Fish oil and butyrate (FOB) feeding increased fecal butyrate in the distal colon relative to corn oil and butyrate (COB)-fed rats, but only when the rats were injected with saline (SAL). FOB-fed rats injected with SAL had higher distal fecal butyrate levels than all other groups. Data are means ± SEMs for 9–10 rats per diet per treatment group. Bars with different letters are significantly different (P < 0.02).
