The restriction or prohibition of antibiotic feed additives is a trend in progress. With the deepening of research in various fields, the abuse of antibiotics and feed drug additives in feed will bring harm to the breeding industry. At present, feed additive potassium diformate is widely used in large feed enterprises from the source to realize non resistant breeding feed additives.

After summarizing the existing data, the Scientific Committee on animal nutrition (scan) concluded that the primary reason why potassium diformate has become an acceptable alternative to antibiotics in the EU is its safety and antibacterial effect, based on its simple and unique molecular structure. Its main components, formic acid and potassium formate, are naturally present in nature or pig intestine, and finally (oxidized and metabolized in liver) are decomposed into carbon dioxide and water, which can be completely biodegraded. It can reduce the excretion of pathogenic bacteria, nitrogen and phosphorus in animals, and effectively purify the growth environment of animals.

In 2001, the EU approved potassium diformate as the first alternative antibiotic feed additive (Commission reg. (EC) No. 1334 / 2001); in 2005, China approved the use of potassium diformate in feed (nszz (2005) No. 03).

Potassium diformate is a derivative of the simplest organic acid. It has no structure similar to carcinogens and does not produce bacterial resistance. Toxicity test shows that the acute toxicity level of potassium diformate is very low, and the use of potassium dicarboxylate according to the instructions will not have any toxic effect on consumers and operators. Within the specified range of 0.6% - 1.8%, the only potassium diformate residue that can be detected in animal products is formate, and its amount in pig tissues will not produce toxicity; the only residue in animal excreta is formate, which will not cause environmental pollution. Formate concentration in edible tissue is very small, so it is also safe for livestock and poultry products consumers.

With the recognition of the harm of abusing antibiotics and bacterial resistance, the performance of potassium diformate is better than that of common compound acidifier, and it has become an ideal solution for the sustainable development of modern aquaculture.

By reducing the pH value of gastrointestinal tract, regulating the microflora structure of digestive tract, reducing the number of pathogenic bacteria such as Escherichia coli and Salmonella, inhibiting the reproduction of harmful bacteria, it is beneficial to the proliferation of beneficial bacteria, thus increasing the digestibility and absorption rate of energy and nutrients of animals, increasing the intake, improving the feed efficiency, reducing the consumption of intestinal maintenance of host, increasing the daily gain, and reducing the number of pathogenic bacteria Microbial metabolites and toxins are produced to reduce morbidity and mortality. Therefore, potassium diformate has a strong promoting effect on animal production performance, which is not significantly different from traditional antibiotics.

Compared with antibiotic growth promoters and other Acidifiers, feed additive potassium diformate is not only safe without side effects and residue, but also has a considerable and stable improvement in daily weight gain and feed reward of pigs. It can also be used in poultry and aquatic products.
