Item 4	CNF	CF	OE500F	OE1500F	MF 3	SEM 2	p-Value
							CNF vs. CF	OE Linear	OE No Linear
Mannitol (µg/mL)	33.0	22.1	27.6	25.5	25.7	1.54	<0.001	0.13	0.053
Lactulose (µg/mL)	3.79	17.4	20.3	16.1	19.0	1.91	<0.001	0.62	0.13
L/M	0.11	0.76	0.73	0.64	0.69	0.065	<0.001	0.19	0.77

¹ CNF, basal diet no fasted; CF, OE500F, OE1500F group, basal diet containing 0, 500 and 1500 ppm of olive pomace extract and fasted, respectively; MF, basal diet containing 100 ppm of monensin and fasted. ² SEM, standard error of the mean (n = 12). ³ Fasted treatments were not significantly different to MF treatment by Dunnett’s test at 5%. ⁴ L/M, lactulose:mannitol ratio.
