The Sulphur Block has been designed for animals to assist with detoxifying Prussic Acid which is present in Sorghum; a group of plant species which under certain conditions can produce cyanide. Sorghum includes pasture, hay, and silage used for animal feed & forage. Hungry animals may consume forage too rapidly which can cause Prussic Acid toxicity or poisoning . As Sulphur is known to detoxify Prussic Acid, offering the Sulphur block (a combination of salt and sulphur) to animals when feeding, can help reduce the risk of poisoning. Additional to this, Sulphur is essential for rumen health and the formation of amino acids – the building blocks of protein. Sulphur is also a key nutrient for wool growth.
