What Factors Increase Risk?Ĭyanogenic glucosides that can lead to prussic acid formation are found in the greatest concentration in the leaf portion of young, rapidly growing plants. The damage could be caused by frost and freezing, or anything else that leads to cell rupture such as crushing, trampling, chewing, or chopping. However, any factor that causes the plant cells to rupture and these compounds to combine can lead to prussic acid release. Under normal conditions these is no contact between these compounds and therefore no risk of poisoning. The enzymes that would trigger the prussic acid production and located in other plant tissues, specifically the leaf. Some plants, particularly sorghums and sudangrass, accumulate cyanogenic (prussic acid producing) glucosides in the outer tissue layers of the plant. Death often occurs within minutes of exposure. Ruminants are more susceptible because the rumen microbes have enzymes that release the prussic acid in the digestive tract. Prussic acid inhibits oxygen utilization by the animal at the cellular level resulting in suffocation. Prussic acid, also known as hydrocyanic acid or cyanide, is a rapidly acting, lethal toxin. What is Prussic Acid and How Does Poisoning Occur? Understanding how poisoning occurs and what factors are involved in contributing to those conditions will help producers take management steps to minimize their risk. Certain forage plants, especially sorghums and related species are associated with an increased risk of death loss because of prussic acid poisoning. 2.Written collaboratively by Ruth Beck, former SDSU Extension Agronomy Field Specialist, Warren Rusche, Assistant Professor SDSU Extension Feedlot Specialist and Sara Bauder SDSU Extension Agronomy Field Specialist.Īs the first frost date approaches, producers often have concerns about the risk of prussic acid poisoning in livestock.
