Essentially none in pure form. Comes as either a powder or granular product. Good under normal conditions of handling and storage. Sulfur is usually transported in bulk in a molten state and cooled to a solid upon reaching its destination. The overall long term supply picture for sulfur should be adequate.
Sulfur finds widely accepted use in ruminant diets.
Sulfur in this form is seldom used in monogastric feeds due to its low biological availability in monogastric nutrition. Only use oiled or treated sulfur. If sulfur is mixed or conveyed in pure or concentrated form, the explosive properties of sulfur dust must be considered. In normal feed mill use where the amount added to the feed is minor, there is generally little cause for concern. However, in premixing plants, where it may be conveyed or mixed in concentrated form, there is great cause for concern.
