Gestational variation in blood profiles of failed common bottlenose dolphin (Tursiops truncatus) pregnancies

Reproductive success is a critical component of the care of bottlenose dolphins (Tursiops truncatus) in managed care facilities and is vital in sustaining free-ranging dolphin populations. Despite well-established breeding programs with high reproductive success rates, pregnancy failures still occur in managed care just as they do in free ranging dolphin populations. Normal reference ranges for biochemistry and hematology variations during each stage of gestation during bottlenose dolphin pregnancy have been established. Subsequently, alterations in blood parameters were evaluated retrospectively on failed pregnancies, to assess which biomarkers could be measured as potential indicators of early pregnancy abnormalities. This dataset contains 263 archived blood samples from 1989-2017 from 21 failed pregnancies in 16 managed care dolphins. Identifying subtle changes allows earlier detection, diagnosis and treatment of maternal or fetal abnormalities to improve survivability and achieve a positive pregnancy outcome.繁殖成功率是圈养管理设施中宽吻海豚（Tursiops truncatus）管护工作的核心组成部分，同时对维持野生宽吻海豚种群的存续至关重要。尽管当前已建立成熟完善的繁育计划且繁殖成功率可观，但圈养环境下仍会出现妊娠失败的情况，这与野生种群的现状一致。目前学界已明确宽吻海豚妊娠期各阶段血液生化与血液学指标的正常参考范围。随后，研究人员对妊娠失败案例的血液参数变化进行了回顾性分析，旨在筛选可作为早期妊娠异常潜在检测指标的生物标志物。本数据集涵盖1989年至2017年间，来自16只圈养宽吻海豚的21例妊娠失败案例的263份存档血液样本。识别此类细微变化可实现对母体或胎儿异常的早期发现、诊断与干预，从而提升幼崽存活率并改善妊娠结局。
