ABSTRACT Food leftovers can be used as alternative feed ingredients for monogastric to replace human‐competing feedstuffs, such cereals, recycle a waste product, reduce the feed‐food competition and keep nutrients energy in chain. Among food leftovers, former products (FFPs) are no more intended human but still suitable animal consumption. However, metabolic impact of FFP has never been investigated. In this study, we evaluated replacing 30% conventional cereals with on abdominal fat quality plasma metabolome modulation postweaning piglets. Thirty‐six Large White × Landrace piglets (28 days old) were randomly assigned three dietary groups 42 days: control (CTR), replacement CTR salty (SA), sugary (SU). Body weight intake measured calculate average daily gain, conversion ratio. The fatty acid profile diets adipose tissue was determined mass spectrometry‐based untargeted metabolomics investigation performed samples. growth performance not significantly affected by SA SU diets. Despite different diets, rebalanced time factor rather than treatment factor. Six metabolites altered compared CTR: caffeine, theobromine, proline‐betaine, dipalmitoyl‐phosphatidylcholine (PC 32:0), spermidine l ‐tryptophan. Caffeine glycerophospholipid pathways between groups, although other observed. Overall, limited fat, related demonstrated value innovative sustainable feedstuffs.
