Influence of hay feeding method, supplement moisture, or access time on intake and waste by beef cows.

Experiments were performed to determine the effects of feeding method and hay processing (Experiment 1), energy supplement moisture content and feeding method (Experiment 2), and access time to hay (Experiment 3) on cow body weight (), dry matter intake (), and hay or energy supplement intake and waste. Experiment 1 was designed as a 4 × 4 Latin Square using 48 multiparous, late-gestating, Angus cows (626 kg initial BW). Cows were stratified by age and BW into four treatment groups ( = 12 cows/group); treatment groups were then initially assigned randomly to treatments in a sequence of preset Latin Square periods.
