To study the effects of antibacterial peptides (ABPs) on feeding broilers, this experiment compared the 2 combinations of ABP with antibiotics by separately adding the supplement to the diet of 818 broilers as follows-antibiotics, Pratt and Full-tide, and Pratt and plant essential oil-and then the effect of them on production performance, immune function, antioxidant capacity, serum biochemical indicators, and microorganisms of the experimental flocks was investigated and compared. It was found that the aforementioned indicators among the 2 groups of ABP and the antibiotic group were close to or even better than those of antibiotics, and the combination added with plant essential oils had generally better effects. These results indicated that ABPs could improve economic benefits by promoting growth, preventing disease, and reducing the rate of death. This study deepened the research on the action mechanism of ABPs and not only explored the feasibility of ABPs as a novel feed additive for broilers but also provided experimental data and theoretical basis for the application of ABPs.
为研究抗菌肽（ABPs）对肉仔鸡的影响，本试验通过在 818 羽肉仔鸡的日粮中分别添加抗生素 Pratt 和 Full-tide、抗生素 Pratt 和植物精油这 2 种 ABPs 组合，与抗生素进行对比，研究比较了它们对试验鸡群生产性能、免疫功能、抗氧化能力、血清生化指标和微生物的影响。结果表明，2 组 ABPs 与抗生素组的上述指标均接近或优于抗生素，且添加植物精油的组合效果普遍更好。这些结果表明，ABPs 可以通过促进生长、预防疾病和降低死亡率来提高经济效益。本研究深化了 ABPs 作用机制的研究，不仅探索了 ABPs 作为新型肉仔鸡饲料添加剂的可行性，还为 ABPs 的应用提供了实验数据和理论基础。
