Vascularization of broad ligament of uterus and its relationship with fetal and placental development in gilts

The objective of this study was to evaluate the influence of vascular architecture of broad ligament of the uterus on fetal and placental development in gilts. Fifteen gilts DB-90 (DanBred) were divided into three groups according to gestational age at slaughter (50, 80, and 106 days). After slaughter, fetuses and placentas were collected, weighed, and measured. The uterine arterial system was detached by latex repletion for quantification of the number and diameter of the terminal vessels in different regions of the uterine horns (apex, middle region, and base). Fetal and placental measurements were statistically analyzed and correlated with the number and diameter of arteries in each uterine segment. No correlation was observed (P > 0.10) between the number and diameter of arteries destined to the uterus with the number or weight of fetuses or placental weight in any gestational group. It was observed (P
