Potatoes are an important human food and many potatoes are processed before marketing. It is estimated that 33 kg of waste is produced for each 100 kg of potatoes processed. Considerable processing occurs in the northwest United States, and much of the waste (byproduct) is fed wet to beef cattle in feedlots. Because of the high starch content, potato waste has high feed value similar in energy to corn or barley. The practical limit of its use in cattle diets is 30 40% of the dry matter. This is a high-value by-product and is essentially the basis for the cattle-feeding industry in Idaho and Washington.
