Not every gut health product works the same way, and most address only one side of the equation. ActiMax+ pairs mannan and β-glucan protection with multi-strain Bacillus to support both a more stable rumen environment and multi-barrier protection against pathogens.
Designed for ruminants, ActiMax+ combines a high concentration of live probiotic yeast with four heat-stable Bacillus strains built to withstand pelleting and gastric passage. Together, these technologies support fiber digestion, help reduce lactic acid buildup, and promote consistency through weaning, ration changes, and heat stress.

Two Technologies. Stronger Gut Support.
Live probiotic yeast and four complementary Bacillus strains work together to support stable rumen fermentation, nutrient digestibility, and multi-barrier gut protection.
Why It's Different

Dual-Action Gut Technology
ActiMax+ combines live-cell yeast with four heat-stable Bacillus strains to support microbial balance and digestion through complementary modes of action.
Live yeast consumes oxygen, supporting anaerobic rumen conditions and stable rumen and hindgut pH.
Yeast cell-wall fractions (MOS and β-glucans) support pathogen and mycotoxin risk management and immune modulation.
Bacillus spores are designed to withstand pelleting and gastric passage.
Bacillus produces digestive enzymes, including amylase, protease, and cellulase, that support nutrient digestibility.
Together, both components contribute to direct pathogen inhibition, pathogen/toxin binding, and microbiome stabilization.
High-Potency Support for Rumen Performance
A 5-Gram Feeding Rate Delivers:
40 billion CFU of live-cell yeast
4 billion CFU of Bacillus across four strains
The live yeast’s oxygen-consuming action is associated with greater fiber digestion and volatile fatty acid (VFA) production, reduced lactic acid production, and improved animal performance and well-being. Complementary Bacillus activity supports nutrient utilization and gut protection.
