Technical Abstract: Forage sorghum varieties have been developed to allow them to thrive under low moisture and poor soil conditions while producing adequate amounts of forage. In addition, newer varieties, such as the brown midrib (BMR) hybrids, can be alternatives to conventional varieties as they contain less lignin, resulting in improved ruminal fiber digestibility and potentially greater milk production. These forage sorghum varieties can be ensiled and used as a replacement for corn silage where environmental conditions do not support the production of corn for silage. This review looked at the research that has been conducted to evaluate BMR sorghum silage varieties compared to conventional sorghum silage varieties and conventional corn silage varieties. Varieties of BMR sorghum silage outperformed varieties of conventional sorghum silage, indicating that the improved fiber digestibility of the BMR varieties improves productivity. In addition, varieties of BMR sorghum silage performed similarly to varieties of convention corn silage, indicating that they can be partial replacements for corn silage, especially in regions where water availability is low and soil fertility is marginal.
