近年来，驴的数量急剧下降，许多品种目前被认为是濒危物种。与马相比，驴胎盘仍然没有完全研究。在马中，用于识别有流产或早产风险的妊娠马的诊断工具之一包括子宫及其内容物的经直肠超声检查;特别是子宫和胎盘的组合厚度（CUFF）。由于从未在驴中研究过CUPT，因此本研究旨在确定20只Martina弗兰卡珍妮妊娠后半期的经直肠CUFF值。还评价了马驹时间、马驹特征和胎盘大体外观以及测量值，结果值始终在正常范围内。与母马相似，在妊娠第6个月至12个月之间，CUFF持续显著增加，从妊娠第9个月至12个月，CUFF显著增加，尽管在统计学上无法评估，但从3只妊娠丢失的母马记录的CUFF值没有显示CUPT增加的证据。总之，提供了Martina弗兰卡驴妊娠第6至12个月的正常CUFF值，但需要进一步研究以确定可能的品种或体型CUFF特定差异，以及妊娠障碍或胎盘异常期间的CUFF值。(C)2016 Elsevier Inc.

In the recent years, the donkey population decreased dramatically so that many breeds are presently considered as endangered. In comparison to the horse, the donkey placenta still remains not completely studied. In the horse, one of the diagnostic tools useful to identify pregnant mares at risk of abortion or premature delivery, include the transrectal ultrasound examination of the uterus and its contents; and especially of the combined thickness of the uterus and of the placenta (CUFF). Since the CUPT was never investigated in donkeys, the present study was aimed to define the transrectal CUFF values during the last half of pregnancy in 20 Martina Franca jennies. Foalings times, foals characteristics and placental gross appearance, and measurements were also evaluated and values resulted always within normality. Differently to the mare, a continuous significant CUFF increase between the sixth to the 12 months of pregnancy, and a substantial increase from the ninth to the 12th month of pregnancy, was found. Although statistically not evaluable, the CUFF values recorded from three jennies with pregnancy loss did not show evidence of CUPT increases. In conclusion, normal CUFF values from the sixth to the 12th month of pregnancy in Martina Franca donkeys are provided, but further investigations are needed to define possible breed or body-size CUFF specific differences, as well as the CUFF values during pregnancy disturbances or placental abnormalities.
