“…The objective of the present review was to provide a concise overview of the most recent studies on FFs inclusion in livestock feed, including studies addressing the effects on growth performances, nutrient digestibility, gut microbiota, hematological parameters, product quality focusing on both monogastrics and ruminants, particularly in poultry, and animal-derived food quality (Afzalzadeh et al 2007 ; Almeida et al 2011 ; França et al 2012 ). Although few articles have covered this topic before, the existing literature lacks sufficient focus on poultry nutrition (Pinotti et al 2021 , 2023 ). This analysis also revealed the gaps in our knowledge which need to be filled for the feed industry to evolve and promote the use of FFs in animal nutrition.…”

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.
