Abstract：
This study was conducted to investigate the effect of dietary supplementation of octacosanol (OCT) extracted from triticale sprout on laying performance, egg quality, and blood parameters of laying hens. A total of 192, Hyline brown laying hens aged 43 weeks were divided into 4 dietary groups of 48 birds each and they were randomly subjected to one of the experimental diets containing OCT at the levels of none, 10, 20, and 30 mg/kg of diet. All birds were fed with isoenergetic and isonitrogenous mash diets for 6 weeks. The result showed that hens supplemented with 20 and 30 mg/kg OCT in diet significantly increased (p < 0.05) egg production than those fed with the basal diet. OCT concentration in the egg yolk of hens fed with 20 and 30 mg/kg OCT was significantly higher than in those fed the control diet. Hens fed 20 and 30 mg/kg OCT exhibited greater high-density lipoprotein (HDL) cholesterol and interleukin (IL) concentrations and reduced serum concentrations of cholesterol and triglyceride compared to those fed with 0 and 10 mg/kg OCT. This study indicates that supplementing the diet of laying hens with 20 and 30 mg/kg of OCT can improve the performance, egg quality, and health status of laying hens.
摘要：
本研究旨在研究饲粮中添加从小黑麦芽中提取的二十八烷醇（OCT）对产蛋性能的影响。鸡蛋质量,和蛋鸡的血液参数。将总共192只43周龄的Hyline棕色蛋鸡分为4个饮食组，每组48只，随机接受含有OCT的实验饮食之一，10、20和30mg/kg日粮。所有鸟类均饲喂等能量和等氮糊状饲料6周。结果表明，饲粮中添加20和30mg/kgOCT的母鸡比基础饲粮显著提高了产蛋量（p<0.05）。饲喂20和30mg/kgOCT的蛋黄中的OCT浓度明显高于饲喂对照饮食的蛋黄中的OCT浓度。与饲喂0和10mg/kgOCT的母鸡相比，饲喂20和30mg/kgOCT的母鸡表现出更高的高密度脂蛋白（HDL）胆固醇和白介素（IL）浓度以及降低的胆固醇和甘油三酸酯血清浓度。本研究表明，在蛋鸡日粮中添加20和30mg/kg的OCT可以改善蛋鸡的生产性能，鸡蛋质量,和蛋鸡的健康状况。
