Technical Abstract: Data on the off-site movement and fate of veterinary pharmaceuticals is needed in order to better manage these products. The benefits of these chemicals are well established; however, little information exists on their potential for environmental harm. An essential initial step to understanding this problem is to determine their potential for release and exposure. Three compounds (monensin, lasalocid and doramectin) were specifically studied in this report. These compounds were known to be administered to calves managed in a calving enclosure located on the Western Kentucky Agricultural Research and Education Complex. Their distribution was monitored in soil samples collected across the surface of the enclosure. Initial data show that the majority of the compounds remained in the upper open barn area, while varying amounts of each migrated downslope to a retention basin at the bottom of the facility. Data will also be presented for bacterial density and other compounds.
