1Least square means were calculated from transformed data and then back-transformed for presentation of data.
2Sows received their daily gestation ration once at 0730 a.m.
3Sows received their daily gestation ration once at 1130 a.m.
4Sows received their daily gestation ration once at 1530 p.m.
5Total FAA was the sum of every 15 min feeding activity 1-hr preprandial.
6Total area under the curve (AUC) was calculated using the trapezoidal summation method.
a–cLeast square means within a row with uncommon superscript letters significantly differ (P < 0.05; Tukey–Kramer adjusted).
