In this episode, Adele Harty, former SDSU Extension Cow/Calf Field Specialist, talks with various cow/calf producers about the subject of nitrate testing feeds, and how that process is used in their day to day operations.

Prussic acid is a herbivory defense mechanism used by numerous plant species, but is most-associated with sorghum and sudangrass hybrids. While the risk of prussic acid poisoning is greatest in sorghum species, several additional species present across South Dakota can produce prussic acid at varying levels of concern.
