Potato processing and consumption have slowed due to the popularity of low-carbohydrate diets, meaning some potatoes may be going to waste, says Greg Lardy, an extension specialist with North Dakota State University.
Lardy encouraged cattle producers to consider using excess spuds to feed cattle.
“Potatoes have a feeding value equal to barley on a dry matter basis,” Lardy said. “They are high in energy, but low in protein and vitamin A.”
In finishing rations, satisfactory results can be obtained by feeding potatoes as a portion of the ration, along with cereal grains such as barley or corn, a protein supplement and roughage, he said.

It’s important for agricultural producers to be at the table when policy is decided, not only nationally but also internationally.
Potatoes can make up a maximum of 50 percent of the ration on an as fed basis for finishing cattle.
“Potatoes should be worked into cattle diets gradually to prevent digestive disturbances and should not be removed after cattle have adapted.”
Potatoes can be fed whole, but chopping them prevents cattle from choking. The risk can also be minimized by feeding out of low feed bunks or on the ground. Frozen potatoes should not be fed, because choking is more likely.
Producers should also be cautious of sprouted potatoes, which contain toxic alkaloids.
Potatoes can also be spread on pastures or fields and freeze-dried over the winter. Cattle then consume them in the spring.
