Formula or calculation method
Paddock count = rest days / grazing days + 1.
Acres per paddock = total acres / paddock count.
Forage supply is compared with animal-unit demand.
Worked example
Twenty acres split for a 30-day rest period and 3-day moves needs about 11 paddocks, or about 1.82 acres per paddock.
Practical planning tips
- Use local extension guidance when possible.
- Watch animal condition, heat, weather, forage quality, and water access.
- Add reserve for stress, lactation, illness, waste, and drought.
Common mistakes to avoid
- Ignoring rest periods and drought.
- Overestimating usable forage.
- Leaving no sacrifice area or backup feed plan.
