Haematological and biochemical parameters play important roles in safeguarding animal health and preventing disease, but the blood reference values of many wild animals are still unknown. Recently, few descriptions of the blood parameters of Siberian tigers (Panthera tigris altaica) have been reported because these tigers comprise an endangered species; however, it is extremely difficult to obtain blood samples necessary for these analyses. This study presents 14 haematological and 16 biochemical parameters of 133 Siberian tigers, of which 112 and 21 were from Heilongjiang Siberian Tiger Park (HB) and Hailin Siberian Tiger Park (HD), China, respectively. Our study is the first to determine the following parameters in Siberian tigers: red blood cell volume distribution width, platelet count, mean platelet volume, amylase (AMY), sodium/potassium, globulin and albumin/globulin levels. As the data for total bilirubin and AMY were not statistically significant, no statistical analysis was conducted for these parameters. Few parameters were significantly different according to sex and region (p < 0.05). The concentration of alkaline phosphatase decreased with age, whereas the creatinine (CREA) increased with age. The CREA concentration of tigers raised in HB was much lower than that of tigers raised in HD. The data obtained in this study provide a reference for monitoring the health of wild and captive Siberian tigers and will add important information to the standards for haematological and biochemical parameters of wild felines.
血液学和生化学参数在保障动物健康和预防疾病方面发挥着重要作用，但许多野生动物的血液参考值仍不清楚。由于西伯利亚虎（Panthera tigris altaica）属于濒危物种，因此最近很少有关于其血液参数的描述，但获取这些分析所需的血液样本极其困难。本研究提供了 133 只西伯利亚虎的 14 项血液学和 16 项生化学参数，其中 112 项来自中国黑龙江东北虎林园（HB），21 项来自海林东北虎林园（HD）。本研究首次确定了西伯利亚虎的以下参数：红细胞体积分布宽度、血小板计数、平均血小板体积、淀粉酶（AMY）、钠/钾、球蛋白和白蛋白/球蛋白水平。由于总胆红素和 AMY 的数据没有统计学意义，因此未对这些参数进行统计分析。根据性别和地区，只有少数参数有显著差异（p<0.05）。碱性磷酸酶的浓度随年龄的增长而降低，而肌酐（CREA）的浓度随年龄的增长而升高。HB 饲养的老虎的 CREA 浓度明显低于 HD 饲养的老虎。本研究获得的数据为监测野生和圈养西伯利亚虎的健康状况提供了参考，并将为野生猫科动物血液学和生化学参数标准增添重要信息。
