Antibiotic feed additives are frequently added to animal diets at subtherapeutic dosages in order to boost feed conversion and accelerate growth. These growth promoters can potentially to compromise the therapeutic efficacy of antimicrobial agents used in humans and animals by fostering the emergence and spread of antibiotic-resistant genes. Consumers are becoming more aware of the harmful consequences of bacteria that are resistant to antibiotics. There is a growing body of research on substitute growth promoters; at the moment, the goals are to increase growth rates and decrease the use of veterinary antibiotics in agriculture. Potential substitutes for antibiotic feed additives include phytogenic feed additives and compounds derived from plants. Phytogenic feed additives (PFA) including herbs, spices, essential oils and other plant extracts enhances zootechnical and animal health parameters, lowers emissions of ammonia and odors, enhances the utilization of amino acids and nutrients, and improves the quality of the carcass and meat. This review examines how phytogenic feed additives supplementation affects animal product quality and acceptability by consumers.
抗生素饲料添加剂经常以亚治疗剂量添加到动物日粮中，以提高饲料转化率并加速生长。这些生长促进剂可能会通过促进抗生素抗性基因的出现和传播，损害人类和动物使用的抗菌剂的治疗效果。消费者越来越意识到对抗生素耐药细菌的有害后果。关于替代生长促进剂的研究越来越多；目前的目标是提高生长速度并减少农业中兽医抗生素的使用。抗生素饲料添加剂的潜在替代品包括植物源饲料添加剂和源自植物的化合物。植物源饲料添加剂（PFA），包括草药、香料、精油和其他植物提取物，可提高畜牧技术和动物健康参数，降低氨和气味排放，提高氨基酸和营养物质的利用率，并改善胴体和肉类质量。本综述探讨了添加植物源饲料添加剂如何影响动物产品质量和消费者的接受度。
