Producers should collect and store runoff from holding pens for later land application. Runoff control systems collect feedlot runoff, settle out manure solids, and direct the remaining runoff water to detention ponds. Figure 1 shows a livestock feedlot runoff control system for an open lot surface. Feedlot Cleaning Livestock feedlot surfaces should be cleaned regularly. Cleaning and scraping once per week is preferable for dairy cattle, or once every month or two for beef cattle.
Concrete surfaces are easier to clean than earthen lots.
Earthen yards are usually cleaned when dry, so solids may be removed less frequently. Earthen yards can be cleaned only once or twice per year. The area needed per animal to minimize the risk of ground water contamination depends on the type of lot surface. The area needed for a concrete surface is much less than that required for an earthen lot. The concrete area needed is a balance between traffic on the lot and the resting area provided for animals.
