The function of calcium formate is mainly achieved through the formic acid it dissociates in the stomach environment, and its effects are similar to those of potassium diformate:
It lowers the pH value of the gastrointestinal tract, which helps activate pepsin, compensates for the insufficient secretion of digestive enzymes and hydrochloric acid in piglets’ stomachs, and improves feed nutrient digestibility. It inhibits the growth and reproduction of Escherichia coli and other pathogenic bacteria, while promoting the growth of beneficial bacteria (such as lactic acid bacteria). These beneficial bacteria cover the intestinal mucosa, preventing invasion by toxins produced by Escherichia coli, thus reducing diarrhea related to bacterial infections.
As an organic acid, formic acid acts as a chelating agent during digestion, enhancing the intestinal absorption of minerals.
