ORGANIC ACID

Some effects of organic acids and salts of organic acids in aquaculture. Organic acids and their salts used as feed additives in aquatic animals have been studied, especially when there are concerns about the transfer of pathogenic bacteria to humans from antibiotic resistant bacteria due to the use of antibiotics in animal feed at low doses.
Studies related to organic acids and aquatic animals today focus on the ability to enhance the absorption of phosphorus and other minerals. In addition, they also have other effects such as: Inhibiting the growth of harmful microorganisms (molds, yeasts, pathogenic bacteria) that exist in the environment, in food and in the body of aquatic animals; Improve growth, increase animal performance, and improve feed conversion ratio.

Effect on pathogenic bacteria and intestinal bacteria system of host
Acidification of fishmeal, feed ingredients and food can help control bacterial growth under storage conditions. Organic acids and blends in food processing can be beneficial as a Gut Environment Modifier (GEM). In feed ingredients or in the gut, organic acids like formic, benzoic and furamic acids inhibit bacterial growth.
Organic acid molecules penetrate the bacterial cell wall (especially gram-negative bacteria), dissociate in the cytoplasm and disrupt cellular functions. Therefore, when used in appropriate doses, the salt mix of these acids provides safety, efficacy and low cost in the control of gram-negative intestinal diseases, promoting bacterial flora. intestinal host.

Growth stimulating effect
So far, it has been shown that adding antibiotics to aquaculture feed has improved animal growth and feed conversion. However, recently there has been an increase in consumers and aquaculturists' awareness of responsible and sustainable aquaculture, as well as too much debate about products originating from Southeast Asia country. In addition, the EU has banned the use of all antibiotics in animal feed because the use of antibiotics in animal feed would be able to transfer antibiotic resistance genes to pathogenic bacteria. people and animals
Therefore, organic acids and their salts have been considered as feed additives (called non-antibiotics) to replace antibiotics.
In animal nutrition, their organic acids and salts are used to improve animal performance through different routes: food, gastrointestinal tract and thus affect metabolism. of animals.

In animal nutrition, organic acids and their salts are used to improve animal performance through different routes: food, gastrointestinal tract and thus affect animal metabolism.
In the gastrointestinal tract: the mechanism of action of organic acids in the digestive tract works in two ways: (1) reducing the pH in the stomach, especially in the small intestine, (2) dissociation in bacterial cells and the accumulation of salt anions inhibits the growth of gram-negative bacteria.
Table 1. Effects of organic acids and salts on animal nutrition.

In food: even in a hygienic environment, aquatic food can be affected by small amounts of mold, yeast and bacteria. Under appropriate conditions, these microorganisms grow rapidly, especially at high humidity (> 14%). These preservatives reduce the growth of microorganisms and thus reduce the risk of introducing pathogenic microorganisms into shrimp and fish. In addition, the acid eliminates bonds in feed ingredients and thus improves animal performance. The high protein content in the feed ensures a good growth rate for the young but also creates a high feed buffering and reduces the HCl acid in the stomach, resulting in the activation of pepsin and secretion of pancreatic juice. also reduces, making nutrient digestion restricted. The added organic acids reduce the buffering of the food and thus help improve feed digestion.
Bacteria such as Salmonella, E. coli are inhibited activity when pH <5, organic acids penetrate through bacterial cell membranes, dissociation in cytoplasm changes the activity of enzymes and metabolism of the cell, thereby inhibiting the growth of pathogenic microorganisms. Many studies have shown a decrease in the number of bacteria in the stomach and duodenum, while the beneficial strain, Lactobacillus, seems to tolerate an acidic environment and even grow in numbers.
In metabolism: organic acids and their salts are also considered as a source of energy in pet food.

Important organic acids are able to inhibit the growth of many species of Vibrio spp. causing shrimp diseases, especially Vibrio harveyi. Mainly short-chain organic acid group, including: Acetic acid, Butyric acid, Formic acid Propionic acid.
