Lactobacillus acidophilus in livestock

As a feed additive,Lactobacillus acidophilus  can improve the intestinal ecology of animals and can be used for the preservation of feed. In recent years, the production of feed-grade Lactobacillus acidophilus has gradually increased.

Definition of Lactobacillus acidophilus

Lactobacillus acidophilus is a species of Lactobacillus. Its characteristics are: bacilli, rounded ends, immobile, no flagella, catalase negative, and amygdalin, cellobiose, escin, fructose, galactose, glucose, lactose, maltose, mannose, salicin , The sucrose reaction was negative, and the arabinose, gluconate, mannitol, melezitose, rhamnose, ribose, sorbose, and xylose reactions were negative. Lactobacillus acidophilus can produce some antibacterial substances during growth, such as organic acids, bacteriocins and bacteriocinoids, which can inhibit the growth and reproduction of harmful microorganisms in the intestinal tract and play a role in balancing the intestinal flora. And can produce B vitamins, including various folic acid, biotin, vitamin B6 and vitamin K, etc., secrete various beneficial substances, such as lactic acid, acetic acid, etc., and reduce intestinal pH.

The role of Lactobacillus acidophilus

1. Immunomodulatory function: Lactobacillus acidophilus can produce a large amount of immunoglobulins, thereby activating the body's immune cells, making it difficult for external bacteria to remain in the body, and achieve immune regulation.

2. Improve gastrointestinal function: Lactobacillus acidophilus forms a protective barrier on the surface of the intestinal mucosa to resist the invasion and damage of beneficial bacteria to the intestinal mucosa, and can produce acidic substances such as lactic acid and acetic acid, creating an environment that is not conducive to the growth of harmful bacteria. Inhibit the growth and reproduction of harmful bacteria, and play a role in regulating the intestinal flora.

3. Nutritional effect: Lactobacillus acidophilus can produce lactic acid and acetic acid after fermentation in the intestine, which can improve the utilization rate of high calcium, phosphorus and iron, promote the absorption of iron and vitamin D, produce vitamin K and vitamin B, and produce lactase Helps digest lactose.

4. Restore the intestinal tract damaged by the use of antibiotics: Antibiotics are an important factor causing intestinal flora imbalance. While antibiotics kill harmful bacteria, they also kill many beneficial bacteria. Timely supplementation of Lactobacillus acidophilus is very necessary to restore the balance of intestinal flora and improve nutrient absorption capacity.

Lactobacillus acidophilus detection index

Lactobacillus acidophilus is generally required to be a free-flowing powder, so the particle size index can be measured with a 0.25mm standard sieve. Of course, there must be no foreign matter in the product. The content of Lactobacillus acidophilus is a key testing item for its products. According to the requirements of a large number of standards, combined with the generation capabilities of enterprises. In terms of moisture index, it can be required not to be higher than 10.0%. For the health indicators of Lactobacillus acidophilus, we can detect indicators such as arsenic, lead, mercury, cadmium, coliform bacteria, total number of molds, aflatoxin B1, salmonella, and miscellaneous bacteria rate.
