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 < 0.01) for cows fed SIL than cows fed HY or HMCS. In Exp. 2, BW gain was greater (P < 0.01) for cows fed SIL2 than cows fed HMCS2; however, no differences (P ≥ 0.17) were detected in milk production, subsequent AI conception, or overall pregnancy rates. The similar performance of gestating cows fed hay or high-moisture corn stover indicates high-moisture corn stover is a viable hay replacement. When fed to lactating cows, high-moisture corn stover could be fed as a replacement to corn silage with no effect on milk or reproduction. Overall, feeding high-moisture corn stover is a cost-saving strategy in both stages of production.
