Protect purchased or harvested dry hay from ground moisture, rain, mould and untracked losses.
- 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
- Hay moisture meter and lot sheet
- Gloves and safe bale-handling equipment
Output and operating conditions
For horse-quality large round hay bales, ≤15% moisture is a documented storage benchmark. Requirements vary with bale size and preservative use.
Storage management, not a hay baler design. Original small-store layout must suit actual bale size, access and fire rules.Parts, quantities and dimensions
| Part | Quantity | Specification / dimensions |
|---|---|---|
| Dry ventilated storage area | 1 | Use a weatherproof shed where available; preserve access and fire separation. |
| Rated clean pallets or drained base | as measured | Keep bales off damp ground; use stable equipment suited to bale mass, without exposed animal-accessible nails. |
| Hay moisture meter and lot tags | 1 set | A probe designed for hay; follow bale-specific sampling instructions and record deliveries. |
Preparation and component checks
- Check storage capacity, load limits and local fire requirements.
- Arrange safe handling for heavy bales; do not lift them manually.
Procedure
- 1
Measure incoming bales, identify species and lot, and inspect a representative bale internally.
- 2
Measure moisture and separate damp, suspect or damaged hay before ordinary dry storage.
- 3
Prepare a clean drained base and roof cover; avoid direct ground contact and unsafe stacking.
- 4
Arrange stable lots with inspection access and ventilation; do not force all bale types into one stacking pattern.
- 5
Label dates and quantities and use older sound lots first while checking every feeding.
- 6
Log discarded material and adjust storage, purchasing and feeding practices to reduce recurring losses.
Ready-to-use checklist
- Hay is sound and appropriate for the intended animal.
- Storage remains dry, stable and accessible.
Safety and inspection
Do not feed mouldy hay to horses. Hot or smoking stacks can ignite when disturbed; keep people away and call emergency services. Do not seal damp hay in ordinary storage boxes.
Verify the result
Measure moisture with a suitable calibrated meter and representative samples. Colour or an outer dry layer cannot establish the inside condition.
Measurement log
- Mass, moisture, delivery and use dates per lot.
- Spoilage, heating and discarded quantities.
Maintenance and repeat checks
- Inspect after rain, roof leaks or humid spells and check new hay for heating as advised locally.
- Keep rodents, ignition sources and vehicle exhaust away; repair roof and base defects promptly.
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.
