The invention provides a quail feed for improving laying rate and egg quality and a preparation method thereof. The quail feed is prepared from the following raw materials in parts by weight: 40-65 parts of grains, 5-25 parts of bean pulp, 1-6 parts of sesame-seed cake, 1-2 parts of rapeseed cake, 2-6 parts of DDGS, 1-5 parts of corn gluten meal, 1-4 parts of bread crumbs, 1-3 parts of bean dregs,1-3 parts of instant noodle residues, 0.4-1.5 parts of grease, 0.1-0.3 part of salt, 0.1-0.5 part of amino acid, 2-5 parts of shell powder, 3-10 parts of mountain flour, 0.5-1 part of calcium hydrophosphate, 0.03-0.1 part of probiotics, 0.1-0.5 part of decavitamin, 0.1-0.5 part of compound trace elements, 0.05-0.1 part of a compound enzyme preparation, 0.05-0.15 part of choline chloride, 0.1-0.3part of baking soda, 0.01-0.04 part of high-temperature-resistant phytase, 0.01-0.03 part of glucose oxidase, 0.1-0.3 part of yeast culture and 0.03-0.05 part of butyrate. According to the quail feedprepared by the invention, various raw materials and functional additives are scientifically compounded, and the fertility, disease resistance and body health state of quails are obviously improved, so that the laying rate and egg quality of the quails are improved.
