Stomach: Bacillus licheniformis (kills harmful bacteria), Bacillus subtilis (produces digestive enzymes) 
The foregut: Lactic acid bacteria (inhibits harmful bacteria, protects beneficial bacteria) 
The hindgut: Clostridium butyricum (Prevent inflammation and restore secondary fermentation digesta of intestinal mucosa)
Clostridium butyricum can metabolize in the intestine to produce multi-nutrient components and increase the intestinal volatile fatty acid content.  
It can increase acidity of digesta and inhibit harmful bacteria.
In combination with Clostridium butyricum and its niche competition, it can stimulate intestinal peristalsis and promote the discharge of pathogenic microorganisms.
At the same time, it can regulate the expression of tight junction protein related transcription factors and villus cell proliferation related silver, and increase intestinal structural integrity.
Clostridium butyricum also promotes the abundance of other probiotics in the gut.  
In addition, the body of piglets can also immunologically recognize Clostridium butyricum, activate immune cells, enhance humoral immunity, and promote the improvement of immune silver.
In addition, Clostridium butyricum can be combined with prebiotics, other probiotics and enzyme preparations to increase its functionality and has a huge market potential.
