Key specifications to contract
Crude protein is nitrogen content multiplied by a conversion factor (usually 6.25); it estimates total protein but says nothing about amino-acid quality or digestibility.
The amino-acid profile — and above all digestible lysine, methionine, threonine and tryptophan — is what protein ingredients are actually bought for in modern formulation.
Digestibility expresses the proportion of a nutrient the animal can actually absorb; it converts an analytical composition into a nutritional value.
Ash is the inorganic residue after complete combustion; it indicates total mineral content and, in protein meals, is a practical marker for bone, shell, sand or mineral adulteration.
Moisture is water content expressed as a percentage; it dilutes every other nutrient, drives mould and mycotoxin risk in storage, and is the single most disputed parameter in bulk feed trade.
Microbiological specifications control Salmonella, Enterobacteriaceae, moulds and yeasts, protecting animal health, plant hygiene and — for several species — the human food chain.
Each parameter is explained in the specification library — what it measures, how it is tested and what to verify.
Laboratory testing programme
| Test | Why buyers run it |
|---|---|
| Crude protein (Kjeldahl or Dumas) | Contractual value; confirm nitrogen factor and moisture basis |
| Amino-acid profile, digestible basis | The real formulation value; detects heat damage crude protein hides |
| Urease / KOH solubility / protein dispersibility index | Processing intensity proxy for soy and heat-treated proteins |
| Total and acid-insoluble ash | Bone, shell, soil and mineral dilution indicator |
| Salmonella and Enterobacteriaceae | Protein meals are the classic entry point for pathogens into a mill |
| Moisture and water activity | Storage stability and short-weight economics |
Storage, packaging, transport & handling
Typically 3–6 months from production when held below 12% moisture, under 30 °C and protected from condensation. Marine and rendered proteins require antioxidant treatment; remaining shelf life on arrival should be contractual.
- — Keep moisture below the contractual maximum and monitor water activity in humid climates
- — Store on ventilated, dry floors with clear separation from finished feed and medicated materials
- — Apply first-expiry-first-out rotation and record production dates at intake
- — Monitor bulk temperature — self-heating signals microbial or oxidative activity
- — Bulk vessel parcels for large-volume commodity meals
- — 1,000–1,250 kg bulk bags with certified lifting loops for intermediate volumes
- — 25–50 kg polypropylene bags with liner where humidity or long storage is expected
- — Verify hold or container cleanliness and prior-cargo history before loading
- — Use kraft lining and desiccant for ocean containers into humid discharge ports
- — Record transit time and temperature exposure — both consume usable shelf life
- — Avoid repeated pneumatic handling, which generates fines and heat
- — Segregate materials subject to species-specific regulatory restrictions
- — Draw and retain sealed samples at every transfer of custody
Procurement considerations
- —Contract digestible amino acids or a heat-damage proxy, not crude protein alone
- —Define moisture basis, tolerance band, reference method and umpire laboratory
- —Specify sampling plan and the party drawing samples at load and discharge
- —Require lot-specific certificates of analysis matched to cargo marks
- — GMP+ FSA / FAMI-QS feed safety scheme certification of the producing site
- — ISO/IEC 17025 accredited analysis for contractual and safety parameters
- — HACCP plan covering the specific material and process route
- — Codex Alimentarius Code of Practice on Good Animal Feeding
Typical risks & common mistakes
- — Over-processing reducing digestible lysine while crude protein appears compliant
- — Non-protein nitrogen adulteration in tight markets
- — Salmonella recontamination after processing, during storage or transport
- — Origin switches changing the contaminant and composition profile
- — Buying on headline protein and price per tonne rather than cost per unit of digestible lysine
- — Accepting typical-value sheets instead of lot certificates
- — Skipping retained samples, which removes any basis for a later claim

Frequently asked questions
What is FeedKind or Calysta?
Trade names for methanotrophic bacterial protein. FeedKind is a leading commercial SCP with commercial trials in salmon and shrimp.
Is SCP GMO?
Most commercial SCP uses non-GMO microbial strains and is accepted in EU-non-GMO supply chains. Confirm per supplier.
How do I contract SCP?
Typically multi-year offtake with capacity-linked pricing. FeedMatch Group brokers introductions to producers.
For commercial farm feed buyers
Buying single cell protein for a commercial farm
- Best for
- Commercial farms, integrators, distributors and feed buyers sourcing single cell protein and related feed, additives or nutrition supply on a recurring commercial scale — not pet food, hobby farms or backyard quantities.
- Animal species covered
- Broilers and layers, dairy and beef cattle, pigs, tilapia, salmon and shrimp, plus sheep and goats on request.
- Typical feed buyer needs
- A written specification, verified suppliers who can hold that specification, comparable pricing on the same delivery terms, documented quality (CoA, certifications) and a supply schedule that matches production.
- Bulk feed and recurring supply
- Most requests are bulk or big-bag volumes on monthly or quarterly contracts. Volume per delivery, storage capacity on farm and contract length change price more than the headline per-tonne quote.
- Feed additives and premix
- Premix, amino acids, minerals, vitamins, enzymes, organic acids, toxin binders and other additives can be quoted alongside compound feed or ingredients so one supplier comparison covers the whole ration.
- What affects feed cost
- Raw-material origin and specification, inclusion rates, freight and Incoterms, packaging, order volume, payment terms, currency and certification requirements. Landed cost, not ex-works price, decides the winner.
- RFQ checklist
- Species and production stage, tonnes per month, target specification, delivery port or farm location, packaging, required certifications, first delivery date and contract duration.
- Supplier matching process
- You define the requirement, FeedMatch structures the RFQ, sends it to relevant qualified suppliers, and returns comparable offers side by side so you can negotiate on equal terms.
- Buyer is not charged
- Farm buyers are not charged to submit a requirement, receive matched suppliers or compare quotes.
FeedMatch helps farm buyers compare feed suppliers, nutrition providers, additives suppliers and related solutions. FeedMatch is an intermediary and does not manufacture feed or provide financing directly.
