Maternal recognition of pregnancy (MRP) in cattle requires secretion of sufficient interferon tau (IFNT) by the conceptus to prevent luteolysis. However, recent evidence suggests that additional conceptus-derived products may be involved. The aim of this experiment was to identify conceptus-derived proteins in uterine luminal fluid (ULF) during MRP. Following estrous synchronization, the protein content of ULF from cyclic (n=4) and confirmed pregnant (n=4) he...

Intensive selection for milk production has led to a reduced reproduction efficiency of high-producing dairy cattle. The first month of pregnancy is associated to a high rate of pregnancy failures. In addition to embryo losses, pre-conceptional status of pregnant females has been reported to affect progeny performance after birth. This study aimed to investigate the impact of the conceptus on endometrium physiology and on peripheral blood leucocytes (PBL) gene expression patte...
