While it is not true that a goat-proof fence must also be airtight, to frustrated goat farmers, it is sometimes difficult to distinguish the difference. This is mainly because they started with something less than adequate and were forced into a "patch" job. With such a beginning, one is soon patching one's patches. Effective goat fencing of the conventional (non-electrical) type is approached in one of two ways. This may be of woven wire, or alternatively, closely-spaced barbed wire.
Fencing is a most critical factor in raising goats on pasture. There is nothing more frustrating than having to constantly chase goats back into the pasture. Fencing needs to not only keep the goat in the lot but also should be designed to keep the predators away from the goats.
Fencing will also be the greatest expense, other than the initial cost of the animals. One good permanent fencing is 4-foot woven wire with barbed wire along the top. Some grazers are also successfully using four or five strands of high-tensile electric wire which is less expensive than woven wire. Please see Goat Pastures Fences for additional information.
