Common names 

Potato protein concentrate [English]; concentré protéique de pomme de terre [French]

Description 

Potato protein concentrate is a byproduct of potato starch production. Consisting in almost pure protein, it is of outstanding nutritive value for all classes of livestock.

Potato protein concentrates

Potato protein concentrates originating from starch industry have been tested in broilers. Levels of incorporation below 5 to 10% did not affect growth significantly, while higher levels depressed feed intake and growth performance (Tusnio et al., 2013); Gerry, 1977). Highest potato protein concentrate levels led to sticky feeds and litter problems (Gerry, 1977). Comparison of batches differing in antinutritional factors (trypsin inhibitors and solanidine glycoalkaloids) failed to show a relationship between antinutritional factors and growth performance (Tusnio et al., 2013). An inclusion level of 5% can be recommended as safe in broiler diets.

Low levels of potato protein were tested as alternative to antibiotics due to their antimicrobial effects (Ohh et al., 2009). However the effect on growth performance, digestibility, and microbial populations was low, and in any case below this of antibiotics (Ohh et al., 2010).
