The first 4 weeks period of gestation is the most critical for nutrition, development, uterine spacing and implantation of the embryos to the uterus and the majority of prenatal losses occurs in pigs during this period. The aim of the present study was to describe the pig embryo (n=20) and its extra-embryonic membranes (amnion, chorion, allantois and yolk sac) at both macroscopic and microscopic level and determine those cells with endodermal origins. The pig fetal membranes were very similar to those of other domestic mammals. The allantois membrane was responsible for vascularizing the chorion. The yolk sac produced the first blood cells in the conceptus. The epithelial cells of the yolk sac, amnion and chorion originated from the endoderm.
