What forage crop poses a risk of prussic acid poisoning for grazing livestock?

• A. Alfalfa
• B. Winter wheat
• C. Tall fescue
• D. Sorghum stalks

Answer: (D)

Sorghum stalks can pose a risk of prussic acid poisoning for grazing livestock due to the production of cyanogenic compounds, which can convert into prussic acid (hydrocyanic acid) under certain conditions. This risk is particularly heightened in sorghum varieties and can occur when the plants are under stress, such as during drought or after a frost. Livestock consuming large amounts of wilted or young sorghum can be particularly at risk. Understanding the conditions that lead to the formation of prussic acid is crucial for managing grazing practices and ensuring livestock safety. Recognizing the signs of prussic acid poisoning, such as difficulty breathing or neurological symptoms, is equally important for effective livestock management when grazing on these types of forage.
