Última FEEDLOT '99, PART I: BASELINE REFERENCE OF FEEDLOT MANAGEMENT PRACTICES, 1999 AgEcon The National Animal Health Monitoring System (NAHMS) is sponsored by the USDA:APHIS: Veterinary Services (VS). The NAHMS Feedlot '99 Study included feedlots of 1000-head or greater capacity from the 12 leading cattle feeding states. Feedlots included in the study represented 84.9 percent of U.S. feedlots of this size and contained 96.1 percent of the U.S. feedlot cattle inventory on feedlots with 1000-head or greater capacity as of January 1, 2000. For the purposes of the study, operations were grouped into two size categories: those with capacities of between 1000 and 7999 head, and those with capacities of 8000 head or more. Beef animals were the main type of cattle placed in feedlots regardless of operation size. Approximately one-half of the placements...

Dissolved and particulate Hg fluxes in the Lot-Garonne-Gironde fluvial-estuarine system were obtained from observation of daily discharge and suspended particulate matter (SPM) concentrations. In addition to the measurements of the total dissolved (< 0.45 gm) and particulate Hg (> 0.45 gm), called HgTD and HgTp respectively, the dissolved inorganic Hg species (HgRD) were determined monthly. Geochemical background values for HgTp in sediments and SPM were similar to crustal values and to typical concentrations in SPM of non-contaminated river systems, respectively. The Riou Mort watershed already known as the origin of important historical polymetallic (e.g., Cd, Zn) pollution was identified as an important Hg point source. In the downstream Lot...
