Net returns to feeding were calculated for preconditioning. The added value to cattle feeders, without accounting for death loss, from purchasing preconiditioned calves over calves of unknown origin is $46.83/head and $49.54/head for the CPH and GT calves, respectively. As a result, a feedlot operator could pay $8.50/cwt and $9.00/cwt more per 550 pound CPH and GT feeder calves, respectively, and still maintain the same level of profit.
