Allium fistulosum L., commonly called spring onion, welsh onion, or Japanese bunch onion, is a clumping, slowly spreading, evergreen perennial type that is mainly grown as a vegetable because of its onion-scented leaves. This species is very similar in taste and smell to the related common onion, Allium cepa, but does not develop bulbs. Welsh onion were detected to contain volatile compounds containing sulphur and polyphenolic compounds which exhibit various biological activities, and which have anti-fungal, anti-oxidative, anti-hypertensive, anti-platelet, regulation of immune function and anti-obesity effects. This plant is much less known in the world than the traditional onion, A. cepa. This review intends to describe and summarize recent advances the nutrients and phytochemicals of welsh onions for using as a poultry alternative feed additive, their beneficial effects, and the mechanisms underlying their involvement for future in poultry nutrition.
