This project will realize invisible fencing of grazing animals.

pastures in Norway is exposed to strong increase of scrub. The only way to overcome this problem is to use grazing animals in landscape care. As it looks, there are fewer and fewer animals in the outfield. This is a development which, together with environmental effects, is accelerating this problem. Grazing animals has to be used to overcome this problem. To achieve this, the fence issue is to be resolved. Fences are the main reason why farmers are reluctant to use grazing animals.

It is planned that a product will be on sale in 2012.

 

We regret to announce that this English version will not be updated as frequently as the Norwegian version.

Preliminary test results from a goat herd

Testing on goats, done by Bioforsk Organic, is now completed. The results will officially be released during October/November. But so far our experiences shows that goats can learn the system, after having tried the limits sometimes. To determine the animals' welfare by the use of NoFence, we have to wait for the official report. Read more.

Video presentation of the NoFence technology is posted

Here is a presentation if the NoFence technology. (in norwegian).

Oscar Hovde Berntsen, 29. january 2010.

Testing will be done in cooperation with Bioforsk Økologisk.

In late 2009, it was defined by a working group that would work with the continuation of the project. This group consists of:

The work group has focused on the financing of further development and testing.

The project has been divided into two subprojects:

  • Further development of the technique. (Oscar H. Berntsen)

  • Testing on animals. (Britt I. F. Henriksen, Senior Researcher at Bioforsk Økologisk)

The work is now focusing on preparation for experiments with animals. The goal is to get permission to experiment, so that testing on sheep and goat can begin. The tests will provide answers, and tell if NoFence can be recommended regarding to animal welfare. There is a strong desire that NoFence improves animal welfare in that it is easier to have animals on pasture without increased animal stress.

Name change

A decition to change the name form nOFence to NoFence has been made. This is to avoid the two words.

Simple presentation

This is a powerpoint format, it actually requires some verbal explanation. But some of you might find it interresting anyway.

Patent pending.

Eventually the patent is sent. Writing has been time demanding, but it is finally completed. It will now be somewhere between 6 and 7 months before the first statement from the Patent Office.

Read the patent summary here.

First test of nO Fence-Proto v0.1 is done. Read as .pdf (norwegian)

The testing was done on 03.10.2009.


The goats were fenced using conventional electrical fence. The area in nO Fence was set so that one invisible fence line divided the area in 2 That is, the goat that was equipped with nO Fence should not be able to go into the northern part of the corral. This goat was the boss of the herd. The group consisted of 10 goats.


When the collar was placed on the goat, it was lid through the invisible fence line by using bread. This goat was the first, the rest of the herd followed. When the goat crossed the invisible line, it became aware of the first warning, and was somewhat skeptical, but continued on, slowly. When continuous alert began, the goat was so skeptical that it turned, and walked back to where it came from. It was however worried when it detected all the others went to the bread. It went out of the area again, with the same approach. This happened 2 times. Not before the third attempt it went so far that it experienced the electrical shock. The reaction was "absolutely correct" it was quick to get back to where it came from.

The electrial shock was so weak that it did not hurt. The undersigned have tried it several times. It's just uncomfortable.

The result after this first test must be said to be far above every expectation. Remember, this is only one goat. In order to have good test results to refer to it needs, of course, more testing. On several goats over longer timespan.
