Pigs were weighed individually at the beginning and at the end of the experimental periods on days −7, 1 and 10 (see protocol in Appendix A: Supplementary
material). Rectal temperature was measured using a digital thermometer (Microlife
Corporation) on day −5 (baseline), and on days 1, 5 and 9 at 13:00 h (2 h after LPS1,
LPS3 and LPS5, respectively).
