Figure 2.

Net mammary uptakes of ketogenic substrates (A) NEFA, (B) Triglycerides, (C) Acetate, and (D) Butyrate in the hours prior to and following the onset of farrowing in sows fed a control (CON; open circles) or fiber-supplemented (FIB; solid circle) diet during the last 2 wk of gestation. Acetate and butyrate were not analyzed for samples collected at 1, 3, 5, and 7 h relative to the onset of farrowing. The 0 h is the onset of farrowing. Pairwise comparison within hours relative to the onset of farrowing is indicated as a tendency (†P < 0.10) or significant change (*P < 0.05) when the treatment × hour interaction was significant.
