Fig. 1From: Association between sow and piglet blood hemoglobin concentrations and stillbirth riskCorrelation between blood hemoglobin concentration (HbC) in sows and piglets at farrowing (Note: each sow corresponded to 2 to 9 piglets) (correlation coefficient, r = 0.24). The association was tested on a linear mixed model [Intercept = 82.80, estimate for sow HbC (g/L) = 0.39 (P = 0.058)]Back to article page
