yang product from lallemand animal nutrition mode of action

By modulating local immunity, and helping to limit colonization of the gut by undesirable bacteria, YANG helps maintain good digestive and barrier function and maintains performance during periods of stress.

Why it matters

Animals can experience stress due to high pathogen pressure, demanding production periods, or difficult environmental conditions. Stress can depress immunity and be detrimental to animal health and performance.

Targeted animal nutritional strategies can favorably affect physiological conditions and help reduce the impact of stress during challenging situations.


YANG is compatible with other feed ingredients and is stable in all animal feed types: mash, pellets, or liquids.

Shelf life

YANG can be kept for 24 months from the date of production when kept in its original unopened packaging in a cool and dry place.
