ABSTRACT The experiment was conducted to study the effectiveness of dried milky sludge (DMS) as a feed source for laying Japanese quails. The DMS was incorporated into the experimental diets at levels of 0, 5.0, 10.0, 15.0 and 20.0%. Four hundred quails were used in a completely randomized design. The results revealed that the daily egg-laying rate, feed cost/100 egg weight, egg width, egg length, egg weight, shell quality characteristics in terms of breaking time, Young's modulus, work, max force, fracturability, breaking stress, stiffness and power, as well as color intensity and yolk height improved significantly with increasing levels of DMS in the diet (P < 0.05), while feed intake/bird/day, mortality and eggshell thickness showed no significant differences (P > 0.05). From this experiment, it was found that DMS incorporated into the experimental diet at the 20.0% level yielded the most productive performance and best egg quality.
摘要 本实验旨在研究干奶渣（DMS）作为产蛋鹌鹑饲料来源的效果。将 DMS 以 0、5.0、10.0、15.0 和 20.0%的水平添加到实验日粮中。采用完全随机设计，使用 400 只鹌鹑。结果表明，随着日粮中 DMS 水平的增加，每日产蛋率、饲料成本/每 100 枚蛋重、蛋宽、蛋长、蛋重、蛋壳质量特性（破壳时间、杨氏模量、功、最大力、易碎性、破壳应力、硬度和功率）以及颜色强度和蛋黄高度显著提高（P < 0.05），而采食量/只/天、死亡率和蛋壳厚度无显著差异（P > 0.05）。本实验发现，实验日粮中添加 20.0%的 DMS 可获得最佳产蛋性能和最佳蛋品质。
