Ultrasonography has become the method of choice for monitoring gestation in veterinary obstetric. We provided a chronological description of the development of the ovine conceptus between day 30th and 100th, based on 3 different ultrasonographic morphometric th th foetal parameters: CRL (Crown-rump length), BPD (Biparietal diameter) and TL (Tibia length) and compared these data with ones registered during foetal growth of vitrified/warmed IVP embryos transferred into recipients ewes. Our results showed a regular increasing of the CRL and BPD whereas TL showed a regular increasing trend from day 54th to 89th, when it starts a faster raise until 100th day. No significant differences were observed between the parameters of NM (natural mating) group and V/W (Vitrified/Warmed embryos) group. On the other hand we could highlight an increase of the gestation period in the vitrified/warmed group and the absence of spontaneous lambing in 35%. Newborns derived after transfer of IVP vitrified embryos did not show any macroscopical alterations as well as the control group. Newborns derived after transfer of IVP vitrified embryos did not show any macroscopical alterations as well as the control Group.
