1Least squares means were calculated from transformed data and then back transformed for presentation of data.
2Sows received their daily gestation ration once at 0730 hours.
3Sows daily gestation ration was split into 2 and each portion offered at 0730 and 1530 hours.
4 Sows daily gestation ration was split into 3 and each portion offered at 0730, 1130, and 1530 hours.
5Total FAA was recorded 1-hr preprandial for each feeding occasion.
6Feeding-related behavior outside of feeding anticipatory times.
7Total AUC was calculated using the trapezoidal summation method.
a–cLeast squares means within a row with uncommon superscript significantly differ (P < 0.05) (Tukey–Kramer adjusted).
