abstract

Abstract Not Available – First paragraph follows:

Depending on the particular shipment, 25 to 90 percent of the feeder and stocker cattle coming into southern California desert feedlots get sick. Death losses and culling rates range from 6 to 8 percent among the lighter calves (250 to 400 pounds) and from ½ to 2½ percent for larger animals.
