1Rumen evacuation occurred before feeding simulation; pair feeding; feeding 1 time at 0800 h.
2Rumen evacuation occurred after 7-d feeding simulation; feeding every 2 h, 12 times a day.
3E−, endophyte-free tall fescue seed.
4E+, endophyte-infected tall fescue seed; 10 µg ERV/kg BW/d.
4SEM, standard error of the means, n=4/treatment.
