Description of post ‐implantation embryonic stages in European roe deer (Capreolus capreolus) after embryonic diapause

This study describes normal stages of embryonic development mainly based on the external morphological traits of 56 well‐preserved post‐implantation roe deer embryos and attempts to assign the embryos to certain development stages. Carnegie stages of human embryos were used as an orientation for staging roe deer embryos. We observed a considerable range of variation of embryonic stages investigated until the end of January. We found post‐implantation stages of embryonic development already at the end of December and foetuses at the end of January. Moreover, assigning the embryos to a particular stage of development allows the comparison between pairs of twins and triplets. We showed that twins and triplets were always at the same development level, despite the discrepancy in inter‐twin and inter‐triplet size.
