摘　　要：本研究根据蛋鸡的生物学特点和行为学习性,在舍内配置栖木、采食底网、料线、水线及产蛋箱等规模饲养设施,构建了栖架舍饲散养模式,围绕其对蛋鸡生产性能、蛋品质与免疫机能的影响,进行了初步的应用研究。结果表明,栖架散养组开产时间推迟3周,但其平均料蛋比下降了9.05%,平均蛋重、平均产蛋率较对照组分别提高了2.62%、3.45%;栖架舍饲散养组的蛋白高度、哈氏单位、蛋形指数均显著高于对照组(P<0.05),分别提高了24.13%、8.03%、6.35%;栖架舍饲散养组的胸腺指数、脾脏指数、法氏囊指数、鸡新城疫抗体效价较对照组分别提高了5.44%、3.48%、6.57%、16.74%。综上所述,栖架舍饲散养模式有助于降低蛋鸡料蛋比,改善蛋品质,促进免疫机能的提高,体现了福利化健康养殖的需要。In order to investigate the effect of layer housing range model with perches on production performance, egg quality and immune function of laying hens, basing on the layer＇s biological characteristics and behavior habits, the study initially constructed a feeding model which consists of perches, bottom web, feeding, drinking, and laying nest. The results showed that compared with control group, the age of producing first egg of the perches model could be delayed by 3 weeks and the feed-egg ratio of laying period reduced by 9.05%. At the meantime, the average egg weight and laying rate were increased by 2. 62% and 3. 45 % ,respectively. The protein height, hunt unit and egg shape index of experiment group were significantly higher than that of control group （P〈0. 05） , higher above 24. 13 % ,8.03 % and 6. 35 % ,respectively. The indexes of thymus, spleen, bursa and the antibody titer of Newcastle were increased by 5. 44 % ,3.48 % ,6.57 % and 16. 74% of experiment group than that of control group, respectively. In conclusion, the housing range model with perches could not only reduce the feed-egg ratio but also improve the egg quality and immune function of laying hens.
