Study on Placentome at Different Stages of Pregnancy in Black Bengal Goat
Publication Date : 02/10/2016
Placentome, component of placenta is a vascular fetal organ composed of cotyledons on the chorioallantoic membrane attached to discrete caruncles on the uterine wall. It plays a crucial role during pregnancy like connecting the developing fetus to the uterine wall to facilitate nutrient uptake, waste elimination, and gas exchange via the mother's blood supply and then become obsolete. Proper placentation to ensure appropriate nutrient supply is a prior condition to have sound and healthy fetus. “Black Bengal Goat” is a most promising livestock resource of Bangladesh for mitigating the increasing demand of meat for rapidly growing people. Considering this situation an experiment was designed to study the morphological and histological condition of placentome of Black Bengal goats (Capra hircus) at three different stages of pregnancy (50, 60 and 90 days). Number, type, shape, and distribution of plcentome at three different pregnancy stage were considered parameter incase of morphological study where as the maternal and fetal connective tissue, epithelium trophoblast and syncytium were also observed for histological study. All of the considered parameters showed significant differences among different pregnancy stages.
