Wang Fei et al.(Wenchang Animal Husbandry and Veterinary Station of Tongcheng City,Tongcheng 231400,China)  
Objective : To investigate the effects of rhubarb on laying performance of the hens and egg quality.Methods : 430-day-old 48 healthy Roman layer hens which weight and laying performance were similar were selected and randomly divided into two groups,each group with four replicates,every replicate with six laying hens.Group A was the control group which hens fed with the basal diet,and Group B was the treatment group which hens fed with the basal diet added 1% rhubarb.Pretest period was a week,and the test period was six weeks.Results:The experiment results showed that two groups of egg production,egg shell color,the average egg weight,egg shape index,the index of egg yolk,the rate of soft and broken egg shell,feed conversion ratio,intake and HF unit differences were not significant(P0.05).Compared with group A,the egg density of group B was increased significantly(P0.05),however,egg shell thickness was increased,but the difference was not significant(P0.05).Egg yolk color was improved significantly(P0.01),and the content of ash was also decreased significantly(P0.01),and the content of fat was decreased significantly(P0.05),then the content of protein was increased,but the difference was not significant(P0.05).Conclusion : Adding 1% rhubarb in the layer diet performance is not significant impact,but it can significant improve the physical characteristics of the egg.
