A goat uses vision to recognise a traditional electric fence. A goat that has never been in contact with a traditional electric fence doesn’t know that it causes discomfort. It is widely known that the animals quickly learn to stay away from the fence and that they use their sense of sight to recognise the fence, thus avoiding unpleasant electric shocks. In comparison, the animal will use its well-developed sense of hearing and will also notice the vibrations in the collar to recognise the Nofence boundaries. There is documented evidence that it takes goats a short period of time to learn this warning. They then use their sense of hearing to recognise when they need to turn around to avoid the discomfort associated with the electric shock.
A traditional fence has an absolute boundary. The warning field for Nofence has a certain scope in terms of both time and distance so the animal will have enough time to understand the fencing function, turn around, and go back. The Nofence boundary should therefore be considered a zone instead of a hard boundary.
Another significant difference between a traditional fence and Nofence concerns escape. It is difficult for a goat to escape from a traditional electric fence. Therefore, it can lead to risk of getting caught in the fence and receiving a continuous shock. Nofence gives the goat the possibility to weigh the short-term discomfort of escaping against the reason it wants to escape. Nofence expects hunger, thirst, herding instinct, and predator attacks to be situations that may cause a goat to choose to escape. In such situations, Nofence believes it is good animal welfare to give the goats this possibility.
