Grazing days and stocking-rate calculator
Estimate usable pasture dry matter and compare it with daily herd feed demand. Your assumptions are editable; results are planning estimates, not prescriptions.

What the calculation means
Usable forage = acres × forage dry matter yield × utilization × (1 − reserve). Daily demand = head × average liveweight × dry-matter intake fraction. Estimated days = usable forage ÷ daily demand. Acres required = daily demand × target days ÷ usable forage per acre.
Field measurements, forage quality, plant regrowth, terrain, seasonal climate and animal class change outcomes. Do not treat these numbers as an official local stocking-rate recommendation; consult Extension and a qualified grazing professional.
