Paddock Division
Part of Animal Husbandry
Splitting your grazing land into managed paddocks is the physical foundation of rotational grazing. Good paddock design makes daily livestock management simple; bad design creates constant problems.
Why Divide at All
A single large pasture with free-roaming livestock is a recipe for degradation. Animals are selective grazers — they return to the same palatable patches while ignoring coarse growth elsewhere. Within one season, you get overgrazed bare spots next to rank, ungrazed tussocks. The overgrazed areas weaken and die. The ungrazed areas go to seed and become unpalatable.
Paddock division forces animals to graze an area uniformly before moving on, then gives that area time to recover. The smaller the paddock and the higher the animal density within it, the more evenly animals graze. This is the mechanical basis of all managed grazing systems.
Planning Your Layout
Before building a single fence, walk your entire property and map these features:
Critical Features to Map
- Water sources — streams, springs, ponds, wells
- Topography — hills, slopes, drainage patterns, flood zones
- Existing fences, walls, or hedgerows — anything you can incorporate
- Shade and shelter — tree lines, windbreaks, buildings
- Access points — gates, lanes, roads you use for moving animals or equipment
- Soil differences — wet bottomland vs. dry hillside behave differently
Design Principles
- Every paddock needs water access. This is non-negotiable. Either run a lane to a central water point or ensure each paddock has its own source.
- Make paddocks roughly equal in carrying capacity — not necessarily equal in size. A lush bottomland paddock can be smaller than a dry hillside paddock.
- Plan movement lanes. You need to move animals between paddocks without them trampling through others. A central lane running the length of your property with paddocks branching off both sides is the most efficient layout.
- Gate placement matters. Put gates in corners where animals naturally congregate, or at the paddock’s highest point so animals move downhill (they do this willingly).
- Minimize fence length. Square or rectangular paddocks use less fencing than long, narrow ones. A square paddock encloses the most area per unit of fence.
Common Paddock Layouts
Wagon Wheel (Pie Layout)
Best for properties with a central water source.
╱ P1 ╲
╱──────────╲
╱ P6 WATER P2 ╲
╲ (center) ╱
╲ P5 P3 ╱
╲ P4 ╱
- Paddocks radiate outward from a central water point
- Animals always have water access without crossing other paddocks
- Works well for 4-8 paddocks
- Disadvantage: triangular paddocks have corners where animals concentrate
Central Lane (Spine Layout)
Best for rectangular properties or those with a water line running through.
┌─────┬─────┬─────┬─────┐
│ P1 │ P2 │ P3 │ P4 │
├═════╪═════╪═════╪═════┤ ← Central lane with water
│ P5 │ P6 │ P7 │ P8 │
└─────┴─────┴─────┴─────┘
- Paddocks on both sides of a central lane
- Water trough in the lane, accessible from each paddock via gates
- Easy to move animals — open one gate, close another
- Most scalable layout; add more paddocks by extending the lane
Stream Division
Best when a stream crosses the property.
- Run fences perpendicular to the stream so each paddock includes a stream section
- Fence both stream banks with a hardened crossing point in each paddock
- Prevents streambank damage while ensuring water access
Sizing Your Paddocks
Paddock size depends on three variables: herd size, forage production, and desired grazing duration.
Quick Sizing Formula
Paddock size (acres) = (Number of animals x Daily intake in lbs) x Days per grazing period
─────────────────────────────────────────────────────────────────────
Available forage per acre (lbs) x Utilization rate (0.5-0.6)
Practical example: 10 cows eating 30 lbs/day each, 3-day grazing period, on pasture producing 2,000 lbs/acre of standing forage:
(10 x 30) x 3 = 900 = 0.9 acres per paddock
─────────────── ────
2000 x 0.5 1000
With 6 paddocks at 0.9 acres each, you need about 5.4 acres total for the grazing area.
Start Conservative
If you are unsure of your forage production, make paddocks larger than calculated and reduce grazing time. You can always subdivide a large paddock later, but repairing an overgrazed small paddock takes a full season.
