Electronic (Fenceless) Control of Livestock

摘要

During June and August 1992, we tested a new technology designed to exclude211u001ecattle from specific areas such as riparian zones. Technology consisted on an 211u001eeartag worn by the animal that provides an audio warning and electrical stimulus 211u001eto the ear as the animal approaches the zone of influence of a transmitter. The 211u001etransmitter emits a signal that narrowly defines the desired area of exclusion. 211u001eTests on cattle indicated that the technology is about 90 percent effective at 211u001eexcluding animals. This technology has been patented, and the Forst Service is 211u001epursuing ways to develop the product for marketability.
