Description
The majority of pregnancy loss in cattle occurs between days 8 and 16 of gestation coincident with the initiation of conceptus elongation and the onset of maternal recognition of pregnancy. Differences in conceptus lengths on the same day of gestation may be related to an inherent lack of developmental competency or may simply be a consequence of asynchrony with the maternal environment. The primary objective of this work was to characterize differential patterns of mRNA expression between short and long bovine conceptuses recovered on Day 15 of gestation.
