Abstract: The objective of this study was to investigate the effects of synbiotics on production performance, egg quality and economic benefits in laying hens. One thousand and eighty Zhengdahe laying hens at 265 days of age were selected, and divided into six groups, and six replicates per group and 30 hens per group. The test 1 group was the control group, was fed a corn-soybean meal diet, and the test 2 to 6 groups were fed with the basal diet supplemented with 0.05%, 0.1%, 0.2%, 0.5%, and 1% of synbiotics. The experiment lasted for 60 days. The results showed that the test 3 to 5 groups of ratio of feed to egg were lower 6.96 (P<0.05), 7.33% (P<0.05) and 8.06% (P<0.05) compared with the control group, respectively, egg production rate were higher 4.05% (P<0.05), 3.54% (P<0.05) and 6.17% (P<0.05). The test 5 group of shell thickness, eggshell color, eggshell strength and Haugh unit were higher 5.85% (P<0.05),6.50% (P<0.05),15.49% (P<0.05) and 2.52% (P<0.05).Therefore, the supplementation of 0.5% synbiotics could improve production performance and egg quality for laying hens, and had significant effect.
