Calcium formate, molecular formula Ca(HCOO)2, molecular weight 130.0, appearance is white or slightly yellow powder or crystal, non-toxic, slightly bitter taste, insoluble in alcohol, soluble in water, and the aqueous solution is neutral. The solubility of calcium formate does not change much with increasing temperature. It is 16g/100g water at 0°C, 18.4g/100g water at 100°C, and decomposes at 400°C.

Calcium formate is added to the feed, and a small amount of formic acid will be released in the animal body, which will reduce the pH value of the gastrointestinal tract and have a buffering effect, which is conducive to the stability of the pH value in the gastrointestinal tract, thereby inhibiting the reproduction of harmful bacteria and promoting the growth of beneficial microorganisms. For example, the growth of Lactobacillus can cover the intestinal mucosa without the invasion of toxins, so as to control and reduce the occurrence of diarrhea and dysentery related to bacteria. The dosage is generally 0.6-1.5%. Calcium formate is used as an acidifying agent. Compared with citric acid, it will not deliquesce in the feed production process, has good fluidity, and has a neutral PH value, which will not cause equipment corrosion. It can prevent nutrients such as vitamins and amino acids from being Destruction is an ideal feed acidifier, which can completely replace citric acid, fumaric acid, etc.
