What fencing options work best for livestock security?

High-Tensile Wire Fencing

High-tensile wire fencing is an effective option for securing livestock. It consists of a strong, thin wire (typically 12.5 gauge or smaller) stretched tightly between posts. For a 3-strand fence, use 12.5-gauge wire for the top and bottom strands, and 14.5-gauge wire for the middle strand. Space posts 12-15 feet apart, and tension the wire to 900-1,000 pounds per inch. This type of fencing is particularly effective against large predators like coyotes and mountain lions.

Electric Netting

Electric netting is another excellent option for securing small to medium-sized livestock. It consists of a lightweight, electrically charged net that can be easily moved or repositioned. For large animals like cattle, use a 42-inch tall net with 4-inch mesh size and 6,000-7,000 volts. For smaller animals like sheep and goats, use a 30-inch tall net with 2-inch mesh size and 3,000-4,000 volts. Install netting around the perimeter of the enclosure, and ensure it is at least 12 inches off the ground to prevent animals from contacting the wire.

Woven Wire with Barbed Wire

Woven wire fencing with barbed wire is a tried-and-true method for securing large predators. Use a 3-strand woven wire fence with 2x4 inch openings, spaced 12-15 feet apart. Add barbed wire to the top strand, with the barbs facing outward to deter climbing. For added security, use a 12-inch wide strip of barbed wire along the bottom of the fence. This type of fencing is particularly effective against large predators like wolves and bears.
