An experiment was conducted to determine the effect of a phytogenic compound (Alquernat Nebsui L [ANL]) applied through drinking water on hen day egg production (HDEP), egg quality, and small intestine histomorphology of Hy-Line W-36 laying hens from 65 to 73 wk of age. A total of 90 hens were randomly allocated into 2 treatment groups with 15 replicate cages, and each cage containing 3 hens. Hens were housed in an A-frame conventional cage and followed the light regime of 16L:8D period. The 2 treatments consisted of either without or with ANL provided via drinking water (0.5 mL/L) as control (CON) and ANL group. Hen day egg production, feed intake (FI), feed conversion ratio (FCR), and egg quality were measured weekly. Supplementation of ANL increased HDEP and decreased FI and FCR in the treated group. The internal quality of eggs Haugh unit (HU), total yolk carotenoids (TYC), and yolk color score (YCS) were significantly increased in the ANL group compared with the CON group. No significant differences were observed in the measured exterior quality of eggs among the 2 treatments. Alquernat Nebsui L did not affect the histomorphology of duodenum, jejunum, and ileum except for the villus width of the duodenum, which was higher in the ANL group than the CON group. There was no significant difference in either absolute or relative intestinal weight in the ANL or CON group. It can be concluded that the addition of ANL in drinking water may have beneficial effects on egg production, FI, FCR, HU, TYC, and YCS.

进行了一项实验，以确定通过饮用水施用的一种植物性化合物（Alquernat Nebsui L [ ANL ]）对Hy-Line W-36产蛋母鸡产蛋日产蛋量（HDEP），蛋品质和小肠组织形态的影响。 65至73周龄。将总共​​90只母鸡随机分为2个治疗组，每组15个重复的笼子，每个笼子中包含3只母鸡。将母鸡关在一个A形的常规笼子中，并遵循16L：8D光照条件。这两种治疗方法包括不使用或通过饮用水（0.5 mL / L）提供ANL作为对照组（CON）和ANL组。母鸡一天的产蛋量，采食量（FI），饲料转化率（FCR），并每周测量一次鸡蛋质量。在治疗组中，补充ANL可以增加HDEP，降低FI和FCR。鸡蛋的内部质量Haugh单位（HU），总卵黄类胡萝卜素（TYC）和卵黄颜色评分（YCS与CON组相比，ANL组的）明显增加。在两种处理之间，测得的鸡蛋外观质量没有显着差异。Alquernat Nebsui L除了十二指肠的绒毛宽度（在ANL组中比CON组高）以外，不影响十二指肠，空肠和回肠的组织形态。ANL或CON组的绝对或相对肠道重量均无显着差异。可以得出结论，在饮用水中添加ANL可能对产蛋量，FI，FCR，HU，TYC和YCS产生有益影响。
