Calcium butyrate is one option within a broader butyrate and gut-health portfolio. For Latin American feed importers, qualifying a 98% powder or granule requires more than checking the assay: physical handling, mixing, packaging and the intended species all matter.
Confirm the exact commercial grade
Winstar Ingredients supplies feed-grade calcium butyrate 98% in powder and granule forms. The documented specification lists a white powder or white granules, assay of at least 98.0%, pH of 7.0–10.0 in the stated test solution, loss on drying of no more than 5.0%, heavy metals as lead of no more than 10 ppm and arsenic of no more than 2 ppm. The current approved specification and batch COA govern the order.
Coated and uncoated variants should be quoted only after the coating material, active content, particle size and release information are confirmed. Buyers should not assume that different forms are directly interchangeable.
Evaluate handling in the buyer’s process
- Compare powder and granule flow in the intended premix or feed line.
- Review dust control, segregation risk and dosing accuracy.
- Confirm mixing order and uniform distribution at the target inclusion level.
- Test compatibility with other ingredients and the planned manufacturing process.
- Inspect storage conditions and protection from moisture after opening.
Review packing and logistics
Documented packing is a 25 kg PP woven bag with inner PE liner or a 700 kg jumbo bag with inner PE liner. Shelf life is listed as 24 months when stored unopened in a cool, dry place under the recommended conditions. Importers should confirm pallet configuration, container loading, warehouse humidity, handling equipment and local labeling before shipment.
Separate feed positioning from medical claims
Calcium butyrate is positioned as a feed ingredient supporting formulation and gut-health strategies. It should not be marketed as a treatment or as guaranteed disease prevention. Species-specific performance and permitted claims require appropriate technical evaluation and destination-market review.
Use a controlled qualification sequence
- Define species, life stage, feed format and objective.
- Review TDS, SDS and representative COA.
- Run a handling and mixing assessment.
- Conduct a controlled formulation and performance trial.
- Approve specification, packing and commercial acceptance criteria.
