Online Published on 5 January, 2024. Abstract Background Serum electrolyte monitoring is essential in the health assessment of captive elephants. The major elements of calcium, sodium, potassium, chloride and bicarbonate are playing a major role in regulation of nerve and muscle functions and in maintaining acid base and water balance. Excess levels or loss of particular electrolytes may occur as secondary changes caused by certain diseases or changes in physiological regulations. The aim of this study was to evolve the baseline reference values for serum electrolyte levels in captive Asian elephants raised in Tamil Nadu state of India. Methods As part of the periodical health assessment blood samples were collected from auricular vein for 42 apparently healthy captive Asian elephants in Tamil Nadu, India. Serum electrolyte levels such as sodium (Na+), potassium (K+), chloride (Cl-), ionized calcium (iCa), non-ionized calcium and total calcium (tCa) were determined by using an automated electrolyte analyzer. Result Most of the ranges of electrolyte values observed in this study were similar to that of previous reports. As not much studies on ionized calcium are available on captive Asian elephants the value of ionized calcium found this study 1.16±0.13 mmol/L could serve as reference. There was no much variation observed in various age groups. This electrolyte profile values will serve as baseline values to evaluate the health and clinical conditions of captive elephant populations.
