How to calculate grazing days
This calculator finds how many grazing days available forage will support by dividing available forage by daily herd consumption.
How the calculation works
Grazing days = Available forage ÷ Daily herd use.
Example
6,000 lbs of forage with a herd using 300 lbs/day: 6,000÷300 = 20 days.

Pro Tips for Grazing Days
- Forage availability estimates should account for utilization rate (animals typically shouldn't graze a pasture down to bare ground) — factor in a realistic usable percentage.
- Recalculate as herd size or pasture conditions change through the grazing season.
Common Grazing Days Mistakes to Avoid
- Using total standing forage without discounting for the portion that should be left ungrazed for pasture health, which overstates true available grazing days.
