Feedlot

A feedlot or feedyard is a type of concentrated animal feeding operation (CAFO) (also known as "factory farming") which is used for finishing livestock, notably beef cattle, prior to slaughter. They may contain thousands of animals in an array of pens. Most feedlots require some type of governmental permit and must have plans in place to deal with the large amount of waste that is generated. Long-running feedlots are often exempt due to various "grandfather clauses", which allow feedlots to wait until a change of ownership before obtaining permits and designing formal waste management plans.

A confined area for the controlled feeding of animals. Tends to concentrate large amounts of animal waste that cannot be absorbed by the soil and, hence, may be carried to nearby streams or lakes by rainfall runoff.

Confined outdoor or indoor space used to raise hundreds to thousands of domesticated livestock. See rangeland.

A confined cattle feeding facility where feeder cattle (usually less than a year old) are put on higher protein rations to prepare them for slaughter as fed cattle at "good" or better grades. Commercial feedlots of 1,000 head or more are considered by the Environmental Protection Agency to be concentrated animal feeding operation (CAFO) and therefore subject to rules requiring permits setting effluent standards.
