ヤギ用フェンス計算ツール

A goat fence calculator has to account for an animal that treats most standard field fencing as a climbing frame rather than a boundary. Goats lean on fences to test them, climb when there is anything to get a hoof on, and jump heights that would contain cattle or sheep without hesitation, and horned breeds face an added risk of getting their heads and horns trapped in wide-mesh field fence. The fix is a woven wire mesh with tight, consistent 4x4-inch anti-climb openings rather than the larger 6x6-inch spacing used for cattle, and this calculator sizes that specific material: 330-foot woven wire rolls, steel line T-posts, corner anchor assemblies, and the wire clips that fasten mesh to post at the spacing the fence actually needs.

Height is the first decision and it depends on the breed as much as the dog fence calculator's height depends on the specific dog. A 48-inch fence is the standard minimum for ordinary meat and dairy goats, but athletic or Boer-type breeds that are confirmed jumpers push the design to 60 inches, and there is no reliable shortcut around testing the actual animals rather than assuming a breed average holds. Barbed wire alone does not work for goats the way it works for cattle, since goats crawl underneath a widely spaced strand or squeeze between barbed lines rather than respecting the barrier the way cattle generally do; woven mesh with an optional electrified top wire is the combination that actually holds, with the electric line discouraging the climbing and rubbing that wire mesh alone cannot fully stop.

Line post spacing runs tighter on a goat fence than on most livestock fencing, commonly around 10 feet rather than the wider 12 to 16 foot spacing cattle fencing tolerates, because goats lean on wire hard enough to crush it down over a longer unsupported span. Corner and end assemblies still use the same heavy treated wood H-brace construction that carries tension on any wire fence, since the loads at a corner do not change just because the animal is smaller. The bottom wire deserves particular attention: keep it within an inch or two of the ground so kids and small-statured adult goats cannot crawl under a gap that would never contain a larger animal. Tensioning the mesh correctly, until the horizontal crimps in the woven wire flatten by roughly half their depth, keeps the fence from sagging into a climbable, ramp-like angle within the first season.

Goat fencing shares equipment and technique with the rest of the livestock calculators on this site more than it differs from them. The cattle fence calculator uses the same corner-brace logic with barbed wire strands instead of woven mesh, and the horse fence calculator swaps in smooth rail because horses cannot tolerate barbs the way cattle can. If the same enclosure also needs to keep a family dog contained, the dog fence calculator handles that separately, and where goats share ground with vegetable beds the garden fence calculator adds the underground apron that wire mesh alone does not provide. The guide on horse and livestock fencing basics covers bracing and tensioning that applies across species, and the piece on the best fence for a dog is useful if goats and dogs are sharing the same pasture line.

Once the mesh height and post spacing are chosen, run the perimeter through the fence perimeter calculator if the paddock is not a simple rectangle, and check post depth against the fence post calculator for your local frost line. The fence materials guide compares woven wire against the other mesh and panel options on this site, and the fence cost guide covers how to turn a wire and post count into a realistic budget before ordering rolls. The complete set of livestock and animal fencing calculators, cattle, horse, dog and garden included, is grouped under the animals category page.

It is worth sizing the fence for the most capable goat in the herd rather than the average, since a single determined climber or jumper will find the one weak section of an otherwise adequate enclosure and the rest of the herd tends to follow once a breach is found. Horned and polled goats also behave differently around fencing: horned animals are the ones most likely to get a head caught in oversized mesh, so a mixed herd of horned and polled goats should be fenced to the horned animals' requirements rather than assuming the polled goats set the standard. Routine checks matter as much as the initial build. Mesh that was tensioned correctly at installation can sag after a season of leaning and weather, so walking the fence line periodically and re-tensioning sagging sections before a goat discovers the gap keeps a well-built enclosure from slowly becoming a climbable ramp. Clip count matters too: a post with only one or two clips holding the mesh gives a leaning goat more leverage to peel the wire away from the post than a post with a full set of clips spread top to bottom, so it is worth checking clip counts on an older fence line before assuming the mesh itself has failed.
