Delving into Johnson Grass Toxicity
Johnson Grass (Sorghum halepense) is a resilient grass species with a global presence, notorious for its toxicity towards grazing animals, particularly under stressful conditions like drought or frost. This comprehensive overview explores the toxicity of Johnson Grass, its implications, and potential countermeasures.
Identifying Johnson Grass
Originating from the Mediterranean, Johnson Grass has proliferated worldwide due to its adaptability. A rapid grower, it can tower up to eight feet, flaunting broad foliage and substantial seed heads. Its distinguishing feature, however, is its inherent toxicity.
The Toxic Elements in Johnson Grass
The primary toxic agents in Johnson Grass are cyanogenic glycosides, specifically dhurrin. Upon plant damage or stress, these compounds degrade to release hydrogen cyanide or prussic acid, a lethal toxin.
Impact of Johnson Grass Toxicity on Livestock
Hydrogen cyanide disrupts the oxygen function in animal cells. Livestock ingesting hazardous amounts of Johnson Grass could display symptoms such as accelerated breathing, irregular heartbeat, excessive salivation, seizures, and in severe cases, death.
Influences on Johnson Grass Toxicity
The toxicity levels in Johnson Grass are influenced by various factors. These encompass plant stress due to environmental circumstances like drought or frost, plant maturity, and the part of the plant consumed.
Controlling Johnson Grass Toxicity
Effective management of Johnson Grass toxicity necessitates a comprehensive approach. This involves implementing grazing management strategies such as rotational grazing and avoiding grazing during high-risk periods like post-frost or during a drought.
