抗菌肽在饲料中应用的优势

The Advantage of Application of Antimicrobial Peptides(AMPs) in Feed

食品安全与耐药性是近年来多方关注的热门议题,为了防止畜禽养殖过程中滥用抗生素导致的耐药性问题扩散到人类身上,越来越多的抗生素被禁止在动物养殖中使用。预计未来几年还会有更多的抗生素被禁用,多种抗生素替代产品也次第出现,而抗菌肽是其中具有极大潜力的替代物之一。本文将对抗菌肽在饲料中应用的优势加以探讨。

The increasing problem of multiple drug resistance bacteria and the concern of health risk from chemical food safety have lead to a request of new antimicrobial strategies. In addition, the extreme and uncontrolled use of antibiotics in livestock and poultry caused antibiotic residues in meat that can pose certain hazards to human health. Several kinds of antibiotics are banned as feed additive and they will be prohibited to use as growth promoters in the next few years. Antimicrobial Peptides are positively charged and large proportion （generally 〉 50%）of hydrophobic residues. The ability to associate with microbial membrane is a characteristic of AMPs. AMPS are one of the great choice for control microbial and stimulate livestock immune. This article will discuss the advantage of the use of AMPS in livestock feed.
