Average intravaginal temperature and average maximum temperature on °C, and hours experienced fever of newly weaned heifers injected repeatedly with saline (CTL−), increasing doses of LPS over a 10-d period (CTL+), or CTL+ plus fed the diet supplemented with a low (OBE-L; 0.04% of diet DM) or a high (OBE-H; 0.16% of diet DM) dose of an olive oil bioactive extract (OBE)

¹CTL− = control diet + saline injections; CTL+ = control diet + LPS injections; OBE-L = control diet + olive oil bioactive extract at 0.04% of the diet + LPS injection; OBE-H = control diet + olive oil bioactive extract at 0.16% of the diet + LPS injection.

²Results are expressed as least square means from 12 heifers per treatment.

³Rectal temperature ≥ 39.5 °C was considered febrile.
