摘　　要：试验选用28周龄产蛋率接近的健康苏禽绿壳蛋鸡720只,随机分为6个处理,每个处理6个重复,每个重复20只,试验饲粮分别含有0(对照组)、1%、3%、5%、7%和9%的玉米DDGS,试验期12周。结果表明:1蛋黄颜色受玉米DDGS影响显著(P<0.05,线性P<0.05),随着玉米DDGS含量的增加显著增加。2血清胆固醇和甘油三酯含量受玉米DDGS的影响显著(P<0.05),与玉米DDGS含量均呈显著二次曲线关系(P<0.05),饲粮玉米DDGS含量分别为6.02%和5.63%时,蛋鸡血清胆固醇和甘油三酯含量最低。3试验期内,与对照组相比较,1%、3%、5%、7%和9%玉米DDGS组饲粮成本分别降低了0.156、0.367、0.841、0.532、0.686元/只,7%和9%玉米DDGS组的利润分别增加了0.292、0.854元/只。由此可见,饲粮不同玉米DDGS水平对蛋鸡产蛋性能、蛋品质和蛋黄胆固醇含量无不良影响;蛋黄颜色随着玉米DDGS含量的增加显著增加,添加7%和9%玉米DDGS能够显著提高蛋黄颜色等级,有效增加生产利润;饲粮玉米DDGS对蛋鸡血清胆固醇和甘油三酯含量的建议值分别为6.02%和5.63%。An experiment was conducted to study the effects of dietary corn distillers dried grains with solubles （DDGS） level on laying performance, egg quality, serum lipids indices, and economic profit of laying hens, and aimed to research the appropriate addition of corn DDGS in diets for laying hens. Seven hundred and twenty 28-week-old Suqin green-shelled laying hens with similar laying rate were assigned to 6 groups with 6 replicates in each group and 20 hens per replicate. Experimental diets contained 0 （control group）, 1%, 3%, 5%, 7% and 9% DDGS. The experiment lasted for 12 weeks. Resuits showed as follows： （1） the yolk color was significantly affected by corn DDGS （P〈0.05）, and the yolk color increased as the level of dietary corn DDGS increased （P〈0.05）. （2） The serum cholesterol and triglyceride content in corn DDGS groups was significantly affected by corn DDGS （P〈0.05）, and there were significant quadratic correlations between serum cholesterol, triglyceride content and corn DDGS content （P〈0.05）. The corn DDGS content in the diet of laying hens during the period for the lowest serum cholesterol and triglyceride content were 6,02% and 5.63%. （3） In the experiment, compared with the control group, the feed cost in 1%, 3%, 5%, 7% and 9% corn DDGS groups was reduced by 0.156, 0.367, 0.841, 0.532, 0.686 yuan per bird, and the profit in 7% and 9% corn DDGS groups was increased by 0.292, 0,854 yuan per bird. It is indicated that corn DDGS has no harmful el[eels on laying performance, egg quality anti yolk cholesterol content. The yolk color increase as the level of dietary eorn DDGS inerease, and 7% and 9% DDGS signitlcantly increase the yolk color, and can effectively increase the profit. The recommended values of corn I）DGS content are 6.02% and 5.63% for the lowest serum cholesterol and triglyceride content, respeclively.
