Resumo: | The goal of this research was to determine the volumetric proportions of the structural components of the goat placenta throughout gestation. We used nine goats of nondefined breed, separated into groups A, B and C, with 90, 120 and 150 days of gestation, respectively. From each animal fragments of three placentomes were obtained, one removed from the base, another from the middle part and the other from the end of the gestational uterine horn. The fragments were fixed in Bouin solution and histologically processed according to the standard techniques and stained with hematoxilin-eosin. Microscopically, a 25-point circular grid (Zeiss KPL ocular 6.3x with 25 points) was randomly used across the placentome to determine the volumetric proportion of the maternal and fetal connective tissue, syncytium, trophoblastic epithelium and binucleate cells. An increase of volumetric proportion of the syncytium was found at the end of gestation and also a decrease of volumetric proportion of fetal connective tissue in the same period.
