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. |
