【目的】为掌握培育的地方特色蛋鸡配套系生产性能和环境适应性。【方法】本试验比较笼养和平养两种饲养方式下两个配套组合（SD1HS2、HS1HS2）的存活率、蛋品质、各周龄体重和产蛋率等性能。【结果】从第8周龄开始SD1HS2公鸡体重显著高于 HS1HS2公鸡体重（P＜0．05）；从第6周龄开始，两种饲养条件下的SD1HS2母鸡体重均显著高于 HS1 HS2母鸡体重（P＜0．05）。两种饲养方式下，SD1 HS2存活率及蛋黄比例均高于 HS1 HS2（P＜0．05），而 HS1HS2的产蛋量及蛋白高度则高于 SD1HS2（P＜0．05）；同时两群体鸡平养存活率均高于笼养（P＜0．05），而它们的产蛋量以及蛋白高度则是笼养优于平养（P＜0．05）；笼养条件下的 HS1HS2组合在产蛋量及蛋白高度上均显著优于其他组合。【结论】笼养条件下两群体鸡产蛋量和蛋白高度高于平养。两群体中，HS1 HS2的产蛋率和蛋品质优于SD1 HS2。笼养是比较适合两个培育品种的饲养方式。

Obj ective]To evaluate the performance and environmental adaptability of cultivated layer lines.[Method]We measured the livability,egg quality,weekly body weight,and laying rate of two crosses (SD1HS2 and HS1HS2)raised by two housing systems the pen and cage,re-spectively.[Results]From 8 week-old,males of SD1 HS2 were heavier than HS1 HS2 in body weight (P<0. 05);from 6 week-old,the females body weight of SD1HS2 in the two housing sys-tems were heavier than that of HS1 HS2 (P<0. 05 ).In the two housing systems,the livability and yolk percentage of SD1 HS2 were higher than that of HS1 HS2 (P<0. 05 ),whereas its egg production and protein concentration were higher than those of SD1HS2 (P<0. 05).The livabili-ty of penned birds were higher than that of caged (P<0. 05 ).The egg production and protein concentration of caged birds were higher than those of penned birds (P<0. 05).The egg produc-tion and protein concentration of caged HS1 HS2 were higher than those of SD1 HS2 .[Conclu-sion]The results suggested that the egg production and albumen height of the caged layers,no matter from cross SD1 HS2 or HS1 HS2 were superior to the penned chickens.The laying rate and egg quality of HS1 HS2 were higher than those of SD1 HS2 .The cage housing system is fit for our two crosses.
