抗生素是在50多年前被发现的，并从那时起被广泛用于牲畜和家禽业。它们是高效生产猪肉、牛肉、禽肉和其他动物产品的极其重要的工具。当在饲料中使用低（亚治疗）水平的抗生素时，可提高生长速度和饲料利用效率，降低死亡率和发病率，并提高繁殖性能。抗生素也用于预防疾病的中级水平和用于治疗动物疾病的高（治疗）水平。
Antibiotics were discovered over 50 years ago and have since been widely used in the livestock and poultry industries. They represent an extremely important tool in the efficient production of pork, beef, poultry meat, and other animal products. When used at low (subtherapeutic) levels in feeds, antibiotics improve growth rate and efficiency of feed utilization, reduce mortality and morbidity, and improve reproductive performance. Antibiotics are also used at intermediate levels to prevent disease and at high (therapeutic) levels to treat diseases in animals.
