摘要： 试验旨在研究用小麦完全代替日粮中的玉米后饲喂产蛋鸡的效果，以评估小麦用作蛋鸡能量饲料的可行性。试验采用对比试验设计，选用尼克红蛋鸡180只，随机分为两个组，每组3个重复，每个重复30只蛋鸡。一组为对照组，另一组为处理组，分别饲喂玉米——豆粕型日粮和小麦——豆粕型日粮。结果表明，在蛋鸡日粮中用小麦完全代替玉米后，产蛋率降低1.9%，产蛋量降低1.06枚/只，异软蛋率提高0.09%，采食量提高1.04(g/只·d)，料蛋比提高0.09，均差异显著（p<0.05）；破蛋率提高0.33%，平均蛋重降低0.54%，但差异不显著(p>0.05)。从营养物质的消化率考虑，小麦型日粮表观能量的利用率和蛋白质的表观消化率与玉米组相比均降低了，但均差异不显著(p>0.05)。从经济效益考虑，小麦型日粮的饲料成本虽然降低了，但其他指标均不如玉米组，且产蛋成本增加了0.01元/kg。

Abstract: The trial was conducted to evaluate the possibility whether wheat could completely replace corn in the diet of laying hens. 180 laying hens were divided 2 experimented treatments, randomly, with 3 replicates and each of 30 layers. The trial adopted contrast design, treatment 1 fed with typical corn-soybean-meal diet, the other treatment fed with wheat-based diet. The results showed that the egg performance fed wheat-based diet was lower than treatment fed corn-soybean-meal diet : laying rate significantly decreased by 1.9%（p﹤0.05）, the rate of unusual shape egg and soft-shelled egg significantly increased by 0.09%（p﹤0.05）, feed to egg ratio significantly increased by 0.09（p﹤0.05）, feed intake significantly increased by 1.04%（p﹤0.05）, broken egg rate increased（p﹥0.05）, average egg weight decreased by 0.54% gram per egg（p﹥0.05）.energy utilization and protein apparent digestibility decreased without significant difference（p﹥0.05）. The feed cost in wheat-based diet reduced, but it was lower than treatment 1 in other indexes, and the egg cost of per kilogram increased by 0.01RMB.
