Abstract
Plant essential oils,as natural bioactive substances,commonly contain active ingredients which have multiple functions including antibacterial,anti-inflammatory,and antioxidant properties.They play an im-portant role in improving the average daily gain of weight in weaned piglets and fattening pigs,and reducing the feed-to-weight ratio.This article reviewed the main active ingredients of plant essential oils in common and explained their mechanisms of exerting antibacterial,anti-inflammatory,and antioxidant effects by disrupting cell membranes in bacteria,regulating the NF-κB signaling pathway,and quenching free radicals to clarify the effects of application and the mechanism of plant essential oils as green additives for feed in pig farming.The positive effects of adding plant essential oils to the diet on the growth performance,immunity,and gut health of pigs were elaborated in details.It was proposed that the combination of essential oils and microcapsule coating technology has a synergistic effect.It will provide a theoretical basis for the scientific application of plant essen-tial oils in pig farming and the development of antibiotic-free formulas of feed.关键词
