Turn a nutritionist-reviewed feeding requirement into a stock, storage-loss and purchasing plan.
- 1Identify the crop, animal or stored material
- 2Measure the real site and available resources
- 3Keep dated quality and quantity records
- 4Adjust care; seek advice for uncertain results
Site and operating requirements
- Start with one labelled small batch. Confirm clean input water, crop identity, hygiene, species-specific feed advice and a disposal plan.
- Measure dry matter and all water, energy, labour and discard costs; fresh weight alone does not prove feed gain.
Tools and measuring equipment
- Scales, calculator and inventory sheet
- Lot labels and sample bags
Output and operating conditions
Purchased kg = animals × daily kg dry matter × days ÷ feed DM fraction ÷ usable fraction. This is inventory arithmetic, not a balanced ration.
Original arithmetic example: 10 animals ×1 kg DM ×30 days ÷0.90 ÷0.90 ≈370 kg purchased feed. The 1 kg is an assumed input, not a prescription.Parts, quantities and dimensions
| Part | Quantity | Specification / dimensions |
|---|---|---|
| Animal and reviewed feed requirement list | 1 | Group animals by species, body size, age and production stage; obtain appropriate daily DM inputs. |
| Feed scales and representative samples | 1 set | Measure actual pack mass; request feed DM and nutrient analysis for important lots. |
| Inventory sheet and storage labels | 1 set | Record kilograms, usable fraction, expiry, delivery lead time and storage space. |
Preparation and component checks
- Obtain a species-appropriate feeding target.
- Check storage and handling limits before bulk buying.
Procedure
- 1
List animal groups and the period to cover, including possible supply delays.
- 2
Obtain the daily reviewed dry-matter requirement and the share expected from each feed.
- 3
Count and weigh usable stock; separate spoiled or unsuitable material rather than counting it as feed.
- 4
Convert each feed from dry matter to as-fed mass using its measured DM fraction.
- 5
Include a realistic recorded loss allowance and delivery reserve; compare with usable storage capacity.
- 6
Schedule purchases, record daily withdrawals and update the forecast whenever animals, weather or feed quality change.
Ready-to-use checklist
- Units and DM percentages have been checked.
- Reserve plan covers delays without unreviewed diet changes.
Safety and inspection
Different species, ages, pregnancy and work require different diets. Do not replace hay with grain, straw or by-products kilogram-for-kilogram without a reviewed formulation.
Verify the result
Weigh actual bales or bags and use laboratory DM where available. Reconcile opening stock plus purchases minus use and waste.
Measurement log
- Daily use, waste, purchases and remaining stock.
- DM tests, forecast days remaining and supplier lead time.
Maintenance and repeat checks
- Reconcile inventory weekly and inspect lot quality at every use.
- Keep nutrition decisions separate from cost arithmetic; review alternatives before stock runs out.
Troubleshooting
- Mould, unusual deterioration or inconsistent batches
- Reject the affected material; inspect seed quality, hygiene, drainage, temperature and storage seals. Correct and repeat a small batch with an advisor.
