The invention relates to the field of feed for livestock and poultry and in particular relates to a laying hen feed for improving egg yield. The feed is prepared from the following raw materials in percentage by weight: 50-60 parts of barley malt root, 80-90 parts of oat powder, 160-180 parts of maize meal, 65-75 parts of corn germ, 50-60 parts of walnut kernel meal, 45-60 parts of wood cottonseed meal, 45-50 parts of bean cake, 40-50 parts of rapeseed protein, 4-5 parts of synanthrin, 2-3 parts of pineapple juice, 2-3 parts of hydrilla powder, 2-3 parts of choline chloride, 2-3 parts of duck blood meal, 2-3 parts of shell powder, 4-5 parts of water spinach, 2-3 parts of imported cabbageworm powder, 1-2 parts of bone meal, 0.5-1 part of beef tallow, 2-3 parts of fermented blank bean, 4-5 parts of buckwheat leaf and 4-5 parts of a phagostimulant.
