抗菌肽在生猪养殖中的应用

Application of Antibacterial Peptides in Pig farming

抗菌肽(antibacterial peptides,ABP)是具有抗菌活性短肽的总称,是机体先天性免疫系统的重要组成部分。目前已从动物、植物、昆虫和细菌中发现抗菌肽6000多种,部分抗菌肽已应用于医药、食品和农业等行业。随着抗生素耐药性的出现,抗菌肽越来越受到重视。与抗生素相比,抗菌肽具有广谱抗菌、抗病毒、杀死癌细胞、提高机体免疫力、抗菌机理独特以及无残留等优点,在畜牧领域具有良好的应用前景。本文简要介绍了抗菌肽的分类、主要功能以及在生猪上的应用,提出了抗菌肽的问题和展望,有利于促进抗菌肽的进一步研发和应用。

Antibacterial peptides （ABP） are the general name of antibacterial active peptides, which are important parts of the innate immune system of living organisms. More than 6000 antimicrobial peptides have been found in animals, plants, insects and bacteria, and some of them have been used in medical, foodand agriculturalfield. With the emergence of antibiotic resistance, antimicrobial peptides are more and more concerned. Compared with antibiotics, antibacterial peptides have the advantages of broad antibacterial spectrum, antiviral and killing cancer cells, enhancing immunity, and unique antibacterial mechanism, and no residue. Overall, antimicrobial peptides have a good application prospect in the field of animal husbandry. This paper briefly introduces the classification, main functions of antimicrobial peptides and their application in pigs, also raises the questions and prospect of antimicrobial peptides, and the authors hope promotes the development and application of antimicrobial peptides further.
