Short summary
The aim of this work was to determine the effect of the pre-mating weight (PMW) and placental characteristics on the birth weight (BW). Although prior studies have determined a relationship between BW and placental characteristics, no existing work has determined a relationship between the PMW and BW. This is also the first study in which placental surface area is used as a factor for determining the relationship between placental characteristics and BW.
