Protein encoded for by these genes were detected in uterine luminal fluid during the period of conceptus elongation (Day 13) through to initiation of implantation (Day 19) by either nano LC MS/MS or iTraq analyses. Significance is set at P<0.05 (*), P<0.01 (**) or P<0.001 (***). – denotes no significant effect of a given treatment. ND = protein product not detected by either method.
