From: Proteomic landscape of seminal plasma associated with dairy bull fertility
A graphical abstract showing the main findings of this study. Using DDA label-free mass spectrometry, 1,159 proteins were identified in dairy bull seminal plasma. Of the 1,159 proteins, 949 were found in seminal plasma from high fertility (HF, n = 5) bulls and 771 proteins in low fertility (LF, n = 5) sires. while 561 proteins were common to both HF and LF phenotypes. There were 50 and 29 seminal proteins more abundant in HF and LF bulls, respectively. Based on multivariate analyses, there were eight proteins with VIP score greater than 1.5 (Fig. 4b), indicating meaningful contributions of such proteins for definition of the fertility phenotype. Among them, four proteins were more abundant in either HF or LF bulls. DDA: dependent data acquired; PLS: partial least square; VIP: variable influence in projection.
