What is the functions of acidifiers?

Welche Funktion haben Säuerungsmittel?

  1. Reduce the pH value of gastric juice, promote the activation of digestive enzymes such as pepsin, and regulate the gastric emptying speed

The role of feed acidifier is due to its acidifying effect, that is, by lowering the pH value in the gastrointestinal tract, an optimal digestive environment can be maintained. Pepsin is rapidly activated when the pH of the stomach contents is 2.0. When the pH value increased to 4, the activation rate was slower. The suitable pH value of pepsin is 2.0 ~ 3.5. When the pH value was greater than 3.6, the activity decreased significantly. When the pH value is greater than 6.0. Inactivation of pepsin. Therefore, the pH of gastric contents affects the digestion of feed protein. Therefore, adding an acidifier not only activates the source of pepsin, but also directly stimulates the secretion of digestive enzymes.

2.Prevent feed mildew

By adding acidifiers to the feed, the reproduction of mold in the feed can be prevented or controlled. Keep the freshness of the feed, thereby improving the palatability of the feed and the utilization rate of nutrients. In addition, the effects of vaccines and antibiotics are reduced due to the influence of mycotoxins, leading to suppressed immune function. Therefore, the hygiene status of the feed will directly affect the production performance of the chicken. Adding an acidulant can reduce a host of problems caused by mycotoxins.

3.Alternative to antibiotics

Antimicrobial resistance of pathogenic bacteria has been widely concerned. Among them, there are a large number of drug-resistant E. coli strains. Antibiotics are not effective in treating E. coli infections. Therefore, the acidifier has attracted much attention as a non-toxic, side effect, and non-residual antibacterial and bactericidal additive. Studies have shown that acidifiers can regulate the balance of gastrointestinal microflora, especially reduce the infection of Escherichia coli.

4.Improve the biological utilization of calcium

Acidifiers can not only reduce the pH of gastrointestinal contents, but also chelate minerals such as calcium in the feed. Promote intestinal absorption of calcium and other mineral elements.

5.Anti-stress effect

Most research results show that acidifiers such as calcium formate, fumaric acid, and citric acid have obvious effects on maintaining the environment balance of the digestive tract of animals and preventing heat stress. The reason is that the acidifier can be oxidized into carbon dioxide and bicarbonate in the body, which can buffer the harm caused by the alkalinity of the blood and keep the pH of the blood in an appropriate range. Thereby avoiding or alleviating heat stress, maintaining good health, etc.

6. Improve the palatability of chicken feed

Adding calcium formate can improve feed palatability, provide energy, promote chicken growth, reduce fatty liver, increase blood phosphorus content, increase daily egg production and egg weight.

7. Environmental protection acidifier

Calcium formate, citric acid, fumaric acid, lactic acid and other organic acids are mainly used in the diet, and the appropriate addition amount is 1% to 2%. It can reduce harmful gases such as ammonia produced by intestinal microorganisms, improve the intestinal environment, and have the effects of anti-stress and enhancing immunity.

In summary, feed acidifiers can not only reduce the pH value of the gastrointestinal tract, but also activate the source of pepsin and stimulate the secretion of digestive enzymes. Improve the biological activity of feed and gastrointestinal tract, and have the functions of promoting growth, disease prevention and health care. Today, when food safety and human health are concerned, acidifiers are high-efficiency, pollution-free, and residue-free feed additives that promote growth and inhibit the growth and reproduction of pathogenic microorganisms, and meet the requirements of replacing antibiotics as growth promoters. It is a potential green environmental protection additive, and it is widely used in the aquaculture industry.
