Combined Bacillus

Combined Bacillus Feed Grade

Combined Bacillus is a probiotic feed additive formulated by blending two or more Bacillus strains with complementary mechanisms of action. It is designed to provide synergistic benefits for gut health, disease resistance, and growth performance in livestock, poultry, and aquaculture species.

Specifically, Combined Bacillus typically contains strains such as Bacillus subtilis, Bacillus licheniformis, Bacillus coagulans, and Bacillus pumilus . Each strain contributes unique capabilities: B. subtilis and B. licheniformis are known for producing various digestive enzymes (protease, amylase, cellulase) and antimicrobial peptides , while different Bacillus species exhibit complementary antimicrobial activities against pathogens such as Clostridium perfringens. Studies have shown that multi-strain combinations can produce enhanced inhibitory effects compared to individual strains, with different Bacillus species providing synergistic protection through competitive exclusion, immune modulation, and intestinal barrier enhancement . The spore-forming nature of Bacillus strains ensures high stability during feed processing, storage, and gastrointestinal transit.

Combined Bacillus is carefully manufactured under strict quality control to maintain consistent viable cell counts, typically with a guaranteed minimum of ≥1×10⁹ CFU/g. The product is widely used in poultry, swine, ruminant, and aquaculture operations to support gut health, enhance disease resistance, improve feed efficiency, and promote overall production performance.
