摘　　要：试验旨在研究饲料中添加复合有机微量元素对矮小型父母代种鸡产蛋性能和种蛋蛋品质的影响。1 200只生产性能接近的60周龄"农大3号"父母代种鸡随机分为2组(对照组和试验组),每组6个重复,每个重复100只鸡。对照组饲喂基础饲粮,试验组在基础日粮中添加0.05%复合有机微量元素。试验期4周。结果显示,饲料中添加复合有机微量元素能提高矮小型父母代种鸡的产蛋率、蛋壳厚度、蛋白高度和哈氏单位,降低种蛋重(P<0.05);对破蛋率、裂纹蛋率和蛋壳强度无显著影响(P>0.05)。综上,矮小型父母代种鸡饲料中添加0.05%复合有机微量元素能显著提高种鸡产蛋率和蛋品质。The objective of this experiment was to study the effects of organic trace elements on laying performance and egg quality of dwarf parent stock layers. In this experiment, 1 200 sixty-week-age "Nongda No. 3" parent stock layes with same production performance were randomly divided into the control group and experimental group with6 replicates per group and 100 chickens per replicate. The control group was fed with basal diet and the experimental group was fed with 0.05% complex organic trace elements supplimented in basal diet. The experiment lasted for four weeks. The results showed that supplementation of complex organic trace elements could significantly increase the laying rate, egg weight, shell thickness, protein height and Haugh unit of eggs(P<0.05), and reduce egg weight(P<0.05). There were no significant effects on breaking rate, cracking rate and eggshell strength(P>0.05). In conclusion,dietary 0.05% complex organic trace elements could significantly improve the laying rate and egg quality of dwarf parent stock layers.
