We studied the adrenocortical and vagal tone response to a single ACTH challenge in lame (n = 9) vs nonlame (n = 9) cows. Cows were paired according to parity, days in milk, and milk yield. Plasma cortisol and dehydroepiandrosterone concentrations and cardiac vagal tone response (high-frequency component of heart rate variability) were compared after intravenous ACTH administration. Baseline, minimum/maximum, amplitude of the response and area under the response curve were compared. No difference could be detected between groups in the cortisol response. Dehydroepiandrosterone was irresponsive to ACTH treatment, and concentrations did not differ between lame and nonlame cows. Vagal tone decreased in response to the ACTH treatment. High freq...
