The aim of this study was to analyze the annual concentration of some biochemical parameters in the blood plasma of brown hares (Lepus europaeus). During the course of a one-year period 36 male and 38 female adult hares were analyzed. The highest concentration of calcium in blood plasma was recorded in the summer with significant differences (p < 0.05) between the summer and autumn and between the winter and spring periods. The concentration of phosphorus in blood plasma manifested seasonal oscillations, the highest concentration being recorded in the summer. The Ca : P ratio changed slightly during the year. Differences in the concentration of plasma magnesium were found depending on the season; significantly higher concentrations of magnesium were found in the autumn (1.63 mmol.l⁻¹) than in winter (1.37 mmol.l⁻¹). The concentration of sodium ranged from 142-158.2 mmol.l⁻¹. There was also a significant difference in the content of this parameter between the summer and autumn. The lowest sodium concentration was detected in the autumn and the highest in summer. In the winter the highest concentration of potassium (9.80 mmol.l⁻¹) in the blood plasma of hares was measured. The Na : K ratio decreased from spring to winter. The average concentration of glucose in the blood plasma of hares ranged during the whole year from 5.72 to 8.99 mmol.l⁻¹. The highest content was found in June and the lowest in September. The annual average year concentration of urea was 5.00 mmol.l⁻¹, with the highest amount in the spring. A significantly higher cholesterol concentration was measured in the spring than in summer. The concentration of total proteins in blood plasma achieved the average value of 56.49 mmol.l⁻¹ and a significant difference was recorded in spring and summer. In total lipids, a significant difference was calculated between the spring (1.46 g.l⁻¹) and summer (0.91 g.l⁻¹). The highest amount of bilirubin was found in the spring (4.25 µmol⁻¹) and the lowest in autumn (3.70 µmol⁻¹), with an average concentration of 3.97 µmol⁻¹. Depending on the season the highest ALT and AST concentration was in spring and the lowest in summer. Annual differences in blood biochemical parameters of brown hares found in this study reflect the actual nutritional and health status as well as the ability of physiological adaptation to the appropriate seasonal period in relation to food intake, condition, health status and stress effect.
