Fig. 2From: Influence of genetics and the pre-vaccination blood transcriptome on the variability of antibody levels after vaccination against Mycoplasma hyopneumoniae in pigsCorrelations of M. hyo Ab levels with production traits. a Correlation matrix (Pearson correlation coefficients) of M. hyo Ab levels in sera at 21, 28, 35, and 118 dpv; BW at 40 and 118 dpv; and ADG from 0 to 40 dpv and 40 to 118 dpv. Color intensity and size of the circle are proportional to the correlation coefficients. Non-significant (p > 0.05) correlations are crossed out. b, c Principal component analysis (PCA) of M. hyo Ab levels in sera at 21, 28, 35, and 118 dpv for components b 1–2 and c 1–3Back to article page
