Powerfields USA-made electric netting is an electrifiable, already-assembled, portable fence. It is purchased in a roll complete with built-in line posts. Fence construction can be complete in 10 minutes and is as simple as unrolling, stepping in the posts, and attaching a fence energizer. Portable electric net fences make rotational grazing, handling small-scale herds, and backyard poultry simpler.  Advantages of rotational herd or flock movement are breaking parasite cycles, providing fresher forage, and allowing time for the replenishment of pastures.
