Abstract

The objective of this project was to determine if sugar beets could be ensiled with hay or soybean meal with or without a liquid mold inhibitor and the impact on nutrient composition, pH, and aerobic stability. A 3 x 2 factorial experiment where hay (control; H) or sugar beets mixed with either hay (SBH) or soybean meal (SB) were ensiled at a rate of 50-50 (as fed) without the mold inhibitor. The mold inhibitor (T) was included to create three additional treatments- HT, SBT, and SBHT. All treatments decreased in pH over time (P < 0.01), with the lowest pH value being generated by the SB treatment. Concentrations of NDF increased between d 0 and d 90 for treatments SB and SBT (P ≤ 0.01) and increased between d 90 and d 180 for treatments H, HT, SBH, and SBHT (P ≤ 0.01). Concentrations of ADF also increased among all treatments (P ≤ 0.05). Concentrations of CP increased from d 0 to d 90 for HT and SB treatments (P ≤ 0.01), increased from d 90 to d 180 for the SBT treatment (P ≤ 0.02), increased from d 0 to d 180 for the SBH treatment (P ≤ 0.03), and decreased from d 90 to d 180 for the SB treatment (P ≤ 0.01). The data suggests that sugar beets may be ensiled with hay or soybean meal, with or without a liquid mold inhibitor, without negatively impacting nutrient quality or preservation characteristics of the ensiled mixture.
