ABSTRACT
Simmental cows in the third trimester of gestation wae used in 2 trials to determine the effects of time-restricted access to large round bales on cow performance and hay disappearance. In trial 1, high-quality (127 relative feed value) hay was fed ad libitum (no time restriction) or access-restricted to 9, 6, or 3 h/d. In trial 2, average-quality (96 relative feed value) hay was fed ad libitum or access-restricted to 9 or 6 h/d. In both trials, 72 cows were blocked by BW and assigned to 12 pens resulting in 6 cows per pen and 3 or 4 pens per treatment. Each pen had adequate bunk space for 7 cows, and time was limited by gates that prevented access to feeders. Results of trial 1 ...
