摘　　要：为了评估发酵五子衍宗方对产蛋后期罗曼蛋鸡的影响,设置5组试验,对照组饲喂基础日粮,试验组分别饲喂在基础日粮中添加0.50%未发酵五子衍宗方和0.25%、0.50%、0.75%的发酵五子衍宗方,检测血清生化指标和盲肠微生物。结果表明:与对照组相比,在产蛋后期罗曼蛋鸡基础日粮中添加0.25%的发酵五子衍宗方可以显著提高血清球蛋白和总蛋白含量,且显著高于未发酵五子衍宗方处理;添加0.25%和0.50%的发酵五子衍宗方显著降低血清低密度脂蛋白、尿素氮和肌酐含量;添加0.75%的发酵五子衍宗方显著降低血清低密度脂蛋白、尿素氮含量、谷丙转氨酶活性、总胆红素和直接胆红素含量。在盲肠微生物菌群中,添加0.25%的发酵五子衍宗方显著降低Prevotellaceae_UCG_001的相对丰度;添加0.50%的发酵五子衍宗方显著降低unclassified_Lachnospiraceae的相对丰度;补充0.75%的发酵五子衍宗方显著降低unclassified_Bacteroidales的相对丰度。综上发现,在蛋鸡基础日粮中添加0.25%和0.50%的发酵五子衍宗方可以改善蛋鸡肝肾功能和盲肠菌群组成。The objective of this study was to investigate the effects of fermented Wuzi Yanzong prescription on the serum biochemical indexes and cecal microflora of Roman laying hens at the late laying stage.Roman laying hens were allocated into 5 groups.The control group was fed with the basal diet,while those in other groups received the basal diet supplemented with 0.50%unfermented Wuzi Yanzong prescription and 0.25%,0.50%,and 0.75%fermented Wuzi Yanzong prescription,respectively.The results indicated that compared with the control group,supplementing 0.25%fermented Wuzi Yanzong prescription elevated the serum levels of globulin and total protein,which surpassed those in the group supplemented with 0.50%unfermented Wuzi Yanzong prescription.Supplementing 0.25%and 0.50%fermented Wuzi Yanzong prescription lowered the serum levels of low-density lipoprotein,urea nitrogen,and creatinine.Supplementing 0.75%fermented Wuzi Yanzong prescription lowered the serum levels of low-density lipoprotein,urea nitrogen,glutamic-pyruvic transaminase,total bilirubin,and direct bilirubin.Furthermore,supplementing 0.25%,0.50%,and 0.75%fermented Wuzi Yanzong prescription decreased the relative abundance of Prevotellaceae_UCG_001,unclassified_Lachnospiraceae,and unclassified_Bacteroidales,respectively,in cecal microflora.In conclusion,this study suggests that supplementing 0.25%and 0.50%fermented Wuzi Yanzong prescription in the diet of laying hens can enhance the liver and kidney functions and improve the cecal microflora.
