Sudan grass (Sorghum bicolor) is a warm season summer annual grass that is a member of the Sorghum family. It is grown for its use as a pasture grass, hay and silage for livestock. There are numerous varieties available and are known for the drought resistant abilities.

Toxic components
S. bicolor contains cyanogenic glycosides (chemicals which are able to convert to highly toxic hydrogen cyanide (HCN)) and nitrates. Horses grazing on S. bicolor are at risk of developing several different toxic syndromes: equine cystitis, ataxia syndrome, and cyanide poisoning.
