Evaluation of aglepristone and oxytocin on induction of parturition in guinea pig.

Background: Induction of parturition in guinea pigs appears to be essential because these animals have a higher rate of reproductive problems than rabbits and small rodents.

Objectives: Since aglepristone (AGL) is a competitive progesterone antagonist acting through binding to progesterone receptors while oxytocin (OT) is a powerful constituent of uterine smooth muscle, the aim of this study was to evaluate the clinical and ultrasonographic impacts of AGL and OT on guinea pig parturition induction.

Methods: In this study, guinea pigs were allocated into five groups; each included five animals on the 61st day of pregnancy.

Comparison of Cell-Free Fetal DNA Plasma Content Used to Sex Determination Between Three Trimesters of Pregnancy in Torkaman Pregnant Mare.

This investigation aimed to compare the cell-free fetal DNA (cffDNA) plasma present in three trimesters of pregnancy in Torkaman pregnant mare. Peripheral blood samples of 32 pregnant mares in three trimesters of pregnancy were collected in tubes containing ethylenediaminetetraacetic acid at three time points. Circulating cffDNA was extracted from 3 mL of maternal plasma.
