ABSTRACT
The sustainability of all productive activities, including livestock farming, becomes a fundamental challenge in the current scenario. Livestock production faces both old and new challenges related to climate change, food safety, and feed-food competition. The latter aspect has recently become a hot topic, and many researchers are turning their attention to this issue. According to circular economy principles, former foodstuffs have characteristics that make them a promising source of raw material for animal feed. The main objective of the present review is to provide a brief overview of the most recent studies (published between 2016 and 2022) addressing the dietary inclusion of former foodstuffs for livestock. The articles analyzed cover key findings from both in vitro and in vivo studies of former foodstuffs included in the diets for pigs, cows, and broilers, and assess the associated safety aspects. The articles provide information on livestock performances and product quality, as well as feed digestibility, fecal microbiota, and blood analysis. Although the evidence supports the inclusion of former foodstuffs in livestock diets as a safe, effective, and sustainable ingredient, this analysis of the most recent literature also highlights gaps in our knowledge that need to be filled. The present overview will help researchers plan future research and standardize and promote the inclusion of former food products in livestock diets.
