- Least squares means of cortisol concentration patterns (mean, baseline, pulse frequency, pulse amplitude, and pulse duration) in blood samples collected at 15-min intervals between 1000 and 1600 h for postpartum, anovular, suckled cows exposed to bulls (EB) and cows exposed to steers (ES) from D 2 through D 8 of a 9-d exposure period. D 0 = Start of the experiment; cows were 67 +/- 3.5 d postpartum.
- aSEM = Standard error of the mean.
