Abstract

The giant panda (Ailuropoda melanoleuca) is one of the most endangered species of land mammals and has significant academic research value worldwide. The evaluation of hematological parameters in giant pandas is important for assessing the physiological status of animals. This study collected blood samples from 12 healthy giant pandas from September 2018 to August 2020 under non-anesthetic conditions. The samples were then analyzed for basic blood indices and blood rheology, and normal values for hematological parameters and blood rheology under non-anesthetic conditions in giant pandas in Beijing area were obtained. The study confirmed the influence of age and season on hematological and biochemical parameters in captive giant pandas: hematological morphology, blood rheology, and serum enzymes showed seasonal variations, while age affected the changes in serum enzymes, serum protein content, and serum metabolite content. There are significant differences in blood indicators among different age groups of giant pandas, indicating variations in the overall metabolic processes and differences among pandas of different age groups. Seasonal variations showed a regulatory effect on blood rheology parameters and a negative effect on blood viscosity. Further research should be conducted to investigate whether factors such as season and climate cause environmental stress in captive giant pandas. The results obtained in this study aim to better protect the stability of the giant panda population and provide references for the appropriate feeding and medical care of captive giant pandas.
