Your results
Plan fresh forage tonnage from dry-matter demand and feeding losses.
Calculated outcomes
- Total Dry Matter Kg
- 90,000 kg
Assumptions and estimates
- Method: Total dry matter = animals × daily forage DM × days. Fresh tonnes divide by dry-matter fraction and retained feeding fraction.
- Enter forage demand after accounting for other feed. This is a stock plan, not a balanced ration or animal-health recommendation.
