Potato protein concentrate: a possible alternative to the use of antibiotics in diets for weaned piglets. Review. Rev. mex. de cienc. pecuarias [online]. 2022, vol.13, n.2, pp.510-524.  Epub 20-Jun-2022. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v13i2.5980.

The weaning period is critical in the life of piglets and can cause gastrointestinal disorders and low growth, which are lessened with the use of antibiotics in starter feeds. However, due to the need to eliminate antibiotics from animal nutrition, some possible alternatives to their use are mentioned. In this literature review, antimicrobial peptides and plant-derived protease inhibitor compounds are described, especially those from potatoes, which have traditionally been recognized for their potential biomedical application and activity against pathogenic bacteria and fungi. The characteristics and applications of potato protein concentrate (PPC) from the starch industry, which is distinguished by its amino acid profile and high digestibility, were reviewed. Molecules that are present in the protein fraction and that can contribute to the intestinal health of piglets stand out in PPC, so it is emerging as an ingredient with potential to be used in antibiotic-free diets. However, it is necessary to have more bibliographic information on PPC to verify whether the health response is consistent or not, and to recommend its inclusion in starter diets for newly weaned piglets as an alternative to antibiotics.
