^a–cWithin a row, means without a common superscript differ (P < 0.05).

^x,yWithin a column, means for days 1–4 of each period without a common superscript differ (P < 0.05).

*Diets were offered in a paired choice as mash in two feeders with four feeding spaces each. Each pig had access to 0.5 feeding space if all pigs were eating simultaneously.

^†Feed preference of a test diet was expressed as percentage of sum of feed intake of test diet and its reference diet.

^‡A value < 50 means that pigs preferred the reference diet. The lower the value, the stronger the preference for the reference diet over the test diet. Preference of the reference diet (= 100 – Feed preference of test diet) was not shown.

^||Least-squares means based on nine pen observations of eight pigs per double-choice comparison.

^$For feed preference, an effect of paired diet comparison (P < 0.001) and interaction between paired diet comparison and period (P = 0.007) were observed.
