关于使用人类抗生素促进食用动物生长的争议仍然存在。作者研究了去除用于促进商品肉鸡生长的抗生素的经济影响。作者利用美国第四大家禽生产商Perdue公司发布的数据，其中一项关于促生长抗生素（GPA）的非随机对照试验使用700万只肉鸡来评估去除GPA对生产的影响。GPA的使用，但不足以抵消抗生素的成本。使用GPA的净效应是每只鸡损失价值0.0093美元（约占总成本的0.45%）。根据这些数据，作者发现没有任何依据来证明使用GPA可以降低生产成本。请注意，本研究不包括兽医成本变化或与去除GPA相关的性能变化。本经济分析是作者所知的第一项利用美国工业收集的大规模经验数据的研究，其中证明了在家禽生产中使用GPA与生产者的经济损失有关。这些数据在持续进行的关于继续使用抗生素促进食用动物生长的全国性辩论中具有相当重要的意义。根据行业研究和由此产生的经济影响，应重新考虑在美国家禽生产中使用GPA。
Considerable controversy persists regarding the use of human antibiotics to promote growth in animals raised for food. The authors examined the economic effect of removing antibiotics used for growth promotion in commercial broiler chickens.The authors utilized data published by the Perdue company, the fourth largest poultry producer in the United States, in which a non-randomized controlled trial of growth-promoting antibiotic (GPA) use was conducted with seven million broiler chickens to evaluate the impact of removing GPAs on production.Positive production changes were associated with GPA use, but were insufficient to offset the cost of the antibiotics. The net effect of using GPAs was a lost value of $0.0093 per chicken (about 0.45% of total cost). Based upon these data, the authors found no basis for the claim that the use of GPAs lowers the cost of production. Note that this study does not include veterinary cost changes or changes in performance variability associated with the removal of GPAs.This economic analysis is the first study to the authors' knowledge utilizing large-scale empirical data collected by U.S. industry, in which it is demonstrated that the use of GPAs in poultry production is associated with economic losses to the producers. These data are of considerable importance in the ongoing national debate concerning the continued use of antibiotics for growth promotion of food animals. Based on the industry study and the resulting economic impact, the use of GPAs in U.S. poultry production should be reconsidered.
