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. Never done this before? Start with the complete rotational grazing guide.

Continuous grazing spreads the herd over one field so nothing recovers. Rotational grazing confines them to one paddock while the rest regrow. Continuous grazing Everything grazed a little. Nothing gets to recover. Rotational grazing day 1 resting resting ready One paddock grazed hard. The rest regrowing, undisturbed.
The herd eats the same amount either way. The difference is that five-sixths of the pasture is left alone to regrow. More on the why in what actually changes on a working ranch.

permanent divisions to actually build
50%
of the grass you leave behind
Four permanent divisions, subdivided daily by one reel of polybraid, give the effect of thirty paddocks. You do not build thirty paddocks. You build four and carry a reel. step the fence forward each morning permanent permanent permanent Solid lines = permanent fence, built once. Dashed line = one reel of polybraid, moved daily.
This is why the cost is measured in hundreds, not thousands. The temporary fence does the work; the permanent fence just keeps the herd in the right neighbourhood. Post spacing worked through in how many step-in posts do you need.

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 thirty 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.
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.
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.
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.
What about water? Water is what usually limits paddock layout — if every paddock walks back to one tank, the herd carves a mud lane and undoes the plan. Piping water out to the divisions is often the highest-return money in the system, and buried line frequently qualifies for USDA cost-share. Start with how water placement affects performance, the water systems collection and the EQIP funding guide.
