GUSTOR N'RGY is a protected sodium butyrate feed additive developed by Norel to support gut health, nutrient utilization, and animal performance. Its patented technology protects sodium butyrate with palm fatty acid salts, allowing a gradual release throughout the gastrointestinal tract, where it promotes intestinal integrity, beneficial microbiota, and digestive efficiency. It is widely used in poultry, swine, aquaculture and ruminants, particularly in antibiotic-free production systems.
