The Antillean manatee (Trichechus manatus manatus) can be found along the Brazilian northern and northeastern coasts. Previous studies on the clinical biochemistry of these animals were conducted in North America and the Caribbean, whereas little is known regarding these parameters in South American manatee populations. Accordingly, the objective of the present study was to examine the hematology and clinical biochemistry of T. manatus manatus of different sexes and environments in Northeast Brazil. Whole blood and serum samples were obtained from healthy individuals from different environments. The hemogram analysis was performed and the levels of blood biochemical components were determined using an automatized platform. The only statistically significant difference observed in the hemogram was a higher number of heterophils in manatees screened at the dry season of the year. Clinical biochemistry profiling revealed that free-ranging manatees presented lower levels of creatinine. Albumin was detected in higher concentrations in animals from rehabilitation captivity and amylase presented higher levels in manatees kept in acclimation captivity. Free-ranging manatees showed higher serum aspartate aminotransferase levels when compared to rehabilitation captivity manatees. These results can aid veterinarians and conservation professionals in the development of better captivity management procedures and in the clinical approach of manatees.

来自巴西东北部不同类型圈养和自由生活的安的列斯海牛 (Trichechus manatus manatus) 的血液学和临床生化特征

安的列斯海牛 (Trichechus manatus manatus) 可以在巴西北部和东北部海岸找到。之前对这些动物的临床生物化学的研究是在北美和加勒比地区进行的，而对南美海牛种群的这些参数知之甚少。因此，本研究的目的是检查巴西东北部不同性别和环境的 T. manatus manatus 的血液学和临床生物化学。全血和血清样本来自不同环境的健康个体。进行血象分析并使用自动化平台确定血液生化成分的水平。在血象中观察到的唯一统计显着差异是在一年中的旱季筛选的海牛中的嗜异性细胞数量更多。临床生化分析显示，自由放养的海牛的肌酐水平较低。在康复圈养的动物中检测到的白蛋白浓度更高，而在驯化圈养的海牛中，淀粉酶的含量更高。与康复圈养海牛相比，自由放养的海牛表现出更高的血清天冬氨酸转氨酶水平。这些结果可以帮助兽医和保护专业人员制定更好的圈养管理程序和海牛的临床方法。临床生化分析显示，自由放养的海牛的肌酐水平较低。在康复圈养的动物中检测到的白蛋白浓度更高，而在驯化圈养的海牛中，淀粉酶的含量更高。与康复圈养海牛相比，自由放养的海牛表现出更高的血清天冬氨酸转氨酶水平。这些结果可以帮助兽医和保护专业人员制定更好的圈养管理程序和海牛的临床方法。临床生化分析显示，自由放养的海牛的肌酐水平较低。在康复圈养的动物中检测到的白蛋白浓度更高，而在驯化圈养的海牛中，淀粉酶的含量更高。与康复圈养海牛相比，自由放养的海牛表现出更高的血清天冬氨酸转氨酶水平。这些结果可以帮助兽医和保护专业人员制定更好的圈养管理程序和海牛的临床方法。与康复圈养海牛相比，自由放养的海牛表现出更高的血清天冬氨酸转氨酶水平。这些结果可以帮助兽医和保护专业人员制定更好的圈养管理程序和海牛的临床方法。与康复圈养海牛相比，自由放养的海牛显示出更高的血清天冬氨酸转氨酶水平。这些结果可以帮助兽医和保护专业人员制定更好的圈养管理程序和海牛的临床方法。
