propionic acid (CAS 79-09-4) used for in poultry
Feed Preservatives
Propionic acid (CAS 79-09-4) and its salts are the most commonly used antifungal agents in the feed industry, inhibiting the production of mycotoxins (such as aflatoxins) in feed. They are particularly suitable for high-moisture silage and grain feeds.
Nutritional Regulation in Ruminants
Propionic acid is one of the primary fermentation products in the rumen of ruminants (such as cattle and sheep). It serves as a direct energy source, promotes glucose synthesis, and increases milk yield and butterfat content.
Adding propionic acid (CAS 79-09-4) to feed regulates rumen fermentation patterns, reduces methane production (environmental benefit), and simultaneously improves feed utilization.
