Rotational grazing is the practice of moving livestock between fenced paddocks on a regular schedule, letting the grazed areas recover while the animals move to fresh grass. Done right, it doubles pasture productivity, reduces parasites, and keeps animals healthier. Done wrong — or not at all — you get overgrazed bare dirt, parasite bloom, and skinny animals.
Why bother?
- Forage regrowth is fastest after a grazed plant has 21+ days to recover. Continuous grazing never lets grass recover.
- Parasite larvae on the pasture die after 21-30 days without a host. Moving animals breaks the life cycle.
- Manure distribution improves — rotational grazing spreads fertility instead of concentrating it near shelters and water.
- Pasture quality compounds year-over-year. Many rotators see 30-50% more carrying capacity within 3 years.
Small-acreage setup (5-40 acres)
You don't need miles of permanent fencing. Most homesteaders use:
- A permanent perimeter (barbed wire or high-tensile) around the whole pasture.
- Movable interior fencing — either polywire with tread-in posts (cheap, flexible) or temporary electric netting (better for sheep and goats).
- Portable water (troughs on skids, or a hose dragged between paddocks).
- Shade — movable shade shelter or a tree line in every paddock.
Paddock size calculation
For most small-acreage operators: paddocks should be sized so your animals eat the top 1/3 of the forage in 1-3 days.
Rough math: a 1000-lb cow eats about 30 lbs of dry matter per day. A pasture at 2500 lbs/acre dry matter can support that cow for 2-3 days on a 1/4 acre paddock (grazing only 30-40% of available forage).
For sheep or goats: 7-10 animals per cow-equivalent. Paddock sizes proportionally smaller.
Rotation schedule
- Graze period: 1-3 days per paddock. Shorter is better for grass health.
- Rest period: 21-45 days depending on season. Longer in summer heat or drought.
- Number of paddocks: rest period ÷ graze period + 1. If you graze 2 days and rest 30 days, you need 16 paddocks.
For a hobby-scale operation, 6-10 paddocks on 10-20 acres is typical. Fewer paddocks means longer graze periods, which reduces pasture quality benefits.
Season-by-season
- Spring: grass grows fast. Move animals every 1-2 days to keep up.
- Summer: growth slows in heat/drought. Extend rest to 35-45 days.
- Fall: stockpile grass for late-fall grazing — skip some paddocks to grow tall grass for November.
- Winter: feed hay on sacrifice paddocks (one or two that take the abuse). This concentrates manure where you want future fertility and spares the rest.
Common mistakes
- Paddocks too big. Animals graze selectively, leaving weedy forage behind. Better to under-paddock at first and adjust.
- Not enough rest. 14 days is too short in most Canadian climates. Err toward 30+.
- Not monitoring grass height. Move animals when pasture is grazed to 4-6" (for cattle) or 3-4" (for sheep/goats), not by the calendar.
- Poor water access. Animals that walk far for water don't graze efficiently. Water within 250 m of any grazing paddock.
FAQ
How long until I see improvement?
Soil and grass respond within one season. Full carrying-capacity gains take 2-3 years of consistent rotation.
Can I rotate with permanent fencing only?
Yes, but rotational grazing works best with 6+ paddocks. Permanent fencing for that many paddocks is expensive; most operators use electric polywire.
