"  GPS AND LAPTOP A GPS unit feeds into Cox&amp;#039;s laptop, which uses GIS software to map the ranch&amp;#039;s 27,000 semi-arid acres and pinpoint the more than 100 pasture areas and water sources. LIVESTOCK TAGS AND COLLARS Demonstrating what&amp;#039;s in store for all U.S. livestock, Cox&amp;#039;s 300 head of cattle and 190 sheep are fitted with RFID ear tags for tracking. Select cows sport pricier GPS collars. BOOTS AND HAT Ostrich-leather Lucchese riding boots can last Cox a decade, while he wears out his everyday work boots in about nine months. A 10x Stetson hat helps keep the sun at bay. HIGH-TECH FARMHANDS Digital hubs (not shown) update Cox on weather and soil conditions. In development: a telemetry device to detect every bite taken by a cow as well as the type of plant being devoured. &amp;quot;In a day, I could be tracking down antelope by helicopter, analyzing forage availability or doing an ultrasound on a sheep.&amp;quot; "^^<http://www.w3.org/2001/XMLSchema#string>
