Rotational Grazing & Rest, Rotate, Regrow

Rotational grazing divides a pasture into several paddocks and moves the herd through them one at a time. While one paddock is grazed the rest are resting and regrowing. This rest-and-recovery cycle keeps grass at its leafy, productive stage, lifts carrying capacity, and prevents the patchy overgrazing you get from leaving stock on the whole farm at once.

With one paddock grazed at a time, the other paddocks must rest while the herd works through them. Grazing days per paddock = rest days ÷ (paddocks − 1). For example a 30-day rest period across 7 paddocks gives 30 ÷ 6 = 5 grazing days in each paddock, so the herd spends about five days per cell before moving on.

The rotation cycle is the total time to graze every paddock once and return to the first — it equals the rest period plus the grazing days in the paddock being grazed. In the 7-paddock, 30-day-rest example the cycle is about 35 days, meaning each paddock is grazed roughly every five weeks and rests the rest of the time.

Paddock size = total pasture area ÷ number of paddocks. Splitting 21 ha into 7 paddocks gives 3 ha each. More paddocks mean smaller cells, shorter grazing periods, more even grazing and longer rest — but more fencing and water points. Fewer, larger paddocks are cheaper to set up but graze less evenly.

Match the rest to how fast pasture regrows: shorter in fast-growing spring (often 15–25 days) and longer in slow growth or drought (40–90+ days). The aim is to graze each paddock only when it has recovered to its target cover, so adjust the rest period through the season rather than holding it fixed.

More paddocks give shorter grazing periods and longer rest, which improves utilisation and regrowth. Many graziers run 7–30+ cells. As a guide, choose paddocks so each is grazed for no more than one to three days; with electric fencing you can subdivide further into daily breaks without permanent fences.

Grass grazed and then rested regrows from healthy leaf and root reserves, producing more total dry matter across the season than continuously grazed pasture that never recovers. More feed grown per hectare means the land carries more stock — that's why well-run rotations often lift carrying capacity well above set stocking.

Yes — the rotation maths is the same for any grazing livestock. Cattle, buffalo, sheep and goats all benefit from rest-and-recovery grazing; just set the rest period and paddock count to suit your pasture, herd size and how fast the grass grows on your land.

They are solid planning figures. Real grazing days shift with growth rate, weather, pasture quality and herd demand, so treat the rest period as a target you adjust by eye as paddocks recover faster or slower. Re-check cover regularly and lengthen or shorten the rotation as the season changes.
