Is BMR sorghum silage a good replacement of corn silage?
Sorghum is a tropical grass grown primarily in semiarid and dry regions. It has become an important cereal crop because it is heat and drought tolerant. As forage, sorghum hybrids with the brown midrib (BMR) gene are becoming popular in the U.S. because their lower water requirement compared with corn. Average starch concentration in BMR sorghum silage is lower than in corn silage; however, fiber and fiber digestibility contents are very similar in these forages.
