title: Analysis of the urine of the okapi (Okapia johnstoni).
abstract: The urine of six adult and two juvenile okapis housed in The Royal Rotterdam Zoological and Botanical Gardens were analysed qualitatively for the presence of protein, glucose, bilirubin, nitrite, blood and ketones and the pH was measured. Quantitative analyses were undertaken for osmolality, urea, creatinine and glucose. The results of the analyses were generally unremarkable with the exceptions of pH, glucose and in some cases the urea/creatinine ratios. However, with the exception of the glucose these other results are physiologically normal. One possible explanation for the presence of glucose in the urine of the okapis is dietary. In the wild these animals are folivorous and thus they may not be able to cope with the high level of sugar presented to them in their captive diet. However, it must be emphasised that this condition has no apparent ill effects on the animals which are in good health and are breeding successfully.
