Abstract：The experiment was to investigate the effect of fermented hybrid Broussonetia papyrifera leaves on production performance,egg quality,serum biochemical parameters and intestinal tissue morphology of Hyline Brown laying hens.Four hundred and fifty 24-week-old Hyline Brown laying hens were randomly divided into five groups,with six replicates in each group and 15 hens in each replicate.The hens in control group,T1 group,T2 group,T3 group and T4 group were fed with diets containing 0,1.5%,2.5%,3.5%and 4.5%fermented hybrid Broussonetia papyrifera leaves,respectively.The experiment lasted for 56 d.The results showed that compared with control group,the total cholesterol content of eggs in T4 group was significantly reduced by 9.90%(P＜0.05).The content of ALB in T3 group was increased by 5.52%(P＜0.05),the content of TP,GLB and ALB in T4 group was significantly increased(P＜0.05),and the content of UA was significantly decreased(P＜0.05).Compared with control group,the height of duodenal villi in T4 group was significantly increased by 9.24%(P＜0.05),the depth of duodenal crypt in T1 group,T2 group and T3 group was decreased by 23.87%,27.80%and 22.35%respectively(P＜0.01),and the V/C of duodenum was significantly increased by 30.26%,23.43%and 27.68%,respectively(P＜0.05).Intestinal sections showed no abnormalities in the tissues of each group.The experiment indicates that supplementing with fermented hybrid Broussonetia papyrifera leaves in basal diet has no adverse effect on production performance of laying hens,but it can reduce the cholesterol content of eggs,improve the protein utilization rate,improve serum biochemical indexes and intestinal tissue morphology.
