Fig. 1From: Metabolomic fingerprinting of pig seminal plasma identifies in vivo fertility biomarkersCorrelations between pig seminal plasma-metabolites and in vivo fertility outcomes (farrowing rates, litter size, stillbirths per litter and gestion duration). Seminal plasma samples from entire ejaculates (24 ejaculates) of eight artificial insemination-boars (three ejaculates per boar) were used. Fertility parameters were recorded from 1,525 inseminations. The colour saturation of red to blue represents the correlation coefficients (R) between metabolites, from 1 to − 1, respectively. Significant correlations (P < 0.05) are marked with *Back to article page
