The objective of the present experiment was to investigate effect dietary palm kernel meal (PKM) and β-xylanase supplementation on productive performance, egg quality, fatty liver incidence, excreta characteristics in laying hens. A total 320 Hy-Line Brown hens (33 weeks age) were allotted 1 4 treatments with 8 replicates a feeding trial. Each replicate consisted 10 consecutive cages hen per cage. corn-soybean meal-based control diet prepared. Additional prepared by including 10% PKM partial replacement corn, soybean meal, animal fat. In addition, 0.025% supplemented at expense celite those 2 diets produce treatment × factorial arrangement. All provided water ad libitum for weeks. Results indicated no significant interactions between inclusion all measurements; therefore, main effects mainly discussed. Hens fed containing had greater (p < 0.05) feed intake yolk color than PKM. However, did not influence incidence characteristics. Dietary measurements, regardless conclusion, can be potential ingredient diet. It appears that used current has little layer productivity,
