Calcium Butyrate CAS 5743-36-2 (calcium salt of butyric acid) is a next-generation feed additive that delivers the short-chain fatty acid butyrate—the primary energy source for colonocytes and a key regulator of intestinal health—in a stable, non-volatile, and easy-to-handle powder form. Our calcium butyrate features minimum 98% purity with optimized particle engineering for uniform feed distribution, serving poultry integrators, swine producers, and aquaculture operations across 30+ countries seeking antibiotic-free growth promotion and gut integrity enhancement.
1. Targeted Colon Butyrate Release: Our calcium butyrate utilizes a proprietary lipid-microencapsulation technology (hydrogenated vegetable oil coating, melting point 58–62°C) that protects >85% of butyrate through the stomach and small intestine, achieving targeted release in the hindgut where butyrate exerts its maximum trophic effect on colonocytes. This represents a 3–4× improvement over unprotected calcium butyrate, which dissociates prematurely in the acidic gastric environment.
2. Gut Barrier Integrity Enhancement: In broiler chicken trials (n=2,400, 42-day grow-out), calcium butyrate at 500 g/tonne feed increased tight junction protein (occludin and claudin-3) expression by 2.3-fold versus control, reduced plasma endotoxin (LPS) levels by 38%, and decreased intestinal permeability (FITC-dextran assay) by 41%—confirming robust gut barrier strengthening.
3. Antimicrobial Alternative Performance: Across 5 commercial broiler trials (total n > 50,000 birds), our encapsulated calcium butyrate at 500 g/tonne matched or exceeded the performance of antibiotic growth promoters (AGPs: bacitracin methylene disalicylate 50 g/tonne): body weight +3.8%, FCR improved 5.2 points (1.62 vs. 1.67), and mortality reduced 28% versus non-supplemented control.
4. Odor-Controlled Handling: Unlike sodium butyrate and free butyric acid, our calcium butyrate has minimal volatile odor (<0.5 ppm butyric acid in headspace at 25°C), enabling safe manual handling and eliminating worker complaints at feed mill blending stations.

A top-5 Brazilian poultry integrator (processing 2.5M birds/week) adopted our encapsulated calcium butyrate at 500 g/tonne across all antibiotic-free (ABF) production contracts. Key outcomes vs. previous ABF program: average daily gain +4.2g/bird/day, FCR reduced from 1.68 to 1.61, footpad dermatitis incidence reduced from 12% to 4%, and processing plant condemnations down 31%. Annual ROI calculated at 3.8:1. “The consistency across different farms and seasons was remarkable—we use it across all ABF contracts now.” — Nutrition Director.
A Midwest US swine system (50,000 sows) implemented our calcium butyrate in nursery diets (Phase 1–3, 500–750 g/tonne) post-zinc oxide phase-out. Results: post-weaning diarrhea incidence reduced 52%, average wean-to-finish mortality improved from 5.2% to 3.9%, and nursery exit weight increased 0.8 kg/pig. The nutrition team calculated $1.85/pig net return after additive cost.
A Vietnamese intensive shrimp (Litopenaeus vannamei) farm added our calcium butyrate at 0.2% in commercial feed for a 90-day production cycle. Outcomes: survival rate increased from 72% to 86%, FCR improved from 1.45 to 1.32, and Vibrio parahaemolyticus (EMS/AHPND) incidence reduced from 18% to 3% across 12 ponds. “The hepatopancreas health improvement was visible—stronger color, better lipid content, more consistent molting.” — Farm Technical Manager.
