Abstract
ABSTRACT The objectives of this study were to evaluate ensiled high-moisture corn stover as an alternative forage for beef cows. In Exp. 1, multiparous, gestating Simmental and Angus × Simmental cows (n = 96) were limit fed 1 of 3 treatments: (1) 60% high-moisture corn stover, 25% ground cornstalks, and 15% corn gluten feed (HMCS); (2) 60% corn silage, 25% ground cornstalks, and 15% corn gluten feed (SIL); or (3) 60% hay, 25% ground cornstalks, and 15% corn gluten feed (HY) from 108 ± 14 to 38 ± 14 d prepartum. In Exp. 2, lactating Simmental and Simmental × Angus cows (n = 79) were limit fed 1 of 2 treatments at calving: (1) 75% high-moisture corn stover and 25% dried distillers grains (HMCS2) or (2) 70% corn silage and 30% dried distillers grains (SIL2). Diets were limit fed to achieve NASEM (2016) requirements for maintenance and lactation. In Exp. 1, BW gain was greater (P
