LI Bin1,CHEN Jin1,WANG Jing2,et al.(1.Institute of Feedstuffs,Sichuan Animal Science Academy,Sichuan Chengdu 610066,China;2.Leshan Shenlong Feed Co.Ltd.in Sichuan Province,Sichuan Leshan 614000,China)  
The experiment was conducted to assess the effect of commercial laying hens that fed different levels of palm kernel meal(PKM).A total of 504 215-days-old Lohmann pink-shell laying hens were randomly assigned to 3 treatments with 5 replicates and 36 hens in each replicate.Two diets added two different levels of PKM and one commercial diet without PKM were fed to 3 treatments in the experiment.The results showed that there were no significant effects of different PKM levels on the average daily feed intake,laying rate,average egg weight,feed conversion efficiency,eggshell strength and Hough Unit.It was evident that this particular PKM might be used up to add 3.75% or 5% in the diet had no significant effects on laying performance and egg quality.
