Histomorphometric and immunohistochemical analysis were carried out on 50 embryos and fetuses of the sheep and 50 red deer from the first prenatal stages until birth. To compare similar periods of gestation in both species, we calculate the percentages of gestation. The appearance of the abomasum was earlier in the red deer (22% gestation) than in the sheep (25% gestation). Throughout development the epithelium happened sequentially, being of the types pseudostratified to simple cylindrical. This important modification was earlier in the red deer than the sheep. At 46% gestation in red deer and 50% in sheep, gastric pits were observed on the surface of abomasal folds. Our studies suggest a close link between the initial formation of these pseudoglandular structures and the clear separation of lamina propria and submucosa separated by de muscularis mucosae.

Introduction
The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the fallow deer, and the chital; and the Capreolinae, including the reindeer (caribou), the roe deer, and the moose.
Deer are seasonally polyestrous animals that have multiple estrous cycles only during certain periods of the year, similar to horses, sheep, goats, and cats. A historic 1906 paper by Sakurai[1] characterised the prenatal development of the deer embryo (cervus capreolus). The average prenatal development period for deer (Mule) is 200 days.
Deer are typically a uniparental species, where the offspring (fawn) is only cared for by the mother (doe).
