The economic value of sorghum:

Sorghum grains have high amylopectin content, moderate protein content, low fat content, and moderate amounts of tannin, ash, crude fiber and other substances. It is an important raw material for brewing liquor. As a brewing raw material, sorghum seeds can also be used to produce beer, vinegar and beverages. When sorghum grain is used as feed for livestock and poultry, its feeding value is similar to that of corn.

Since sorghum grains contain tannins, adding them to formula feed can effectively prevent pullorum in young livestock and poultry. The stems and leaves of sorghum can be used as green fodder or silage. The stalks of sweet sorghum can be used to make sugar and to produce ethanol, which can be used as a new type of fuel.
