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...
