The Shetland ponies, which originate from harshest environments in the world islands in the north of the Atlantic Ocean, are now most popular pony breed distributed in almost every corner of the world. Reference ranges of physiological, biochemical and haematological values, which are widely used in veterinary clinics, may differ according to season, age, sex, type of feeding, and environmental circumstances of the area. Reference ranges of haematological and biochemical values of Shetland ponies are rare. The present study was therefore undertaken to evaluate the impact of season, age and sex on some haematological and biochemical values and cortisol levels in healthy ponies in Saudi Arabia. The study was conducted between December 2016 to June 2017 on ponies in and around Al-Hasa, Saudi Arabia. Twenty-three clinically healthy ponies males and females of different ages were included for haematological and biochemical analysis in this study. For each animal, blood samples were collected in summer and winter. Four physiological, fourteen haematological, sixteen biochemical parameters as well as serum cortisol levels were analysed. Heart rate, respiratory rate, pulse and rectal temperature were increased in summer in comparison to winter. Values of heart rate proved significant at < 0.05. The results of blood haematology and biochemistry of the ponies revealed that there was no significant variation between summer and winter in most of the haematological and biochemical parameters, while there was a slight significant difference in leucocyte counts, monocytes, MCH, MPVK, platelets and AST activity. There were significant differences in serum cortisol concentration regarding season and age but not regarding gender.
设得兰矮种马原产于世界上最恶劣的环境——大西洋北部的岛屿，如今是最受欢迎的矮种马品种，分布在世界几乎每个角落。在兽医临床中广泛使用的生理、生化和血液学值的参考范围可能因季节、年龄、性别、饲养类型和所在地区的环境情况而有所不同。关于设得兰矮种马血液学和生化值的参考范围很少见。因此，本研究旨在评估季节、年龄和性别对沙特阿拉伯健康矮种马某些血液学和生化值以及皮质醇水平的影响。该研究于2016年12月至2017年6月在沙特阿拉伯哈萨及其周边地区的矮种马上进行。本研究纳入了23匹不同年龄的临床健康雄性和雌性矮种马进行血液学和生化分析。对每只动物在夏季和冬季采集血样。分析了四项生理参数、十四项血液学参数、十六项生化参数以及血清皮质醇水平。与冬季相比，夏季的心率、呼吸频率、脉搏和直肠温度有所升高。心率值在<0.05时具有显著性。矮种马的血液血液学和生化结果显示，大多数血液学和生化参数在夏季和冬季之间没有显著差异，而白细胞计数、单核细胞、平均红细胞血红蛋白含量、平均血小板体积、血小板和天冬氨酸转氨酶活性略有显著差异。血清皮质醇浓度在季节和年龄方面存在显著差异，但在性别方面没有显著差异。
