摘要
目的:本研究旨在探讨阳离子吸附型活性炭(CAAC)对鸡蛋品质及营养成分的影响,为蛋鸡饲料添加剂的合理开发与科学应用提供科学依据。方法:选取400只18周龄的京红1号蛋鸡,随机分为4个处理组。对照组饲喂基础日粮,CAAC处理组饲喂添加0.3% CAAC的基础日粮,Zn + Se处理组饲喂添加0.3 mg/kg亚硒酸钠和80 mg/kg氧化锌的基础日粮,CAAC + Zn + Se处理组饲喂同时添加0.3% CAAC、0.3 mg/kg亚硒酸钠和80 mg/kg氧化锌的基础日粮。然后分别测定鸡蛋的品质指标(蛋重、蛋黄重量、哈氏单位等)和营养成分(锌、硒、胆固醇、卵磷脂等)。结果:与对照组相比,CAAC组蛋黄重量和哈氏单位显著提升,蛋黄中锌和硒含量显著增加,胆固醇含量显著降低,卵磷脂含量显著提高。然而,与Zn + Se组相比,CAAC + Zn + Se组蛋重显著增加,而蛋黄中硒含量显著降低。结论:CAAC可显著改善鸡蛋品质和营养成分,但在与其他添加剂复合使用时可能存在相互作用。未来需进一步研究其作用机制,以优化蛋鸡饲料添加剂。
Objective: This study aims to investigate the effects of Cation Adsorbing Activated Carbon (CAAC) on egg quality and nutritional composition, providing a scientific basis for the rational development and application of feed additives in laying hens. Methods: A total of 400 18-week-old Jinghong No.1 laying hens were randomly divided into four treatment groups. The control group was fed a basal diet, the CAAC group was fed a basal diet supplemented with 0.3% CAAC, the Zn + Se group was fed a basal diet supplemented with 0.3 mg/kg sodium selenite and 80 mg/kg zinc oxide, and the CAAC + Zn + Se group was fed a basal diet supplemented with 0.3% CAAC, 0.3 mg/kg sodium selenite, and 80 mg/kg zinc oxide. Egg quality indicators (egg weight, yolk weight, Haugh unit, etc.) and nutritional components (zinc, selenium, cholesterol, lecithin, etc.) were then measured. Results: Compared with the control group, the CAAC group showed significant increases in yolk weight and Haugh unit, as well as significant increases in zinc and selenium content in the yolk. In contrast to the Zn + Se group, the CAAC + Zn + Se group showed a significant increase in egg weight, but a significant decrease in selenium content in the yolk. Conclusions: CAAC can significantly improve egg quality and nutritional composition. However, potential interactions may occur when CAAC is used in combination with other additives. Further research is needed to explore its mechanisms of action to optimize feed additives for laying hens.
