基　　金：Supported by Core Pure Population Breeding and Industry Demonstration Base Construction of Changshun Green-shell Layer(QNYZ[2011]027);Association Study of PRL Gene and PRLR Gene Polymorphisms of Changshun Greenshell Layer with Egg Production Traits(QKHJ[2011]2174) 摘　　要：To explore the effect of different additive combinations on double-low rapeseed cake( meal) utilization and layer production performance,we randomly divided 756 Roman brown shell layers around 50 weeks age into seven groups to detect production performance,of which group 1 was control group supplied with basic diet( added with 9% double-low rapeseed cake),while groups 2- 7 were experimental groups added with Chinese herbal medicine,enzyme preparation,probiotics and peptide antibiotics in basic diet. The results showed that group 4 added with Chinese herbal medicine + enzyme preparation + peptide antibiotics received the best effect,resulting in significantly increased laying rate( 70. 50%,P < 0. 05),significantly reduced feed-egg ratio( 2. 46,P < 0. 05),and extremely increased egg Haugh unit( P < 0. 01). This indicated that adding combination of Chinese herbal medicine + enzyme preparation + peptide antibiotics in layer basic diet could improve egg production performance and egg quality of layers. 关键词：生产性能褐壳蛋鸡添加剂双低菜籽饼肽抗生素酶制剂利用效果哈夫单位
