Feeding During Drought: Stretching Limited Hay Supplies Wisely
🌾 Introduction
Every hay producer knows the dangers of baling hay too wet — mold, heating, and spoilage. But what about hay that’s too dry?
Surprisingly, hay that’s over-dried before baling can cause nutrient loss, leaf shatter, and even reduced profit margins. Let’s explore how to strike the perfect moisture balance for safe, nutritious hay.
🌿 1. What Happens When Hay Dries Too Much
When hay moisture drops below 10%, the leaves — which hold most of the protein and nutrients — become brittle and break off easily during baling or handling.
The result:
- Loss of digestible nutrients
- More stem-heavy, less palatable hay
- Dusty feed that animals may reject
For alfalfa and clover, even small leaf losses can reduce protein by 3–5%.

💧 2. Ideal Moisture Ranges for Safe Baling
Getting the moisture level just right ensures safe storage and top-quality hay.
| Bale Type | Ideal Moisture | Too Dry | Too Wet |
|---|---|---|---|
| Small Square | 15–18% | <12% | >20% |
| Large Square | 12–16% | <10% | >18% |
| Round Bale | 10–15% | <8% | >16% |
Pro Tip: Always use a calibrated moisture tester before baling.

🌾 3. Why Over-Dry Hay Costs You Money
When hay becomes brittle, handling and transport cause leaf drop, leading to direct financial loss.
For example:
If 20% of your alfalfa’s leaves fall off due to dryness, you could lose $40–$60 per ton in value.
That’s money literally blowing away in the wind.
🌱 4. Techniques to Prevent Over-Drying
To avoid baling hay too dry, timing and technique matter.
Smart haymaking practices:
- Rake hay when it’s at 30–40% moisture — not fully dry.
- Bale during early morning or evening dew to retain leaf moisture.
- Use conditioners or tedders sparingly — they can over-dry thin windrows.
- Consider high-humidity baling systems that inject steam or mist to reduce shatter.

☀️ 5. Understanding the Weather Factor
Dry weather and low humidity speed up hay drying, but they also increase risk.
Monitor:
- Temperature: Above 85°F speeds evaporation.
- Humidity: Below 40% causes brittle stems.
- Wind speed: Over 10 mph accelerates moisture loss.
In arid regions, baling hay slightly earlier (with a bit of dew) can preserve nutritional quality.
🌾 6. Proper Storage for Dry Hay
Even overly dry hay can absorb moisture from humid air, causing mold or discoloration if stored improperly.
Best storage practices:
- Keep hay off the ground on pallets or gravel.
- Maintain good airflow in barns.
- Avoid stacking against walls — leave 6–12 inches of space.
