Investigating serumic valeus of some electrolytes and enzymes of the healthy mule (Equus mulus) in relation to age and sex

This research was conducted to determine some blood serumic electrolytes and enzymes in apparently healthy mules living in temperate geographical conditions of northwestern Iran and the effect of age and sex on these parameters. The studied animals (51 males and 48 females) which ranged in age from 4 to 12 yaers, were divided into three similar age groups. The serumic values of sodium (mmol/L), potassium (mmol/L), chloride (mg/L), phosphorous (mg/L), and activities of AST (IU/L), ALT (IU/L), ALP (IU/L), GGT(IU/L) and CPK(IU/L) were 137.55±6.02, 4.06±0.55, 104.01±3.46, 2.69±0.35, 409.95±44.82, 17.96±2.25, 510.83±70.24, 31.27±4.52 and 295.56±38.76 respectively. Gender had no significant effect on the studied parameters (p>0.05). There were significant differences between different age groups (p
