Figure 7.
White blood cell counts in newly weaned heifers injected repeatedly with saline (CTL−), increasing doses of LPS (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). (a and b) Cell counts of lymphocytes immediately before LPS challenge on hour 0, and at hours 1, 2, 4, and 8 post-challenge on day 0 (a) and day 10 (b). Effect of treatment × time on day 0 and day 10 (a, b; P < 0.01). (c and d) Cell counts of monocytes immediately before LPS challenge on hour 0, and at hours 1, 2, 4, and 8 post-challenge on day 0 (c) and day 10 (d). Effect of treatment × time on day 0 (c; P < 0.01). Effect of treatment × time on day 10 (d; P = 0.27). (e and f) Cell counts of neutrophils immediately before LPS challenge on hour 0, and at hours 1, 2, 4, and 8 post-challenge on day 0 (e) and day 10 (f). Effect of treatment × time on day 0 (e; P = 0.04). Effect of treatment × time on day 10 (f; P = 0.07). Error bars denote SEM.
