Interestingly, they did not put the collar on every goat. Just putting the collars on a few goats, kept all the goats contained as the un-collared goats did not want to stray too far from the herd being pack animals. We have noticed a similar phenomenon with dogs. When you put the collar on the lead dogs in he pack, the other dogs tend to stay close by. Young dogs may still wander, particularly young male dogs! But, generally everyone else stays close to the pack leader.
Goats (Capra hircus ) are useful for brush and weed control. Their usefulness would be enhanced if their distribution on grazing land could be controlled without herders or permanent fencing. The feasibility of using electric shock collar to restrict the range of grazing goals was evaluated. Electric shock collars developed for canine control were tested as an alternative method for unattended containment. Shock collars effectively contained goats within the designated test area. Goals not wearing the shock collars remained close to the collared goats due to herd instinct and thus also remained with in the test area. Preliminary results indicate that the non-visual fence may make it feasible to develop commercial weed-grazing goat herds restricted to weed infestations by electric collars.See the full article here. * Invisible Fence is a registered trademark of the Radio Fence Company.
