Abstract/OtherAbstract:
In this study, the period of pregnancy of nine collared peccary females has been monitored through the analysis of serum progesterone and estradiol-17β profiles. Serum concentrations of progesterone increased by Day 4 after conception, reaching concentrations of 33.4±5.6ng/mL on Day 10. Between Days 10 and 130 progesterone values were maintained between 20 and 60ng/mL. In the collared peccary, embryonic estradiol synthesis is first observed in the systemic circulation by Day 15 of pregnancy. Between Days 0 and 50 of pregnancy, average estradiol-17β concentrations were between 0 and 30pg/mL. From Day 75 of pregnancy onwards, estradiol concentrations were constantly increasing, reaching maximum concentrations (131.4±40.8pg/mL) on the day of parturition. The combined study of serum progesterone and estradiol-17β concentrations as a potential method for early pregnancy diagnosis presented the best overall accuracy (73%) when the threshold was established at 20ng/mL serum progesterone and 20pg/mL serum estradiol. Nevertheless, the accuracy for diagnosing pregnancy of females at mid and late pregnancy was 78% and 95%, respectively. The analysis of the sexual hormones during pregnancy could be a useful tool as a potential pregnancy diagnosis and an efficient predictor of the day of parturition in the captive collared peccary.
