Estimating Forage Needs for Cows – Vet Guide 2025 🌾🐄
Hello! I’m Dr Duncan Houston BVSc. Planning winter hay supplies? Here’s how to estimate forage needs per cow using straightforward, practical equations—then refine with Ask A Vet’s customized support to optimize herd nutrition and reduce waste in 2025.
1. Base Intake—2% of Body Weight
- Typical 1,000 lb cow consumes ~2% body weight in dry matter (DM): around 20 lb DM/day of high-quality hay.
- Poor-quality forage (<6% crude protein) yields ~1.5% BW (~15 lb DM/day).
- Better hay (≥8% CP) and pasture allow 20–25 lb DM/day.
2. Convert to As-Fed Weight
- 10% moisture → Daily as-fed intake = 20 lb ÷ 0.90 ≈ 22 lb/day per cow.
3. Account for Wastage
- Hay waste can reach ~15% under round bales.
- To ensure intake: 22 lb ÷ (1 – 0.15) ≈ 26 lb/day hay delivered.
4. Adjust for Production Stage
- Cows in late pregnancy or nursing may need more—add ~20% → ~30–35 lb/day delivered.
5. Example Calculation
- 1,000 lb cow → 20 lb DM/day
- 22 lb/day as-fed (10% moisture)
- +15% waste → 26 lb forage delivered
- +20% extra for lactation/gestation → ~31 lb/day
