Natural antibiotic substitutes have recently been used as growth promoters and to combat pathogens. Therefore, this study aimed to assess the effects of adding Magic oil (nano-emulsified plant oil) at different growing periods on growth performance, histomorphology of the ileum, carcass traits, and blood biochemistry of broiler chickens. A total of 432-day-old Ross 308 chicks were randomly assigned to 1 of 6 water supplementation treatment groups based on growing periods, with 4 groups of Magic oil programs compared to probiotic (Albovit) as a positive control and nonsupplemented group as a negative control, with 9 replicates each with 8 birds (4♂ and 4♀). The periods of adding Magic oil Magic oil were 35, 20, 23, and 19 d for T1, T2, T3, and T4, respectively. Birds' performance was evaluated during 0 to 4, 4 to 14, 21 to 30, 30 to 35, and overall days old. Carcass parameters, blood chemistry, and ileal histomorphology were examined on d 35. The findings showed that birds in the T4 group of the Magic oil supplementation program (from 1 to 4 and 21 to 35 d of age) consumed 1.82% and 4.20% more food, gained 3.08% and 6.21% more, and converted feed to meat 1.39% and 2.07% more than Albovit and negative control, respectively, during the experiment (1-35). Magic oil particularly T1 (Magic oil is supplemented throughout the growing period) and T4 programs improved intestinal histology compared to the negative control. There were no changes (P > 0.05) between treatments in carcass parameters and blood biochemistry. In conclusion, water supplementation with Magic oil for broilers improves intestinal morphometrics and growth performance similar to or better than probiotic, especially during brooding and overall periods. Further studies are needed to evaluate the effect of adding both nano-emulsified plant oil and probiotics on different parameters.
天然抗生素替代品最近被用作生长促进剂和抗病原体。因此，本研究旨在评估在不同生长阶段添加 Magic oil（纳米乳化植物油）对肉鸡生长性能、回肠组织形态、胴体特性和血液生化的影响。将 432 日龄的 Ross 308 雏鸡随机分为 6 个水补充处理组中的 1 组，根据生长阶段，将 Magic oil 程序与益生菌（Albovit）进行比较，作为阳性对照，不补充组作为阴性对照，每组 9 个重复，每个重复 8 只鸡（4♂和 4♀）。添加 Magic oil 的时间分别为 T1、T2、T3 和 T4 组的 35、20、23 和 19 d。在 0 至 4、4 至 14、21 至 30、30 至 35 和总日龄期间评估鸡的性能。在第 35 天检查胴体参数、血液化学和回肠组织形态学。结果表明，在 Magic oil 补充计划的 T4 组（1 至 4 天和 21 至 35 天龄）中，与 Albovit 和阴性对照组相比，鸡在实验期间（1-35）分别多消耗 1.82%和 4.20%的饲料，多增重 3.08%和 6.21%，饲料转化为肉的比例分别多 1.39%和 2.07%。Magic oil 特别是 T1（整个生长期补充 Magic oil）和 T4 计划与阴性对照组相比，改善了肠道组织学。在胴体参数和血液生化方面，各处理组之间没有变化（P > 0.05）。综上所述，向肉鸡饮用水中添加 Magic oil 可改善肠道形态计量和生长性能，与益生菌相似或优于益生菌，特别是在育雏期和总生长期。需要进一步研究来评估添加纳米乳化植物油和益生菌对不同参数的影响。
