Nanoparticles have been used as diagnostic and therapeutic agents in the human medical field for quite some time, though their application in veterinary medicine and animal production is still relatively new. Recently, production demands on the livestock industry have been centered around the use of antibiotics as growth promoters due to growing concern over microbial antibiotic resistance. With many countries reporting increased incidences of antibiotic-resistant bacteria, laws and regulations are being updated to end in-feed antibiotic use in the animal production industry. This sets the need for suitable alternatives to be established for inclusion in feed. Many reports have shown evidence that nanoparticles may be good candidates for animal growth promotion and antimicrobials. The current status and advancements of nanotechnological applications in animal production will be the focus of this review and the emerging roles of nanoparticles for nutrient delivery, biocidal agents, and tools in veterinary medicine and reproduction will be discussed. Additionally, influences on meat, egg, and milk quality will be reviewed.
纳米颗粒在人类医学领域用作诊断和治疗剂已有相当长一段时间了，不过它们在兽医学和动物生产中的应用仍然相对较新。近来，由于对微生物抗生素耐药性的日益关注，畜牧业的生产需求主要集中在使用抗生素作为生长促进剂上。许多国家报告了抗生素耐药菌的发病率增加，法律法规正在更新，以终止动物生产行业中饲料中抗生素的使用。这就需要建立合适的替代品用于饲料中。许多报告已证明纳米颗粒可能是促进动物生长和抗菌的良好候选物。纳米技术在动物生产中的应用现状和进展将是本综述的重点，还将讨论纳米颗粒在营养输送、杀菌剂以及兽医学和繁殖工具方面的新作用。此外，还将综述对肉、蛋和奶质量的影响。
