Butisorb Powder (Sodium Butyrate ≥98.5%)
98.5% sodium butyrate powder for premix applications.
Sodium butyrate ≥98.5% in fine powder form — chosen for homogeneous mixing in mash feeds and premixes where granule segregation is a concern.
Butisorb Powder is the high-purity powder grade of sodium butyrate — the most widely used butyrate source in animal nutrition and a cost-effective way to supply butyrate for gut health in swine, poultry, ruminants and aquaculture.
Butyrate is the primary energy source for colonocytes and a key signal for gut development and barrier function. SKF produces sodium butyrate from its own butyric acid, giving full control over quality from the molecule to the finished feed additive. The 98.5% powder grade is designed for premix applications where a fine, high-purity form is preferred.
Key Benefits
- ✓ High 98.5% purity powder for premix applications
