Horse Care - Pasture/Turnout/Fencing

Fences and Pens Horses evolved to live on prairie grasslands and to cover long distances unfettered by artificial barriers. Therefore, when fenced in, accident potential must be considered. Horses will put their heads and legs through fences in an attempt to reach forage on the other side. They may run into fences if chased by another animal, or even when running at play if the fence (such as a wire fence) is not particularly visible. The smaller the area, the more visible and substantial a fence needs to be. For exercise alone, a pen, run, corral or "dry lot" without forage can be much smaller than a pasture, and this is a common way that many horses are managed; kept in a barn with a turnout run, or in a dry lot with a shelter, feeding hay, allowing either no pasture access, or grazing for only a few hours per day. Outdoor turnout pens range greatly in size, but 12 feet (4 m) by 20 to 30 feet (9 m) is a bare minimum for a horse that does not get ridden daily. To gallop for short stretches, a horse needs a "run" of at least 50 to 100 feet (30 m). When kept in a dry lot, a barn or shelter is a must. If kept in a small pen, a horse needs to be worked regularly or turned out in a larger area for free exercise. A sturdy and well-made wooden post and rail fence that is suitable for horses Fences in pens must be sturdy. In close quarters, a horse may contact the fence frequently. Wire is very dangerous in any small pen. Pens are often made of metal pipe, or wood. Larger pens are sometimes enclosed in closely woven mesh, sometimes called "no climb" fencing. However, if a wire mesh is used in a small pen, the openings must be too small for a horse hoof to pass through. Types of fencing Over vast areas, barbed wire is often seen in some parts of the world, but it is the most dangerous fencing material that can be used around horses, even in a large pasture. If a horse is caught in barbed wire, it can quickly become severely hurt, often leaving lasting scars or even permanent injuries. Horse management books and periodicals are nearly universal in stating that barbed wire should never be used to contain horses. However, this advice is widely ignored, particularly in the western United States. Various types of smooth wire fencing, particularly when supported by a strand of electric fence, can be used to enclose a large pasture of several acres, and is one of the least expensive fencing options. A wire fence should have at least four, preferably five strands to provide adequate security. However, even without sharp barbs, wire has the highest potential for horses to become tangled in the fence and injured. If used, it must be properly installed and kept tight through regular maintenance. Visibility is also an issue; a horse galloping in an unfamiliar pasture may not see a wire fence until it is too late to stop. A heavy woven mesh with closely spaced strands is relatively safe for horses, as they cannot easily break the fence nor put a foot through it Woven mesh wire is safer but more expensive than strands of smooth wire. It is more difficult to install, and has some visibility issues, but horses are less likely to become tangled in it or be injured if they run into it. Adding a top rail of wood or synthetic material increases visibility of the fence and prevents it from being bent by horses reaching over it. A strand of electric fence may also keep horses from pushing on a mesh fence. Mesh fencing needs to be heavy-gauge wire, woven, not welded, and the squares of the mesh should be too small for a horse to put a foot through. "Field fence" or "no-climb" fence are safer designs than more widely woven "sheep fence." Chain link fence is occasionally seen, but horses can bend chain link almost as easily as a thinner-gauge wire, so the additional expense is often not justified by any gain over good-quality woven wire.
