qPCR analysis of candidate genes in the endometrium significantly affected by day of the estrous cycle and early pregnancy. A-D Average calibrated, normalized relative expression values in arbitrary units (CNRQ ± SEM) determined by qPCR analysis of the endometrium from cyclic (black bars) and pregnant (open bars) heifers (n=5 per treatment per time-point) throughout the estrous cycle and early pregnancy.
