614628 Disclosed is a fence line (1) having a series of electrified wands (4). When animals repeatedly contact the fence line (1), the fence line (1) is weakened by the contact. Delivering electric shocks to the animals deters the animals from contacting the fence line (1). The fence line (1) has a series of electrified wands (4) which extend outwards from the fence line (1) at intervals. Each wand (4) is arranged such that in the event of livestock animals walking along the fence line (1), a livestock animal will contact an electrified wand (4). The electrified wand (4) will move in the direction in which the animal moves. The electrified wand delivers an electric shock to the animal in order to deter the animal from walking along the fence. After the shock has been delivered, the wand (4) moves back into its initial position prior to being contacted by the animal. Each wand (4) comprises an electrical insulator sleeve (14) and a metallic arm (5).
