Organic acid is a feed additive that is good for animal health.
The ban on turbidity in the European Union and the growing global demand for drug-free poultry products have led poultry producers to consider using organic acid feed additives. They found that the benefits of organic acids far outweigh the growth of poultry and improve its feed conversion rate. It also reduces the risk of pathogen transmission to a lower level while improving food safety.
1. Antibacterial effect of organic acids
Organic acids inhibit the growth of pathogenic bacteria through a variety of putative physiological mechanisms. One of the most accepted mechanisms is the ability to block the transport of cell membranes by absorbing nutrients and discharging waste to the bacteria and their environment. In a relatively balanced state. After the organic acid enters the internal pathogen (cytoplasm) of the human pathogen, it is released from the higher pH environment in the daughter cytoplasm and then carries the protons (hydrogen ions). When more and more organic acids are absorbed into the pathogen, the hydrogen ion content in the cytoplasm increases, making the cytoplasm a low pH environment. Therefore, in order for a pathogenic bacteria to survive, it is necessary to remove hydrogen ions in the cytoplasm to maintain the neutral pH state of the cells. The removal of hydrogen ions is accomplished by active transport, which is a physiological activity that requires energy and eventually depletes the energy reserve of the bacteria. Therefore, it not only limits the ability of bacteria to reproduce or synthesize toxins, but can eventually lead to the death of pathogenic bacteria such as E. coli, Salmonella, Listeria and Campylobacter, all of which are sourced from humans. Related to sexual diseases. In addition to inhibiting the growth of pathogenic bacteria, organic acids promote the growth of lactic acid bacteria and bifidobacteria through the digestive system of poultry and other animals. These bacteria promote the intestinal health of animals by producing lactic acid, acetic acid, propionic acid and tyrosine. The organic acid can further inhibit the colonization and growth of pathogenic bacteria in the digestive tract of the animal.
2. Can be used as an excellent antibiotic substitute
In the past, poultry feed manufacturers have added organic acids to their feeds, but their use is very limited. The lack of widespread use of organic acids is largely due to limited experimental data, lack of understanding of their mode of action, and other misunderstandings. However, many poultry production companies are rethinking this simple technology as a means of improving animal health and food safety.
Many nutritionists in Europe and other areas where antibiotics are banned agree that organic acids can replace antibiotics used in poultry feed to promote animal growth. In addition to being able to maintain and improve the performance of poultry, studies have shown that organic acids can also improve meat quality, reduce the environmental impact of poultry production, and improve poultry welfare.
Additives containing multiple organic acids are better at promoting poultry performance than additives containing only one organic acid alone. This is because various organic acids enter the cytoplasm at the respective diffusion rates through the cell wall and cell membrane, and then these organic acids are decomposed at different rates and their respective pKa values ​​(proton dissociation constants). A ruthenium base and a free hydrogen ion are formed.
A precise control of LCD cell gap containing liquid crystal is critical to achieving the best display performance. Spherical particles used to control the thickness of the liquid crystal layer must meet stringent requirements such as precise particle size, tight particle size distribution, suitable hardness, and excellent resistance against heat, cold and chemicals.
