摘　　要：试验旨在研究甜叶菊绿原酸和染料木素对产蛋后期海兰褐蛋鸡生产性能、蛋品质、卵泡发育和抗氧化性能的影响。试验选取360只体重相近且健康的70周龄海兰褐蛋鸡,按生产性能无显著差异的原则分为4组(P>0.05),每组6个重复,每个重复15只鸡。对照组饲喂基础日粮,试验组分别饲喂基础日粮+120 mg/kg绿原酸(绿原酸组)、基础日粮+120 mg/kg染料木素(染料木素组)、基础日粮+120 mg/kg绿原酸+120 mg/kg染料木素(绿原酸+染料木素组)。试验预饲期2周,正试期12周。结果显示:绿原酸、染料木素或二者共同添加对蛋鸡生产性能无显著影响(P>0.05)。与对照组相比,绿原酸、染料木素单独和共同添加均显著提高蛋鸡蛋壳强度、蛋壳厚度(P<0.05);绿原酸、染料木素单独添加显著提高蛋鸡蛋壳比例(P<0.05);绿原酸、绿原酸与染料木素共同添加显著降低蛋鸡蛋壳颜色L^(*)值,显著提高蛋壳颜色a^(*)值(P<0.05)。与对照组相比,绿原酸、染料木素或二者共同添加对蛋鸡卵泡数量、卵泡重量和卵泡指数无显著影响(P>0.05)。与对照组相比,绿原酸、绿原酸与染料木素共同添加显著提高蛋鸡肝脏超氧化物歧化酶活性(P<0.05);绿原酸显著提高卵巢总抗氧化能力(P<0.05)。研究提示:绿原酸和染料木素虽然未显著提高产蛋后期蛋鸡生产性能,但可显著改善蛋壳质量,同时增强肝脏和卵巢的抗氧化功能。The study aimed to investigate the effects of Stevia chlorogenic acid and genistein on production performance,egg quality,follicle development and antioxidant performance of Hy-Line Brown layers in late laying period.A total of 360 healthy 70-week-age Hy-Line Brown layers with similar body weight were selected and randomly assigned to four groups with no significant differences in production performance(P>0.05).Each group included six replicates,with 15 chickens per replicate.The control group was fed a basal diet,while the treatment groups received the basal diet supplemented with 120 mg/kg chlorogenic acid(chlorogenic acid group),120 mg/kg genistein(genistein group)and 120 mg/kg chlorogenic acid combined with 120 mg/kg genistein(chlorogenic acid+genistein group).The trial lasted for 14 weeks,comprising a 2-week pre-feeding period and a 12-week experimental period.The results showed that the addition of chlorogenic acid,genistein or their combination had no significant impact on production performance of laying hens(P>0.05).However,compared with the control group,both chlorogenic acid and genistein,either individually or in combination,significantly improved eggshell strength and thickness of laying hens(P<0.05),with chlorogenic acid and genistein alone significantly increasing the eggshell ratio of laying hens(P<0.05).Additionally,chlorogenic acid,either alone or combined with genistein,significantly reduced the eggshell color L^(*)value while increasing the a^(*)value of laying hens(P<0.05),the supplementation of which had no significant effect on ovarian index,follicle weight,or number of laying hens(P>0.05).Furthermore,chlorogenic acid,either alone or in combination with genistein,significantly increased hepatic superoxide dismutase content of laying hens(P<0.05),while chlorogenic acid alone significantly enhanced the total antioxidant capacity of the ovaries of laying hens(P<0.05).In conclusion,although chlorogenic acid and genistein supplementation did not significantly improve the production performance o
