Abstract

The conservation of Siberian tigers, the apex predators in the Asia-Pacific region, hinges on a thorough understanding of their physiological statuses and adaptive mechanisms. In order to fill a critical gap in our knowledge of this endangered species, we conducted comprehensive analyses of Siberian tiger whole blood and serum using modern hematology and biochemical analyzers. The blood samples were collected from subadult (2-3 years old) Siberian tigers (n = 15 for hematological analysis and n = 7 for biochemical analysis). In the present study, distinct hematological patterns including an elevated mean platelet volume (MPV) and a higher red cell distribution width coefficient of variation (RDW-CV) were observed, which were possibly triggered by pre-anesthesia resistance movements. Notably, the neutrophil percentage in Siberian tigers was found to be significantly higher than that in domestic cats and Bengal tigers, suggesting species-specific immune adaptations. In addition, serum biochemical analysis provided refined parameter ranges for subadult tigers. Unlike previous studies encompassing a broader age range, our data specifically characterize biochemical profiles in subadult tigers, offering vital baselines for health monitoring and conservation strategies. These results not only enhance our understanding of the biology of Siberian tigers but also provide scientific support for targeted conservation efforts, fostering population recovery and ecological balance in their natural habitats.

圈养东北虎亚成年的血液学和生化指标。

东北虎是亚太地区的顶级食肉动物，对其生理状态和适应机制的深入了解是保护东北虎的关键。为了填补我们对这一濒危物种知识的关键空白，我们使用现代血液学和生化分析仪对东北虎全血和血清进行了全面分析。采集亚成年（2 ~ 3岁）东北虎的血液样本（血液学分析15只，生化分析7只）。在本研究中，观察到明显的血液学模式，包括平均血小板体积（MPV）升高和红细胞分布宽度变异系数（RDW-CV）升高，这可能是由麻醉前抵抗运动触发的。值得注意的是，西伯利亚虎的中性粒细胞比例明显高于家猫和孟加拉虎，这表明它们具有物种特异性免疫适应性。此外，血清生化分析为亚成年老虎提供了更精细的参数范围。不像以前的研究涵盖了更广泛的年龄范围，我们的数据特别描述了亚成年老虎的生化特征，为健康监测和保护策略提供了重要的基线。这些研究结果不仅提高了我们对东北虎生物学的认识，而且为有针对性的保护工作提供了科学支持，促进了东北虎种群的恢复和自然栖息地的生态平衡。

期刊介绍： Animals (ISSN 2076-2615) is an international and interdisciplinary scholarly open access journal. It publishes original research articles, reviews, communications, and short notes that are relevant to any field of study that involves animals, including zoology, ethnozoology, animal science, animal ethics and animal welfare. However, preference will be given to those articles that provide an understanding of animals within a larger context (i.e., the animals'' interactions with the outside world, including humans). There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental details and/or method of study, must be provided for research articles. Articles submitted that involve subjecting animals to unnecessary pain or suffering will not be accepted, and all articles must be submitted with the necessary ethical approval (please refer to the Ethical Guidelines for more information).
