The study evaluated whether including pepper, cashew nut, and copaiba essential oils blend (EOB) in broiler feed positively influences performance and nutrient metabolizability. Birds of the Cobb® lineage were distributed in a completely randomized design in a factorial scheme (2 × 2 + 1), with five treatments: a control diet (Control) with antibiotic growth promoter (AGP); a diet without AGP with 300 g/t of EOB (EOB 300), a diet without AGP with 500 g/t of EOB (EOB 500), a diet with synergy between AGP and 300 g/t of EOB (Sy 300), and a diet with synergy between AGP and 500 g/t of EOB (Sy 500). The results indicated that the treatment with 300 g/t of EOB, with or without AGP, provided better feed conversion ratio and metabolizability coefficients of crude protein, ether extract, and ash. In conclusion, the phytogenic additive based on essential oils can be an alternative to replace antibiotic growth promoter, as its inclusion provides better zootechnical performance and nutrient metabolizability in broiler production.
该研究评估了在肉鸡饲料中添加辣椒、腰果和 Copaiba 精油混合物（EOB）是否会对生产性能和养分代谢率产生积极影响。科宝®品系的鸡只采用完全随机设计，按析因方案（2×2 + 1）进行分组，共有五种处理方式：一种添加抗生素生长促进剂（AGP）的对照日粮（对照）；一种不添加 AGP 但添加 300 g/t EOB 的日粮（EOB 300），一种不添加 AGP 但添加 500 g/t EOB 的日粮（EOB 500），一种 AGP 与 300 g/t EOB 协同作用的日粮（Sy 300），以及一种 AGP 与 500 g/t EOB 协同作用的日粮（Sy 500）。结果表明，添加 300 g/t EOB 的处理方式，无论是否添加 AGP，均能提供更好的饲料转化率以及粗蛋白、乙醚提取物和灰分的代谢率系数。总之，基于精油的植物源添加剂可作为替代抗生素生长促进剂的选择，因为在肉鸡生产中添加该添加剂可提供更好的畜牧生产性能和养分代谢率。
