Abstract: The raw material sources, active ingredients and extraction process of botanical extract and its functional and safety evaluation as feed additive are summarized. The active ingredients of plant extracts mainly include plant polyphenols, alkaloids, volatile oils, organic acids, polysaccharides and plant pigments. The extraction processes include supercritical fluid extraction, subcritical fluid extraction, enzymatic extraction and semi-bionic extraction, etc. Botanical extract with antioxidant and antibacterial properties can improve the poultry gastrointestinal functions and production performances.

Key words: botanical extract, active ingredient, feed additive, extraction process, gastrointestinal protection, safety assessment
