VIP score analysis based on weighted coefficients of the OPLS-DA model used to rank the contribution of top 30 metabolites to the discrimination between estrus and early pregnancy groups. A Heat map showing VIP of metabolites between DP9 and DP0, B A heat map showing VIP of metabolites between DP12 and DP0, C A heat map showing VIP of metabolites between DP15 and DP0, D The overlap of metabolites between early pregnancy (DP9, DP12, DP15) and estrus (DP0)
