Figure 1: Values of milk anti-p80 BVD Ab binding % from fresh milk with no Bronopol preservative pill (x-axis) compared to milk stored at room temperature for 7 days with preservative pill (y-axis) from the same cows. Correlation between combinations of 2 sample handling methods (there were 4 different sample handling methods) was always close to r = 0.65, the correlation shown here. The pattern was always evident that for low BVD Ab binding % values (higher anti-p80 BVD Ab in milk), there was a stronger relationship between differently handled milk samples than for high BVD Ab binding % values (higher anti-p80 BVD Ab in milk) as shown in the upper right corner.
