Objectives were to compare circulating progesterone (P4) profile and pregnancies per AI (P/AI) of two commercial intravaginal P4 devices (PRID-Delta(®) vs CIDR(®)). In Experiment 1, ovariectomized dairy cows (PRID-Delta, n=6 vs CIDR, n=6) were sampled throughout 7 days to measure circulating P4. In Experiment 2 (PRID-Delta, n=399 vs CIDR, n=375), ...

The objectives of this study were to investigate heterogeneity in the variance of and the association between milk yield (MY) and pregnancy outcome (PO) in dairy cows, formally separating the within-herd (i.e., cow-level residual effects) from the between-herd (i.e., herd-level random effects) components. Based on a recently developed extension to ...

During pregnancy, changes occur in the maternal calcium homeostasis to fulfill fetal demand. We hypothesized that the fibroblast growth factor 23 (FGF23) system and Wnt signaling pathway are important for normal skeletal development in the offspring. Circulating α-klotho, FGF23, sclerostin, and 25-hydroxyvitamin D (25(OH)D) at the fetal and maternal sides ...

Abstract Measurement of amniotic fluid (AF) lactate concentration in complicated pregnancies may provide information on the extent of fetal acidemia. However, normalisation for AF volume may be necessary by calculating the lactate:creatinine (L:C) ratio. We measured these AF parameters and compared them to arterial cord blood lactate in 28 term ...

INTRODUCTION: The weight of the placenta is a crude but useful proxy for its function in vivo. Accordingly extremes of placental weight are associated with adverse pregnancy outcomes while even normal variations in placental size may impact lifelong health. Centile charts of placental weight for gestational age and gender are used ...
