The effect of including sugar beet pulp (SBP) in laying hen diets on performance, egg quality, blood chemistry and egg lipid peroxidation was studied. A total of 200 laying hens were randomly assigned into 4 groups and were offered diets containing SBP at the level of 0%, 3%, 5%, and 7%. The dietary inclusion of SBP linearly (P < 0.01) increased feed intake, egg production, egg weight and mass, and improved feed conversion ratio, yolk color core and Haugh unit. Eggs laid by hens receiving SBP had linearly (P < 0.01) greater protein and lower ether extract. Dietary inclusion of SBP linearly (P < 0.01) decreased egg yolk malondialdehyde, cholesterol, and triglyceride, while increased glutathione peroxidase. Laying hens fed SBP had lower (P < 0.01) serum total lipids, cholesterol, alanine aminotransferase, aspartate aminotransferase, and creatinine. Dietary inclusion of SBP could improve hen performance, health, egg quality, and egg shelf life.
研究了在蛋鸡日粮中添加糖蜜酒精糟（SBP）对产蛋性能、蛋品质、血液生化和蛋黄脂质过氧化的影响。将 200 只蛋鸡随机分为 4 组，分别饲喂 SBP 添加水平为 0%、3%、5%和 7%的日粮。日粮中添加 SBP 线性（P < 0.01）增加了采食量、产蛋率、蛋重和蛋质量，改善了饲料转化率、蛋黄颜色核心和哈夫单位。饲喂 SBP 的母鸡所产鸡蛋的蛋白含量呈线性增加（P < 0.01），而醚提取物含量降低。日粮中添加 SBP 线性（P < 0.01）降低了蛋黄丙二醛、胆固醇和甘油三酯，同时增加了谷胱甘肽过氧化物酶。饲喂 SBP 的蛋鸡血清总脂、胆固醇、丙氨酸氨基转移酶、天冬氨酸氨基转移酶和肌酐水平降低（P < 0.01）。日粮中添加 SBP 可以改善母鸡的生产性能、健康状况、蛋品质和蛋的货架期。
