Abstract: To establish a reference range for the blood physiological indicators of the giant pandas (Aluropoda melanoleuca) and make comparisons between sexes and among age groups. A total of 120 giant pandas were used in this study and were divided into four age groups:old,adult,sub-adult,and juvenile. Five hundred blood samples (75% from females and 25% from males)were collected from the pandas for comprehensive analyses. The red blood cell count,white blood cell count,absolute neutrophil count and hematocrit (HCT)value of the male pandas are significantly higher than those of the female pandas (P <0. 05).The mean corpuscular volume (MCV)and mean corpuscular hemoglobin (MCH)of the male pandas are significantly lower than those of the female pandas (P <0. 05). The differences in other physiological indicators between the male and female pandas were not statistically significant (P > 0.05). Significant differences on some indicators were also found among different age groups (P < 0. 05).
