In this study, a total of 312 Hyline brown laying hen of 1.92 ± 0.12 kg acquired at 24-wk old were employed to evaluate the pharmaceutical effect of Korean wild ginseng residue extract administered via drinking water on the performance, microbiota quality, cytokine expression, and the ginsenoside saponin (GS) content of laying hen for 12 wk. In the experiments, basic feed (CON) was compared with basic feed + 0.05% wild ginseng in drinking water (WGD1), basic feed + 0.1% wild ginseng in drinking water (WGD2), and basic feed + 0.5% wild ginseng in drinking water (WGD3). At the end of study, hen-day egg production (HDEP), average egg weight (AEW), and egg mass (EM) were linearly higher (p < 0.05) in WGD3 at wk 30 to 33, 34 to 37 wk, and the cumulative wk compared with CON. Feed conversion ratio (FCR) was linearly lower in WGD3 at 34 to 37 wk, and the cumulative wk compared with CON. Relative expression of tumor necrosis factor alpha (TNF-α) was linearly lower (p < 0.05) in the WGD3 at wk 30 to 33, and 34 to 37 wk compared with CON. The GS in egg yolk was linearly higher (p < 0.05) in laying hens supplemented the WGD3 treatment at wk 34 to 37, while the fecal microflora quantity of Lactobacillus was linearly higher (p < 0.05) in WGD3 at wk 30 to 33, till 34 to 37 wk, and Escherichia coli (E. coli) was linearly lower (p < 0.05) in the WGD2 and WGD3 from 2637 wk compared with CON. We concluded the result in HDEP, AEW, EM, and FCR were due to the increase in GS content, tentatively leading to an improvement in the TNF-α, and fecal microflora quality such as Lactobacillus and E. coli in the WGD3. We therefore recommend the use of WGD3 at application level 0.5% in drinking water for optimum laying performance from 30 to 37 wk.
在这项研究中，共使用了 312 只 1.92 ± 0.12 公斤重的海兰褐蛋鸡，这些鸡在 24 周龄时被采集，用于评估通过饮用水给药的高丽野山参残渣提取物对产蛋鸡 12 周的性能、微生物群质量、细胞因子表达和人参皂甙（GS）含量的药物作用。在实验中，基础饲料（CON）与基础饲料+ 0.05%野山参在饮用水中（WGD1）、基础饲料+ 0.1%野山参在饮用水中（WGD2）和基础饲料+ 0.5%野山参在饮用水中（WGD3）进行了比较。在研究结束时，母鸡日产蛋量（HDEP）、平均蛋重（AEW）和蛋重（EM）在第 30 至 33 周、第 34 至 37 周和累积周的 WGD3 中呈线性升高（p<0.05），与 CON 相比。第 34 至 37 周和累积周的 WGD3 中饲料转化率（FCR）呈线性降低。第 30 至 33 周和第 34 至 37 周的 WGD3 中肿瘤坏死因子-α（TNF-α）的相对表达呈线性降低（p<0.05）。第 34 至 37 周的 WGD3 中蛋黄中 GS 的含量呈线性升高（p<0.05），而 WGD3 在第 30 至 33 周、第 34 至 37 周的粪便微生物数量中乳酸菌呈线性升高（p<0.05），大肠杆菌（E. coli）则呈线性降低（p<0.05）。与 CON 相比，WGD2 和 WGD3 从 26 到 37 周。我们得出的结果是，HDEP、AEW、EM 和 FCR 的增加归因于 GS 含量的增加，这可能导致 TNF-α的改善，以及 WGD3 中乳酸菌和大肠杆菌等粪便微生物群质量的改善。因此，我们建议在饮用水中使用 WGD3 的应用水平为 0.5%，以在 30 至 37 周期间获得最佳产蛋性能。
