Biological feature
Bacillus subtilis, known also as the hay bacillus or grass bacillus, it’s a member of bacillus, gram positive bacteria. One bacterium is 0.7-0.8um×2-3um, coloring evenly, without capsule, with flagella around it, can move. The size of spore is 0.6-0.9um×1.0-1.5um, oval or columnar, at central or a little near center of the bacterium; the bacterium will not expand after spore forms. The surface of the bacteria colony is rough and opaque, with the color of dirty white or yellow, usually form wrinkle pellicle during growing in the liquid culture medium. They are aerobic bacteria, can use protein, a variety of sugar and starch decompose tryptophan and form benzpyrole.
B. subtilis is rod-shaped, and has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions

1. Adjust effectively micro-ecology bacteria group balance in animal gut, restrain the growth of colibacillus, salmonella and other harmful bacteria and promote the growth of beneficial bacteria breeding, such as lactobacillus, bifidobacterium and etc.

2. It can control bacterial disease, protect against the gastrointestinal diseases like diarrhea etc.. reduce animal morbidity and the dosage of antibiotic.

3. Increase digestion utilization rate of feed, promote animal growth, reduce feed dosage and improve the feed efficiency.

4. Reduce excretion of ammonia and nitrogen in animal waste, decrease the concentration of harmful gas in breeding place for livestock and poultry, remove bad smell and flying, improve the breeding condition and reduce environment pollution.

5. Inhibit harmful mircroorganisms, promote the digestion and absorption, increase feed using, prevent animal from indigestion.

6. As the food of the animals. The beneficial bacteria colonies are the good food for the animals, including the rich active nutrients to promote the growth.

7. It can improve the animals’ immunity, strengthen their constitution, increase the survival rate and growing speed, and enhance the anti-stress ability, promote animals’ health.

8. Purify water, remove the mud, adjust and steady the water PH value   

Working Mechanism

This products compete with harmful bacterium for the attachment points in digestive tract,  produce antibacterial material, and compete with harmful bacteria to get nutrients, strive for oxygen by biological mechanisms ,thereby, establish normal microflora in digestive tract; adjust and improve immune function; improve digestion and absorption function; prevent toxic amine synthesized.

1.The active substances like subtilin, polymyxin, nystatin, gramicidin and etc. Generated during the growing period of bacillus subtilis, have obvious inhibiting function to pathogenic bacteria.

2. They can exhaust the free oxygen in the environment rapidly, make the intestinal tract hypoxia, promote the beneficial anaerobic bacteria growing, and generate the organic acid like lactic acid and etc., reduce the PH value of intestinal tract, inhibit the growth of other pathogenic bacteria indirectly.

3. They can stimulate the growth and development of the immune organ of animals, activate lymphocyte T, B, lift the level of immune protein and antibody, enhance the functions of cell immunity and humor immunity, and enhance the immunity of the group.

4. The bacillus subtilis can compound α-amylase, protease, lipase, cellulase and etc. by themselves, and play a role with digestive enzymes inside animals in the digestive tract.

5. They can compound several kinds of vitamin group B like vitamin, niacin and etc., enhance the activity of interferon and macrophage inside animals.


1. High spore content, stable performance, strong activity and long-lasting effect.

2. The consumption of free oxygen in the digestive tract and the creation of anaerobic environment are conducive to the growth of beneficial bacteria and the improvement of intestinal microecological environment. 

3. Refined and extracted by deep ventilation liquid fermentation process with high content of CFU, and no miscellaneous bacteria.

4. Good stability, such as anti-pepsin, acid-proof, salt-tolerant, heat-resistant and compression resistant; maintain high stability during feed granulating and the process of getting though the acidic condition in stomach.

5. Produced a variety of strong activity available enzymes by metabolism including protease, lipase,α-amylase, cellulase etc., which can effectively complement endogenous enzymes in intestinal tract, thereby, improve digestion and absorption of animals, promote animal growth.

6. Produce B vitamins such as B1, B2, B6, vitamin C and vitamin K2 during the growth and breeding of animals, which provides vitamin nutrition for animals.

7. Generate subtilin, polymyxin, short bacilli peptide etc. active substances in the process of growth, which can obvious inhibit pathogenic bacteria or endogenous infection conditioned pathogenic bacteria. Replace part of antibiotics, it is safe, green, non-toxic, no residue, non-corrosive, no compatibility taboo without pollution and side effects, harmless to animals.

8. This product is easy to use. With biodegradablity and ecological security, it has no negative effects to environment.
