A satisfactory first truck does not automatically prove that every future DORB delivery will be the same. Repeat purchasing needs a simple consistency process, especially when a feed mill is protecting formulation stability and customer confidence.
These seven checks help a buyer approve a repeat DORB order with clearer evidence.
1. Compare the new batch with the approved benchmark
Keep the specification and report from the first approved lot. Compare the next report against it parameter by parameter, rather than relying on a general statement that the material is “same quality”. Use agreed tolerances and investigate material movement before dispatch.
2. Match the report to the batch and dispatch
Confirm the report date, lot number and dispatch documents. Batch traceability makes it easier to resolve a question and helps the buyer avoid comparing an old certificate with a new consignment.
3. Read the parameter pattern, not only protein
Protein needs context. Fibre, moisture, ash, sand silica/AIA and physical condition can change the practical value of DORB. A batch should show a coherent quality pattern rather than one attractive figure hiding weaker indicators.
4. Check moisture before it becomes a storage issue
Controlled moisture matters at dispatch and during handling. Look for clumping, unusual warmth, a musty smell or signs of water exposure. Store the material on dry, elevated flooring with airflow and inspect more frequently in humid conditions.
5. Confirm appearance and smell against the approved lot
Physical checks are not a replacement for testing, but they are useful early signals. Compare colour, free-flowing texture, odour and grittiness. A sudden change should trigger a review before the material enters the production system.
6. Use a representative sampling routine
Sample from multiple bags and locations, combine carefully and retain a sealed counter-sample. A single handful from the top of a bag rarely represents the full truck. Write the date, lot and supplier on the retained sample.
7. Record the result and close the loop with the supplier
Maintain a brief batch register: date, lot, key values, receipt observations, test result and decision. Share a specific question quickly if there is a variation. Consistency improves when both parties work from the same evidence.
Repeat-order approval checklist
- Current batch report received and traceable
- Key parameters within agreed range
- Physical check acceptable
- Representative sample retained
- Commercial terms and dispatch schedule reconfirmed
- Nutritionist/formulation team informed of any material shift
RSPL positions quality confidence as a repeatable process: documentation, controlled parameters, practical inspection and clear communication. A repeat order should be approved because the evidence supports it—not merely because the previous delivery was acceptable.
