Feed for laying hens, selenium-rich and zinc-rich egg, and production method of feed

The invention discloses a feed for producing selenium-rich and zinc-rich eggs. The feed for laying hens is prepared from the following raw materials in percentage by weight: 55-60% of corn, 20-25% of soybean meal, 1-3% of fish meal, 3-5% of wheat bran, 1-2% of calcium hydrophosphate, 6-8% of rock flour, 0.3% of table salt, 2-5% of selenium-rich and zinc-rich edible fungi residues and 0.5-1.5% of feed additives. By a certain ratio of selenium-rich and zinc-rich edible fungi residues which are added in the feed for laying hens, the content of selenium and zinc in the eggs is greatly increased, the disease resistance and the contagion prevention capability of the laying hens are enhanced, and the quality of egg products is improved. As shown by measurement, the content of selenium in the selenium-rich and zinc-rich eggs which are produced by means of feeding the laying hens with the feed is 0.45-0.5mg/kg, the content of zinc is 8-10mg/kg, the content of both selenium and zinc exceeds the standard of the zinc-rich and the selenium-rich eggs, and the daily requirements of people on selenium and zinc can be fully met.
