Abstract: Antibiotics are used as the main feed additives in livestock and poultry. However, their extensive applications over the past decades have resulted in a series of problems which are needed urgently to be solved. For example, antimicrobial resistance of pathogenic bacteria has been enhanced, animal immunity and animal vaccine titer have been reduced, and human health has been affected through food chain. China′ s Ministry of Agriculture and Rural Affairs had issued a notice that the use of antibiotics additives should be banned in China′ s feed industry since the year of 2020, and the feed industry has officially entered an antibiotic-free era. For a long time, researchers have been actively seeking to develop various antibiotics substitutes as well as green and harmless feed additives to eliminate or mitigate the influences brought by prohibition of using antibiotics. In this paper, the antibacterial characteristics and mechanisms of the main antibiotics substitutes are reviewed, in hoping to provide references for the application of antibacterial additives in feed after the ban of antibiotics.

Key words: antibiotics substitutes, feed additives, action mechanism
