We hypothesized that during restriction, UBF and fetal and placentome measurements would be less than in adequately fed ewes, but upon realimentation, ewes would have similar UBF as ewes that were never restricted.
Because transplacental infection is possible only when the first placentome is present (30 days after conception in cattle), the window during which the infection of a bovine fetus might lead to a porencephaly/hydranencephaly-micromyelia-arthrogryposis syndrome ranges from 30 to 150 days after conception.
Breed, litter and parity effects on placental weight and placentome number, and consequences for the neonatal behaviour of the lamb.
25) recently described late gestation placentome morphometry in SCNT pregnancies complicated by hydroallantois, which may provide clues for the understanding of the pathophysiology of this abnormality during pregnancy.
We recently showed that among the fetuses of pregnant cows that were infected after the establishment of the first placentome, 28% were infected and that an arthrogryposis/ hydranencephaly syndrome follows if transplacental virus transmission occurs before fetuses are immunocompetent (6).
After dressing, gravid uterine tissue and fetuses were removed, followed by weighing of each placentome and amniotic fluid.
Maternal intake did not affect fetal or total placentome mass at day 75 in H or C groups; however, switching H ewes to C at d 50 increased placentome mass at day 75 (2).
On the basis of data from this pertinent subset, we found that -28% of the calves born to cows primo-infected after the first placentome developed (which permitted the virus to cross the placenta) were indeed infected.

Undernutrition during the first half of gestation increases the predominance of fetal tissue in late-gestation ovine placentomes.
However, in NT and IVF gestations, the cotyledons formation is impaired and the cotyledon-caruncle interactions fail in successfully form the placentomes, resulting in fewer and larger placentomes (BERTOLINI & ANDERSON, 2002; CHAVATTE-PALMER et al, 2012).
During third trimester (days 120 to 143 of gestation) only detection of placentomes was observed.
