Rotational grazing · start here

Split the pasture. Move the herd. Let the rest recover.

That is the whole idea. The workbook below turns it into your acres, your herd, and a parts list you can actually order.

The rotation in three numbers

Rotational grazing is one idea: split the pasture into sections, keep the herd in one section at a time, and let every other section rest and regrow. Three numbers run the whole thing.

01(rest ÷ graze) + 1How many paddocks you need. If grass takes 30 days to regrow and you move the herd every 3 days, that is 11 — ten resting, one being grazed.
024 to 8How many you actually build. You do not fence eleven paddocks. You build a handful in permanent fence and split them with one reel of polybraid.
03HalfHow much grass you leave standing. Grass regrows from the leaf left behind. Graze it to the dirt and it takes two to three times longer to come back.

The workbook below turns those three into your acres, your herd, and a parts list you can order. It takes about a minute. Have ready: the acres you will graze, how many head, and roughly what they weigh.

What that looks like on the ground

Continuous grazing

A single pasture with the herd spread across all of it, grass grazed short and patchy throughout.

Everything grazed a little.
Nothing gets to recover.

Rotational grazing

The same pasture split into sections: the herd grazing one section on day 1, the others resting or regrown and ready.

One paddock grazed hard.
The rest regrowing, undisturbed.

The herd eats the same amount either way. The difference is that most of the pasture is left alone to regrow. More on the why in what actually changes on a working ranch.

    Your grazing plan

    Paddocks this rotation needs:
    Permanent divisions to build:
    Give them this much each move:
    Ground per division:
    Fence to step out each move:
    Total energized wire:
    Energizer size:

    Paddock count is the formula (rest ÷ graze) + 1. The rest are estimates sized from your acres and herd — a grazier can tighten them on the phone.

    Before you build: where is the water?

    Water is what usually limits paddock layout — more than fence, more than grass. If every paddock has to walk back to one tank, the herd carves a mud lane through the middle of your plan and undoes it.

    Piping water out to the divisions is often the highest-return money in the whole system, and buried line frequently qualifies for USDA cost-share. Sort this out before you buy fence, not after.

    You do not build every paddock in permanent fence
    
Permanent divisions with one of them subdivided by a reel of polybraid, the herd on the grazed strip and the rest of that division still standing.

    
Field note

    Build four to eight permanent divisions and subdivide them with one reel of polybraid. You get the grazing benefit of eleven paddocks from a handful of permanent divisions and a reel — for a fraction of the cost, and without locking in a layout before you know how your ground actually grazes.
    

    

    

    

    

    What the numbers mean
    

    

    

    Paddocks = (rest ÷ graze) + 1
    

    If grass needs 30 days to regrow and you move every 3 days, you need 11 paddocks — ten resting, one being grazed. That is the whole formula. The number looks alarming for daily moves, which is why the workbook splits it into permanent divisions plus temporary strips. Worked through properly in the complete guide.
    

    

    

    You do not build every paddock in permanent fence
    

    Build four to eight permanent divisions and subdivide them with one reel of polybraid. You get the grazing benefit of eleven paddocks from six paddocks and a reel — for a fraction of the cost, and without locking in a layout before you know how your ground actually grazes. See temporary vs permanent for where to draw the line.
    

    

    

    Take half, leave half
    

    The plan above allocates about double what the herd will actually eat, because they trample and foul some of it. Grass regrows from the leaf you leave standing, so a paddock grazed to the dirt takes two to three times longer to recover — which breaks the rest period and collapses the rotation by midsummer. The soil side of this is in grazing for soil health.
    

    

    

    


    

    Common questions
    

    

    

    I have never done this. Where do I actually start?
    

    Build the permanent divisions the workbook recommends, buy one reel and one roll of polybraid, and strip-graze a single division for a few weeks before doing anything else. You will learn more about your ground in a month of moving fence than in a winter of planning. The portable electric fence buyer's guide walks the first build end to end.
    

    

    

    How many cows per acre can I run with rotational grazing?
    

    Your grass decides that more than anything, which is why the workbook asks about pasture quality. Its estimate on average pasture (about 2,500 lb of forage per acre), 1,200 lb cows and a 30-day rest works out to roughly one cow per acre — the point where one pass through your paddocks takes about as long as the grass needs to regrow. Thin or drought-stressed ground is closer to half that; a strong stand closer to one and a half. Those are the workbook's estimates, not a promise. Put your own acres and head in above and it tells you whether your numbers pencil out.
    

    

    

    What if the workbook says I am overstocked?
    

    It means your acreage cannot feed that many head through the rest period you picked. Run fewer head, shorten the rest, or budget for supplemental feed. Finding this out in March is cheap; finding it out in August is not. Is your grazing system performing? covers the signs to watch for.
    

    

    

    Do I need to move them every single day?
    

    No. Every three days captures most of the benefit for a fraction of the labour. Daily moves give better pasture use and more even manure distribution, but an every-three-days rotation you actually stick to beats a daily one you abandon in July. Mob vs rotational covers where higher density starts paying.
    

    

    

    What fence do I need for rotational grazing?
    

    A permanent perimeter, four to eight permanent divisions, and one reel of polybraid on step-in posts to split those into strips. The temporary fence does the work; the permanent fence just keeps the herd in the right neighborhood. The parts list above is exactly that system, sized to your numbers. The portable electric fence buyer's guide walks the first build, and temporary vs permanent covers where to draw the line between the two.
    

    

    

    My fence is not holding. What do I check first?
    

    Grounding, nine times out of ten — not the energizer. Start with how to ground an electric fence, then work the voltmeter decision tree to find the drop in about fifteen minutes.
    

    

    

    

    

    Glossary
    

    PaddockA fenced section of pasture grazed as one unit before the herd moves on.
    

    Rest periodThe days a grazed paddock is left alone to regrow before animals return to it.
    

    PolybraidA braided fence conductor with metal strands woven through it, built to carry an electric charge along the fence line.
    

    JouleThe unit an energizer's output is rated in. A higher rating gives it more to work with, but the actual shock at any point on the fence also depends on fence length, load, and grounding — not the rating alone.
    

    

    

    Common mistakes
    

      

    • Overstocking — more head than the acreage and rest period can actually support.
      • 

    • Moving too fast for the grass to recover, which collapses the rest period by midsummer.
      • 

    • Skipping water planning — a rotation only works if every paddock has water reachable from it.
