Feed Formulation Notes
Species-Specific Dosage Guidelines
Poultry (Broilers/Layers): Optimizes protein efficiency, replaces expensive soybean meal, and supports early feather growth. (Typical inclusion rate: 0.1%–0.3% finished feed).
Swine (Nursery/Finisher): Balances first-limiting amino acid ratios to improve Average Daily Gain (ADG) and Lean Meat Percentage. (Typical inclusion rate: 0.15%–0.45% finished feed).
Aquaculture (Tilapia/Shrimp): Enhances muscle tissue synthesis in low-fishmeal diets.
Handling & Mixing Performance
Particle Size Distribution: Mesh size optimized (95% passing 20-60 mesh) for uniform dispersion in high-speed micro-ingredient feed mixers.
Hygroscopicity & Bulk Density: Low-dust crystalline form prevents caking under tropical storage conditions (Relative Humidity up to 75%).
Quality Compliance
Global Regulation
EU Feed Hygiene Standard (FAMI-QS): Certified batch-level traceability for all export lots.
US FDA Compliance: Registered facility, compliant with FSMA (Food Safety Modernization Act) rules.
ISO Standards: ISO 9001:2015 (Quality Management) and ISO 22000 (Feed Safety).
Kosher / Halal: Certificates available upon request for specific market needs.
