This study evaluated the production performance and egg quality of Lohmann Brown laying hens fed diets containing different levels of Corn Bran with Solubles (CBS). A total of 144 hens aged 44 weeks were assigned to three treatments in a completely randomized design, with eight replicates per treatment and six birds per replicate. The experimental treatments included diets with CBS inclusion levels of 0%, 5%, and 10%. The experiment lasted 84 days (44 to 55 weeks of age). Data were analyzed via one-way ANOVA, with mean differences evaluated using Tukey's HSD test (α = 0.05). No significant effects were observed for laying rate, feed intake, feed conversion ratio, or egg mass ( > 0.05). However, egg quality parameters such as shell percentage, shell weight per unit surface area (SWUSA), and yolk color were influenced by the treatments ( < 0.05). Hens fed diets with 5% CBS exhibited higher shell percentage and SWUSA compared to those on the 0% CBS diet. Yolk color intensity increased with higher CBS inclusion levels. In conclusion, incorporating up to 10% CBS in corn-soybean meal diets for laying hens can enhance egg yolk pigmentation. Notably, including 5% CBS improves eggshell quality.
本研究评估了饲喂不同水平含可溶物玉米麸(CBS)日粮的罗曼褐蛋鸡的生产性能和蛋品质。总共144只44周龄的母鸡被完全随机分配到三种处理中,每个处理有8个重复,每个重复6只鸡。实验处理包括CBS添加水平为0%、5%和10%的日粮。实验持续84天(44至55周龄)。数据通过单因素方差分析进行分析,均值差异使用Tukey's HSD检验进行评估(α = 0.05)。产蛋率、采食量、饲料转化率或蛋重均未观察到显著影响(P>0.05)。然而,蛋壳比例、单位表面积蛋壳重量(SWUSA)和蛋黄颜色等蛋品质参数受到处理的影响(P<0.05)。与饲喂0% CBS日粮的母鸡相比,饲喂5% CBS日粮的母鸡表现出更高的蛋壳比例和SWUSA。蛋黄颜色强度随着CBS添加水平的提高而增加。总之,在蛋鸡的玉米-豆粕日粮中添加高达10%的CBS可以增强蛋黄色素沉着。值得注意的是,添加5%的CBS可改善蛋壳质量。
