The invention discloses a feed for improving the reduction of processing characteristics of eggs caused by vanadium. The feed comprises the following components: corn, soybean oil, soybean meal, calcium carbonate, dicalcium phosphate, table salt, choline chloride, composite multi vitamins, mineral premixes, DL- methionine and premixes. The invention further provides a premix for improving the reduction of processing characteristics of eggs caused by vanadium, and the premix comprises the following components: tea polyphenol, vitamin C, vitamin E, beta-carotene, lycopene, resveratrol, sodium selenite and rice chaff. The invention further provides a preparation method of the feed for improving the reduction of processing characteristics of eggs caused by vanadium. The premix can promote the antioxidant ability of the organism of a laying hen by improving the activity of antioxidase so as to reduce the oxidative damage of a fallopian tube induced by the vanadium and improve the reduction of the processing quality of the eggs caused by the vanadium.
