The invention discloses a uniform-crowning high-egg-yield laying hen nutritional set feed application method and feed thereof, and belongs to the field of feed compositions and feeding. By repeated demonstrations and laying hen laboratory screening, the feed mainly comprising corn, wheat, corn gluten meal, soybean meal, sunflower seed meal, corn by-products, soybean oil, enzyme preparations, microbial preparations, vitamin E, organic selenium, organic chromium, organic zinc and the like is developed. The set feed is divided into two stages, one ranges from crowning period 16 weeks to 2% laying rate, the other ranges from early laying peak with 2% laying rate to 28 weeks, nutritional levels designed for the two stages are different, the two stages have certain differences in raw materials, requirements for reproductive organ development, weight growth and high egg yield are met sufficiently, and the average egg weight in 28 weeks is 61.3 grams and is 3.03% higher than the average; laying rate reaches above 95%; egg yield is increased from 48.2grams/per egg/per day to 50.1grams/per egg/per day; death and culling rate of the stage from 16 weeks to 28 weeks is decreased to 0.75%; every hen lays three more eggs; and more economic benefit of 18,000 RMB is created by 10,000 hens.
