Peptides,consisting of 2～20 amino acids,are small-chain proteins that serve crucial biological functions in organisms.These functions include the regulation of growth and development,immune responses,metabolic control,and antimicrobial activity.Producing bioactive and functional peptide feed from various sources such as plants,animals,and by-products of food processing is an effective method for addressing the protein scarcity issue.This review aimed to introduce the production methods and functional classification of peptides,and provide a summary of their mechanisms of action in growth,immunity,antioxidant capacity,and the intestinal digestion system.This would contribute to understanding the mechanisms of peptides in feed,improving peptide performance and utilization,and developing more environmentally friendly,healthy,and efficient peptide-based bioproducts.These studies were significant for enhancing animal production efficiency,protecting the environment,and promoting sustainable development in animal husbandry.
