Approximately 80 farmed male and female red deer aged three months and over were blood sampled and biochemical parameters measured. The deer were sampled by jugular venepuncture without tranquillization. Mean values recorded were serum gamma-glutamyltransferase (19.5 IU/I), glutamic oxaloacetic transaminase (43.0 IU/1), creatine Phosphokinase (197.9 IU/I), plasma pepsinogen (0.91 IU/1), blood urea nitrogen (8.56 mmol/1), serum glucose (6.9 mmol/1), phosphorus (1.75 mmol/I), calcium (2.13 mmol/I), magnesium (0.74 mmol/1), potassium (4.43 mmol/1) and sodium (138.5 mmol/I). There were no significant differences in any parameter between sexes or between age groups 3-8 months, 9-18 months, or older.
