| Probiotic strain identity |
Different strains can have different stability, target species, and functional profiles. |
Genus, species, strain code, deposit or identification information where available. |
| Viable count |
Determines the delivered probiotic level and cost per active unit. |
Declared CFU per gram, method of enumeration, COA result, and guarantee at manufacture or expiry. |
| Prebiotic active fraction |
Prebiotic value depends on the type and concentration of functional substrate. |
MOS, FOS, inulin, GOS, beta-glucans, fiber fraction, yeast derivative, or other active declaration. |
| Blend ratio |
Shows how much of the product is active material versus carrier or processing aid. |
Active composition, carrier declaration, inclusion guidance, and formulation rationale. |
| Carrier system |
Carrier affects flowability, dusting, moisture protection, compatibility, and dilution value. |
Carrier type, feed-grade declaration, allergen status, GMO status, and physical data. |
| Encapsulation or protection |
Protected products may improve heat stability, moisture resistance, shelf-life, and delivery to the gut. |
Protection technology, release profile, heat-stability data, and application recommendation. |
| Heat stability |
Important for pelleting, extrusion, expansion, conditioning, and storage in warm climates. |
Stability data under relevant processing conditions and expected CFU recovery after processing. |
| Moisture and water activity |
High moisture can reduce probiotic viability, cause caking, and shorten shelf-life. |
Moisture limit, water activity where available, packaging protection, and storage conditions. |
| Particle size and flowability |
Affects dosing accuracy, blend uniformity, segregation risk, and premix manufacturing. |
Sieve analysis, bulk density, flowability data, dusting information, and appearance. |
| Microbiological safety |
Critical for feed safety, customer approval, and export markets. |
Pathogen absence, Salmonella status, E. coli, coliforms, yeast and mold where relevant, and contaminant limits. |
| Compatibility |
Synbiotic components may be affected by acids, antibiotics where permitted, coccidiostats, minerals, enzymes, or heat. |
Compatibility guidance for acidifiers, enzymes, phytogenics, organic acids, coccidiostats, medications, minerals, and pelleting. |
| Regulatory suitability |
Permitted microorganisms, claims, and labeling rules differ by destination market. |
Feed-use declaration, strain authorization support, label wording guidance, and destination-market compliance documents. |
