aMain effect of bismuth subsalicylate (P < 0.05).
bMain effect of dietary sulfur (P < 0.05).
cInteraction of bismuth subsalicylate and dietary sulfur (P < 0.05).
d–f Within a row, means without a common superscript differ (P < 0.05).
1Treatments were arranged in a 2 × 2 factorial design, with dietary sulfur at 0.12 (low sulfur) or 0.42 (high sulfur) % of diet DM, and bismuth subsalicylate at 0 (CON) or 0.5 (BSS) % of diet DM.
2Standard error of the mean, n = 4 observations per treatment.
3Daily intakes calculated as diet DM intake × fatty acid concentration of the diet.
4Daily outflows calculated as effluent DM outflow × fatty acid concentration of effluent.
