are popular with horses for
chewing, cribbing, wind sucking, and other
vices. If a rail comes loose, a nail may stick out
and cut the horse. If a rail breaks, it can be lethal
to horses. Some have been killed by spearing
themselves through their chests with a piece of
wood rail. It's possible to protect such fences by
running a strand of tape along the top rail.
Electric string offers limited physical
protection as it is easily breakable, limiting its effectiveness.
Electric string can easily short-circuit, because
with only three threads of wires the charge is distributed unevenly over its length.
The string is too small for a horse to see. The string does not give a sufficient shock
to warn the horse.
: Electric cord is significantly stronger
than electric string (resistant to two tons of
pressure). However, frightened animals pushing against it can damage themselves
(particularly where visibility remains an issue).
In Sweden we know of more than six cases where horses have been permanently injured.
The Dutch National Stud Farm installed it to enclose her stallions.
The result is in the picture.
Pig Netting or Electric Netting
: This form
of mesh is commonly used with smaller
animals. However, there is a strong risk
that horses will get a limb tangled in the
mesh, and be unable to withdraw it while
in a frightened state.
nice when new and are safe. However, horses do use it to rub against them.
An adult horse can exert about 500 pounds of lateral pressure and
this quickly plays havoc with plastic fencing. Ideally vinyl should
be protected with one or two strands of electric tape.
