L-Isoleucine Feed Additive CAS 73-32-5 High Purity 98.5% Crystalline Powder for Compound Feed Formulation

• General Product Introduction:
• L‑Isoleucine is an indispensable branched‑chain essential amino acid which cannot be synthesized by animal organisms and must be supplemented via feed raw materials. This feed grade product is produced by microbial fermentation process, presented as white or off‑white crystalline powder with good free‑flowing property. It is widely applied in compound feed, premix and concentrate feed for swine, poultry, ruminants and aquatic species. L‑Isoleucine effectively balances dietary amino acid profile, improves feed utilization efficiency, supports muscle development and boosts animal growth performance. Suitable for feed manufacturers, premix factories and large‑scale breeding enterprises. Available in 25kg packaging and bulk shipment for global customers.

Quality Control:

1) Incoming Raw Material Inspection: All incoming raw materials undergo complete physical‑chemical testing before entering production lines; unqualified materials are rejected directly

1. 2) Whole‑process Production Monitoring: Key procedures including fermentation, crystallization, drying and pulverization are continuously monitored to stabilize product indicators
2. 3) Intermediate In‑process Sampling: Samples are collected at critical production nodes for real‑time testing of content, moisture and impurity parameters
3. 4) Finished Goods Full‑item Testing: Each production lot completes full‑index inspection covering appearance, assay, loss on drying, optical rotation, heavy metals and arsenic before release for shipment
4. 5) Full Batch Traceability System: Every batch is assigned unique batch number; production records and inspection reports can be fully traced
5. 6) Retention Sample Management: Representative samples from each shipment are reserved for a specified period for re‑examination if disputes occur
6. 7) Third‑party Inspection Acceptance: Accept authorized independent third‑party lab testing according to buyer's requirements
7. 8) Packaging Quality Check: Each package is checked for sealing integrity and label information correctness before warehouse outbound
