    Abstract / Zusammenfassung

    The infusion of 5M NH4Cl caused an acidaemia (blodd-pH:7.32-7.36 calves; 7.32-7.34 young camels). This metabolic acidosis was accompanied by a respiratory compensation (PvCO2: 5.2-5.6kPa calves; respiratory rate: 30-65 breath/min calves and 13-20 breath/min young camels). The serum [SID3] (=[Na+]+[K+]-[Cl-]) decreased in calves on 38-44mmol/l and in young camels on 37-38mmol/l. The decrease in serum [SID3] could be due to hyperchloraemia (101-107mmol/l calves; 114-115mmol/l young camels) and a mild hyperkalaemia in calves (4.9-5.9mmol/l). The serum [Atot] (=[Albumin]g/l)x(0.123xpH-0.631)+[Pi]mmol/lx(0.309xpH-0.469) decreased in calves on 9-13mmol/l and on 11-12mmol/l in young camels. The decrease in serum [Atot] could be mainly due to hypophosphataemia (2.3mmol/l calves; 1.4-2.0mmol/l young camels) and hypoalbuminaemia (27.5-30.0g/l) in the young camels. Urine pH decreased on 5.3-5.6 in calves and on 6.0-6.7 in young camels.
