摘要： [目的]研究日粮中联合添加大豆异黄酮和胆汁酸对绿壳蛋鸡生产性能及血清生理生化指标的影响。[方法]选择72只370日龄绿壳蛋鸡,随机分为2组,每组4个重复,每个重复9只鸡。对照组蛋鸡饲喂玉米-豆粕型基础日粮,试验组蛋鸡日粮中添加12.5 mg/kg大豆异黄酮和60 mg/kg胆汁酸,预试期7 d,正试期105 d。记录每个重复蛋鸡在试验期间的采食情况、产蛋数和产蛋重量,计算平均采食量、料蛋比和产蛋率,试验结束时,采集鸡蛋样品测定鸡蛋品质指标,采集血液样品制备血清,测定血清生理生化指标。[结果]与对照组相比,试验组蛋鸡平均采食量和产蛋率分别提高11.80%和10.64%,差异显著（P<0.05）。试验组和对照组的料蛋比、蛋形指数、蛋重、蛋壳相对重和蛋黄相对重差异不显著（P>0.05）,但试验组的蛋重和蛋壳相对重有提高的趋势。试验组蛋鸡血清中乙酰胆碱酯酶（AChE）含量较对照组提高32.45%,差异显著（P<0.05）。试验组和对照组的血清总蛋白（TP）、白蛋白（ALb）、谷丙转氨酶（GPT）、谷草转氨酶（GOT）、促卵泡素（FSH）和黄体生成素（LH）差异不显著（P>0.05）,但试验组的总蛋白（TP）、白蛋白（ALb）、促卵泡素（FSH）和黄体生成素（LH）有提高的趋势,谷丙转氨酶（GPT）和谷草转氨酶（GOT）有下降的趋势。[结论]给产蛋中后期的绿壳蛋鸡日粮中联合添加12.5 mg/kg大豆异黄酮和60 mg/kg胆汁酸,可以提高蛋鸡生产性能并改善血清生化指标。

Abstract: [Objective] This study was conducted to assess the effects of dietary supplementation of soybean isoflavones and bile acids on production performance and serum physiological and biochemical indexes of green-shell laying hens. [Method] A total of 72 370-day-old green-shell laying hens were selected and randomly assigned into a control group or an experimental group, with 4 replicates in each group and 9 hens in each replicate. The control group were fed with a corn-soybean meal basal diet, while the experimental group received the same basal diet supplemented with 12.5 mg/kg soybean isoflavones and 60 mg/kg bile acids. The whole feeding experiment was consist of a 7-day preliminary trial and a 105-day formal trial. The feed intake, egg production and egg weight of each laying hen replicate during the experiment were recorded, and the average feed intake, feed to egg ratio and egg production rate were calculated. At the end of the experiment, egg samples were collected to measure egg quality indexes; blood samples were collected to prepare serum, and the serum physiological and biochemical indexes were measured. [Result] Compared with the control group, the average feed intake and egg production rate of the experimental group increased by 11.80% and 10.64%, respectively, with significant （P<0.05） differences. There were no significant （P>0.05） differences in the feed to egg ratio, egg shape index, egg weight, relative weight of eggshell, and relative weight of egg yolk between the experimental group and the control group, while there was an increasing trend in egg weight and relative weight of eggshell in the experimental group. The serum content of acetylcholinesterase （AChE） in the experimental group increased by 32.45% compared to that of the control group, with significant （P<0.05） difference. No significant （P>0.05) differences in serum contents of total protein （TP）, albumin （ALb）, glutamic pyruvic transaminase （GPT）, glutamic oxalacetic transaminase （GOT）, follicle-stimulating hormone （FSH）, and luteinizing hormone （LH） were observed between the experimental group and the control group, while increasing trends in serum contents of TP, ALb, FSH and LH as well as decreasing trends in those of GPT and GOT were observed in the experimental group. [Conclusion] Dietary supplementation of 12.5 mg/kg soybean isoflavones and 60 mg/kg bile acids for green-shell laying hens in the middle and late laying period improved the production performance and serum biochemical indexes.
