Reproductive performance and embryofetal development
LGA
UTERUS
The absolute number of implantation (number of live fetuses + number of dead fetuses + number of resorptions), resorption of embryos or fetuses in the uterus, live and dead fetuses was registered. The fetal and placental weigth (g) were mensured on a precision scale. Based on these data, we obtained: fetal viability (number of live fetuses × 100 / number of implantations), post-implantation loss rate [(number of implantations—number of resorptions) × 100 / number of implantations], resorption rate (number of resorptions X 100 / number of implantations), placental index (placental weight / fetal weight), placental efficiency (fetal weight / placental weight) and sex ratio (number of male fetuses/numbers of female fetuses).The classification of fetal weight according to gestational age (CFWGA). After collecting fetuses from the uterine horns, they were weighed, and according to the mean ± 1.7 × standard deviation (SD) of the body weights obtained in the control group, they were classified as adequate for gestational age (AGA), small for gestational age (SGA) and large for gestational age (LGA).
