The development of feed-grade calcium formate can be regarded as a far-reaching additive. Most experiments have shown that adding 5% calcium formate to the piglet's diet reduces the pH in the stomach and jejunum. After the acidic chyme enters the small intestine, it secretes enterostatin by chemically stimulating the wall of the small intestine, which slows down the speed of gastric emptying and the movement of food in the intestine. The residence time of food in the stomach is prolonged, so that the food is fully mixed with saliva and gastric juice and other digestive juices, which is beneficial to the digestion and absorption of nutrients in the food.

Calcium formate can lower the pH value of the diet, increase gastrointestinal acidity and digestive enzyme activity. Promote the reproduction of lactic acid bacteria and inhibit the growth of E. coli and Staphylococcus. The addition of 0.7% and 1% calcium formate to 42-day-old pig diets reduced the pH of gastric contents from 4.5 to 4.2 and 3.5, respectively, and significantly reduced the number of gastric colon and rectal E. coli. At the same time, lactic acid bacteria and yeasts grow in large numbers, which can effectively prevent digestive disorders and diarrhea caused by bacterial infections.

According to experiments, adding 1%-2% calcium formate to the diet can increase the feed intake of piglets by 5.2%-19.8%, increase the daily gain of piglets by 9%-38.67%, and increase the feed conversion rate by 11%-15%. . And adding calcium formate is better than adding other organic acids. The main reason for adding calcium formate to promote growth is to form a good microbial flora in the digestive tract, which can reduce the destruction of nutrients in the gastrointestinal tract and the production of toxins, increase the synthesis of nutrients and protect the gastrointestinal tract.
