In term of contribution to pregnancy, the mother not only produces oocytes but she also hosts the whole gestation, mainly in the uterus. For decades, a major focus has been made on oocyte and embryo quality in term of contribution to progression and issue of pregnancy in mammals, including cattle.

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...
