Mineral and electrolyte concentrations in young red deer

Young animals of different species show different electrolyte and mineral concentration compared to adult ones. In order to establish the difference between young and adult red deer we determined the electrolytes and mineral concentrations (sodium - Na, potassium - K, chloride - Cl, total magnesium - tMg and calcium - tCa, ionized Mg - Mg2+, ionized calcium - Ca2+ and inorganic phosphorus –iP) in young deer population and compared them with adults.Serum electrolytes and minerals were determined in samples from 34 physically restrained, healthy young red deer (Cervus elaphus), aged 0, 5-2 years. The results were compared to values obtained from 11 adult animals. Serum tCa, iP and tMg were determined by spectrophotometric analysis using Olympus biochemical analyser (AU 6000) and original reagents of manufactorer. The Ca2+ , Mg2+, Na, K and Cl concentration were determined by ion-selective electrodes (ISE), using a acid-base analyzer (Nova Biomedical). Statistical analysis of the data were carried out by Student t-test at p<0, 05 significance level. Young animals showed significantly higher values of K, tCa, Ca2+, Mg2+ and iP, while Na and Cl concentration were significantly lower. There was no significant difference in the tMg concentration and Ca2+/Mg2+ ratio in relation to age. The obtained results demonstrate the need to use specific reference intervals for young deer population.
