FEED BASED ADDITIVESSOLUTIONS
BETTER ENVIRONMENT - Better nutrient digestibility – enzymes, phytogenic compounds, probiotics- Better water quality – activated charcoal, humic acid+
BETTER GUT HEALTH– acidifier, enzymes, phytogenic compounds, prebiotic, probiotic, toxin binder
BETTER IMMUNITY– all of the above
