Correlations between net portal appearance of PYY and NPA of total SCFA in pigs fed WSD, AXD, and RSD.

(A) Correlation between net portal appearance of PYY and SCFA for each pig after consumption of WSD, AXD, or RSD, n = 6. Each point represents a correlation between net portal appearance of PYY and SCFA for a given pig on a specific diet (time points 0, 60, 180, and 300 min relative to first daily meal). (B) Correlation with first (♦) and second (◊) meals after consumption of WWG, WAF, or RAF, n = 6. Each point represents the average net portal appearance of PYY (pools 1–4 as described in the Materials and Methods) correlated to the net portal appearance of SCFA (pools 1–4) for each pig on each experimental diet. Inserts show the Pearson’s r correlation and the corresponding P-value. Solid line represent means for meal 1, and the dashed line represent means for meal 2.
