Potassium diformate is widely used as an additive in animal feed, particularly for swine and poultry, to improve growth performance and overall health. It acts as an acidifier in the digestive system, creating an environment that inhibits the growth of harmful bacteria such as Salmonella and E. coli. This helps reduce the risk of infections and promotes better nutrient absorption. Additionally, it enhances feed efficiency, leading to improved weight gain and reduced feed costs. Its antimicrobial properties also contribute to better gut health, making it a valuable component in animal nutrition. Furthermore, it is considered a safe and effective alternative to antibiotics, aligning with the growing demand for antibiotic-free animal production.
