Plots of the timeline of uterine levels of pH (A–C), CO₂ (%) (D–F) and HCO₃⁻ (mMol) (G–I) at the three experimental conditions in three selected sows. Corresponding figures for the same animal are horizontally displayed. Lines are a continuous representation of a set of 120 individual measurements (1 dot was recorded every 5 s for 10 min).
