[Experimental paroxysmal hemoglobinuria in calves and selected biochemical indicators in the blood and urine].
When examining diseased calves, sporadically pronounced haemoglobinuria with dark red urine can be observed. In serious cases the clinical picture may be manifold but peculiar; in easy cases, however, when there are no distinct clinical symptoms, a larger scale of examinations is needed to aid differential diagnosis. Eight roughage-fed bulls aged two months, weighing 55-71 kg were used in this experiment. Selected biochemical indices of the mineral, enzymatic, hepatic, energetic and urinary profile were determined in the blood serum and urine of the animals. After the administration of cold water at an amount representing 12% of the animal's body weight, ionogram values were determined. In all indices a positive correlation with hydraemia and a decrease in Na, Cl, Ca, Mg and P levels were observed. Correction of the above levels occurred within 24 hours, with the exception of Na and P concentrations that did not reach starting values. As to the enzymatic profile (AST, ALT, GGT), no pronounced disturbances could be observed. The most profound changes were seen in AST activity that increased in the 5th hour of the experiment. A slight tendency towards hypoproteinaemia was observed to continue even in 24 hours. Hypoglobulinaemia reached its starting value in the 24th hour while simultaneously albumin levels slightly increased. The increasing bilirubin levels reached their maximum in the 5th and 6th hour; correction of the former occurred within 24 hours. The urinary profile revealed polyuria, aciduria, aquaeous urine and haemoglobinuria, the latter reaching its peak between hours 1 and 3 following water administration.(ABSTRACT TRUNCATED AT 250 WORDS)