Paddock Count Guidelines
| Number of Paddocks | Rest Period (3-day grazing) | Best For |
|---|---|---|
| 4 | 9 days | Minimum viable rotation; marginal results |
| 6 | 15 days | Acceptable for fast-growing spring pasture |
| 8 | 21 days | Good year-round rotation in temperate climates |
| 12 | 33 days | Excellent recovery; handles drought and slow growth |
| 16+ | 45+ days | Intensive management; best pasture health |
More paddocks always means longer rest periods and healthier pasture. The trade-off is more fencing material and more frequent moves.
Building Fences with Salvaged Materials
In a post-collapse scenario, manufactured fencing may be unavailable. Here are practical options ranked by durability and effort.
Fence Types Comparison
| Type | Materials | Lifespan | Labor | Best For |
|---|---|---|---|---|
| Post-and-rail | Wood posts, split rails | 10-20 years | High initial | Permanent perimeter |
| Wattle fence | Flexible branches (willow, hazel) | 3-5 years | Moderate | Interior divisions |
| Stone wall | Fieldstone | 50+ years | Very high | Rocky terrain (use found stone) |
| Living hedge | Thorny plants (hawthorn, osage orange) | Permanent | Low ongoing | Long-term boundary |
| Earth bank + ditch | Soil, sod | 10-30 years | High initial | Wet areas, cattle |
| Thorn brush barrier | Dead thorny branches | 1-2 years | Low | Temporary paddock |
Post-and-Rail Construction
- Cut posts from durable wood — black locust, cedar, or oak. Posts should be 6-7 feet long, 4-6 inches diameter.
- Set posts 2-3 feet deep, 8-10 feet apart. Tamp soil firmly around each post. For corner and gate posts, use bracing (diagonal support post).
- Split rails from straight-grained logs. Each rail should span 2-3 post intervals (16-30 feet). Notch posts to seat rails, or drill through and pin with wooden pegs.
- Height: 4 feet minimum for cattle, 4.5 feet for horses. Sheep and goats need tighter spacing between rails or added brush to prevent squeeze-through.
Wattle Fence (Quick Internal Division)
- Drive stakes 12-18 inches apart along your fence line. Stakes should be 4-5 feet tall, made from any straight hardwood.
- Weave flexible branches horizontally between stakes, alternating front-back with each row. Willow, hazel, and young birch work best.
- Pack tightly — push each row down firmly against the one below.
- Height: 3-4 feet is sufficient for most livestock when combined with training.
Train Animals to Fences
Animals that have never encountered internal fences will test them. When first dividing paddocks, keep animals in one paddock for 3-5 days until they accept the boundary. Starting with your strongest fence line helps establish respect.
Gates and Movement
Gates are the most used and most abused part of any paddock system. Build them strong.
Simple gate design: Two stout posts set close together (gate width: 10-12 feet for cattle, 4-6 feet for sheep). Hang a wooden gate frame from one post using leather hinges or wooden pivot pins. A drop bar or rope loop secures the gate closed.
Movement tips:
- Always move animals in the same direction through your rotation — they learn the pattern and eventually walk to the next paddock willingly
- Move animals in the morning when they are hungry — they walk toward fresh grass eagerly
- One person can move a trained herd of 30+ cattle by simply opening the next gate
Temporary Subdivision
Sometimes you need to split a paddock temporarily — during a drought to limit grazing, or to strip-graze a stockpiled paddock in winter.
Quick methods:
- Thorn brush line — drag dead thorny branches into a line across the paddock
- Hurdle panels — pre-built wattle panels you can set up and move (store them stacked when not in use)
- Rope and flag line — trained cattle will respect a rope strung between temporary posts, especially with cloth flags that move in the wind (this takes training but uses minimal materials)
Key Takeaways
- Every paddock must have water access — design your layout around water first, everything else second
- A central lane system is the most practical layout for most properties, allowing easy animal movement without crossing other paddocks
- More paddocks means longer rest periods — aim for at least 8 paddocks to achieve meaningful pasture recovery
- Size paddocks by carrying capacity, not by area — lush ground can be smaller than poor ground
- Wattle fences and thorn barriers are effective low-technology options for internal divisions
- Build perimeter fences strong, interior fences can be lighter — perimeter keeps animals on your property, interior just directs movement
- Train animals to respect fences early — a few days of consistent containment builds lasting habits
