sodium and potassium and urine sediments including pus cells, epithelial cells and triple phosphate.
Addition of ammonium chloride alone or with vitamin A resulted in better nutrient digestibility and nutritive value and improved feed conversion ratio. No significant differences in feed intake (DMl) was noticed. Body weight was significantly increased with the addition of ammonium chloride + vitamin A compared with ammonium chloride alone or the control group. Water consumption, during the entire experimental period, showed non significant differences among the experimental groups. However, the treated groups tended to consume more water than the control group. Nitrogen retention of treated groups was lower (P< 0.05) than the control group.
Addition of ammonium chloride alone or with vitamin A increased (P<0.0l) serum calcium level and urinary calcium level (P< 0.05) while decreased (P<0.01) serum urinary inorganic phosphorus level and magnesium but had no significant effect on blood serum and urinary sodium and potassium.
Addition of ammonium chloride with vitamin A maintained almost constant low count of pus cells and epithelial cells compared with ammonium chloride alone and control group but the triple phosphate count in both treated groups was maintained almost low (P<0.0]) compared with the control group.
