Common names 

Potato pulp, potato peels

Description 

Potato by-products are numerous and very variable depending on the processing method that yielded them.

Most current potato byproducts are : potato meal, potato flakes, potato slices and potato pulp.

This is particularly true of potato pulp, whose protein and fibre content depends on the proportion of potato solubles added back into the material. Therefore, it is necessary to have such materials analysed chemically before  feeding livestock or to purchase them on the basis of a guaranteed analysis (Blair, 2008).
